2. 環境搭建

2.1 建立專案

2.2 引入依賴

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <excludes>
                    <exclude>
                        <groupId>org.projectlombok</groupId>
                        <artifactId>lombok</artifactId>

                </excludes>
            </configuration>
        </plugin>
    </plugins>
</build>

2.3 建立前端頁面

在webapp資料夾中建立index.jsp和login.jsp
index.jsp

<%@page contentType="text/html;UTF-8" pageEncoding="UTF-8" isErrorPage="false" %>
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
<%--受限資源--%>
<h1>系統主頁</h1>
<ul>
    <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >使用者管理</a></li>
    <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >商品管理</a></li>
    <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >訂單管理</a></li>
    <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >物流管理</a></li>
</ul>
</body>
</html>

login.jsp

<%@page contentType="text/html;UTF-8" pageEncoding="UTF-8" isErrorPage="false" %>
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
<h1>登入介面</h1>
<form action="${pageContext.request.contextPath}/user/login" method="post">
    使用者名稱:<input type="text" name="username" > <br/>
    密碼  : <input type="text" name="password"> <br>
    <input type="submit" value="登入">
</form>
</html>

2.4 設定檢視資訊

application.properties

server.port=8080
server.servlet.context-path=/shiro
spring.application.name=shiro

spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

2.5 解決IDEA衝突問題

JSP 與IDEA 與SpringBoot存在一定的不相容，修改此設定即可解決

2.6 測試搭建的環境

3. 整合Shiro

3.1 引入依賴

pom.xml

<!--引入shrio-->
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring-boot-starter</artifactId>
    <version>1.5.3</version>
</dependency>

3.2 自定義Realm

在shiro資料夾下建立realm資料夾

package com.test.shiro.realm;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

/**
 * 自定義Realm
 */
public class CustomerRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        return null;
    }
}

3.3 Shiro設定

在config資料夾中建立ShiroConfig.java

@Configuration
public class ShiroConfig {
    //ShiroFilter過濾所有請求
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //給ShiroFilter設定安全管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //設定系統受限資源
        //設定系統公共資源
        Map<String, String> map = new HashMap<String, String>();
        map.put("/index.jsp","authc");//表示這個資源需要認證和授權
        // 設定認證介面路徑
        shiroFilterFactoryBean.setLoginUrl("/login.jsp");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);

        return shiroFilterFactoryBean;
    }
    //建立安全管理器
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(Realm realm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(realm);
        return securityManager;
    }
    //建立自定義Realm
    @Bean
    public Realm getRealm() {
        CustomerRealm realm = new CustomerRealm();
        return realm;
    }
}

3.4 啟動測試

輸入http://localhost:8080/shiro/index.jsp，發現需要跳轉到login.jsp

4. 常見過濾器

注意: shiro提供和多個預設的過濾器，我們可以用這些過濾器來設定控制指定url的許可權：

5. 認證和退出

5.1 在index.jsp新增a標籤

index.jsp

<a href="${pageContext.request.contextPath}/user/logout" rel="external nofollow"  rel="external nofollow" >退出登入</a>

5.2 編寫controller

UserController.java

@Controller
@RequestMapping("/user")
public class UserController {
    @RequestMapping("logout")
    public String logout() {
        Subject subject = SecurityUtils.getSubject();
        subject.logout();
        return "redirect:/login.jsp";
    }
    @RequestMapping("/login")
    public String login(String username, String password) {
        //獲取主題物件
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.login(new UsernamePasswordToken(username,password));
            System.out.println("登入成功！！！");
            return "redirect:/index.jsp";
        } catch (UnknownAccountException e) {
            e.printStackTrace();
            System.out.println("使用者錯誤！！！");
        } catch (IncorrectCredentialsException e) {
            System.out.println("密碼錯誤！！！");
        }
        return "redirect:/login.jsp";
    }
}

5.3 修改自定義Realm

CustomerRealm.java

/**
 * 自定義Realm
 */
public class CustomerRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        String principal = (String) authenticationToken.getPrincipal();
        if ("zhangsan".equals(principal)) {
            return new SimpleAuthenticationInfo(principal,"123456",this.getName());
        }
        return null;
    }
}

5.4 修改ShiroConfig設定

ShiroConfig.java
公共資源一定是在受限資源上面，不然會造成死迴圈。

@Configuration
public class ShiroConfig {
    //ShiroFilter過濾所有請求
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //給ShiroFilter設定安全管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //設定系統受限資源
        //設定系統公共資源
        Map<String, String> map = new HashMap<String, String>();
        map.put("/user/login","anon");//表示這個為公共資源 一定是在受限資源上面
        map.put("/**","authc");//表示這個受限資源需要認證和授權
        // 設定認證介面路徑
        shiroFilterFactoryBean.setLoginUrl("/login.jsp");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);

        return shiroFilterFactoryBean;
    }
    //建立安全管理器
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(Realm realm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(realm);
        return securityManager;
    }
    //建立自定義Realm
    @Bean
    public Realm getRealm() {
        CustomerRealm realm = new CustomerRealm();
        return realm;
    }
}

5.5 測試

登入正常，登出正常，未登入和登出後不能存取index.jsp

6. MDSalt的認證實現

6.1 建立資料庫

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
-- ----------------------------
-- Table structure for t_user
-- ----------------------------
DROP TABLE IF EXISTS `t_user`;
CREATE TABLE `t_user` (
  `id` INT(6) NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(40) DEFAULT NULL,
  `password` VARCHAR(40) DEFAULT NULL,
  `salt` VARCHAR(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

SET FOREIGN_KEY_CHECKS = 1;

6.2 引入依賴

<!--引入mybatis-->
<dependency>
    <groupId>tk.mybatis</groupId>
    <artifactId>mapper-spring-boot-starter</artifactId>
    <version>2.1.5</version>
</dependency>
<!--mysql-->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>
<!--druid-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.2.6</version>
</dependency>

6.3 設定資料來源和整合mybatis

application.properties

#設定資料來源
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/springboot_shrio?characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=123456

mybatis.type-aliases-package=com.test.entity
mybatis.mapper-locations=classpath:com/test/mapper/*.xml

6.4 建立實體類entity

User.java

@Data
@Accessors(chain = true)
@NoArgsConstructor
@AllArgsConstructor
public class User {
    private String  id;
    private String username;
    private String password;
    private String salt;
}

6.5 建立DAO介面

UserDao.java

@Mapper
@Repository
public interface UserDao {
    void save(User user);

    User findByUsername(String username);
}

6.6 編寫Mapper組態檔

UserDao.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.test.dao.UserDao">

    <insert id="save" parameterType="User" useGeneratedKeys="true" keyProperty="id">
        insert into t_user values(#{id},#{username},#{password},#{salt})
    </insert>
    <select id="findByUsername" parameterType="String" resultType="User">
        select id,username,password,salt
        from t_user
        where username = #{username}
    </select>
</mapper>

6.7 建立Service介面

UserService.java

public interface UserService {
    //註冊使用者方法
    void register(User user);
    //根據使用者名稱查詢使用者
    User findByUsername(String username);
}

6.8 編寫生成隨機鹽工具類

SaltUtil.java

public class SaltUtil {
    public static String getSalt(int n) {
        char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890!@#$%^&*()".toCharArray();
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < n; i++) {
            char c = chars[new Random().nextInt(chars.length)];
            sb.append(c);
        }
        return sb.toString();
    }

    public static void main(String[] args) {
        System.out.println(getSalt(4));
    }
}

6.9 編寫Service實現類

UserServiceImpl.java

@Service("userService")
@Transactional
public class UserServiceImpl implements UserService {
    @Autowired
    private UserDao userDao;

    @Override
    public void register(User user) {
        //1.獲取隨機鹽
        String salt = SaltUtil.getSalt(8);
        //2.將隨機鹽儲存到資料
        user.setSalt(salt);
        //3.明文密碼進行md5 + salt + hash雜湊
       Md5Hash MD5 = new Md5Hash(user.getPassword(),salt,1024);
       user.setPassword(MD5.toHex());
       userDao.save(user);
    }

    @Override
    public User findByUsername(String username) {
        return userDao.findByUsername(username);
    }
}

6.10 編寫Controller

UserController.java

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/register")
    public String register(User user) {
        try {
            userService.register(user);
            return "redirect:/login.jsp";
        } catch (Exception e) {
            e.printStackTrace();
            return "redirect:/register.jsp";
        }
    }
    @RequestMapping("logout")
    public String logout() {
        Subject subject = SecurityUtils.getSubject();
        subject.logout();
        return "redirect:/login.jsp";
    }
    @RequestMapping("/login")
    public String login(String username, String password) {
        //獲取主題物件
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.login(new UsernamePasswordToken(username,password));
            System.out.println("登入成功！！！");
            return "redirect:/index.jsp";
        } catch (UnknownAccountException e) {
            e.printStackTrace();
            System.out.println("使用者錯誤！！！");
        } catch (IncorrectCredentialsException e) {
            System.out.println("密碼錯誤！！！");
        }
        return "redirect:/login.jsp";
    }
}

6.11 修改自定義Realm

CustomerRealm.java

/**
 * 自定義Realm
 */
public class CustomerRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        String principal = (String) authenticationToken.getPrincipal();
        //獲取UserService物件
        UserService userService = (UserService) ApplicationContextUtil.getBean("userService");
        //System.out.println(userService);
        User user = userService.findByUsername(principal);
        if (!ObjectUtils.isEmpty(user)) {
            return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), ByteSource.Util.bytes(user.getSalt()), this.getName());
        }
        return null;
    }
}

6.12 編寫獲取物件工具類

ApplicationContextUtil.java

@Component
public class ApplicationContextUtil implements ApplicationContextAware {

    private static ApplicationContext context;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.context = applicationContext;
    }
    //根據bean名字獲取工廠中指定bean 物件
    public static Object getBean(String beanName) {
        return context.getBean(beanName);
    }
}

6.13 修改Config

ShiroConfig.java

@Configuration
public class ShiroConfig {
    //ShiroFilter過濾所有請求
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //給ShiroFilter設定安全管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //設定系統受限資源
        //設定系統公共資源
        Map<String, String> map = new HashMap<String, String>();
        map.put("/user/login","anon");//表示這個為公共資源 一定是在受限資源上面
        map.put("/user/register","anon");//表示這個為公共資源 一定是在受限資源上面
        map.put("/register.jsp","anon");//表示這個為公共資源 一定是在受限資源上面

        // 設定認證介面路徑
        shiroFilterFactoryBean.setLoginUrl("/login.jsp");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);

        return shiroFilterFactoryBean;
    }
    //建立安全管理器

7.1.3 程式碼方式授權

OrderController.java

@Controller
@RequestMapping("order")
public class OrderController {
    @RequestMapping("save")
    public String save() {
        //基於角色
        //獲取主體物件
        Subject subject = SecurityUtils.getSubject();
        //程式碼方式
        if (subject.hasRole("admin")) {
            System.out.println("儲存訂單!");

        System.out.println("進入save方法============");
        return "redircet:/index.jsp";
    }
}

7.1.4 方法呼叫授權

OrderController.java

@Controller
@RequestMapping("order")
public class OrderController {

    @RequiresRoles(value={"admin","user"})//用來判斷角色  同時具有 admin user
    @RequiresPermissions("user:update:01") //用來判斷許可權字串
    @RequestMapping("save")
    public String save(){
        System.out.println("進入方法");
        return "redirect:/index.jsp";
    }

}

@Accessors(chain = true)
@AllArgsConstructor
@NoArgsConstructor
public class User implements Serializable {
    private String id;
    private String username;
    private String password;
    private String salt;

    //定義角色集合

@Data
@Accessors(chain = true)
@AllArgsConstructor
@NoArgsConstructor
public class Perms implements Serializable {
    private String id;
    private String name;
    private String url;
}

7.2.4 建立Dao介面

UserDao.java

//根據使用者名稱查詢所有角色
User findRolesByUserName(String username);

7.2.5 編寫Mapper實現

UserDao.xml

<resultMap id="userMap" type="User">
  <id column="uid" property="id"/>
  <result column="username" property="username"/>
  <!--角色資訊-->
  <collection property="roles" javaType="list" ofType="Role">

    <result column="rname" property="name"/>
  </collection>
</resultMap>

<select id="findRolesByUserName" parameterType="String" resultMap="userMap">
  SELECT u.id uid,u.username,r.id,r.NAME rname
  FROM t_user u
  LEFT JOIN t_user_role ur
  ON u.id=ur.userid
  LEFT JOIN t_role r
  ON ur.roleid=r.id
  WHERE u.username=#{username}
</select>

7.2.6 編寫Service介面

UserService.java

public interface UserService {
    User findRoleByUsername(String username);
}

7.2.7 編寫Service實現方法

UserServiceImpl.java

@Service("userService")
@Transactional
public class UserServiceImpl implements UserService {
    @Autowired
    private UserDao userDao;
    
    @Override
    public User findRoleByUsername(String username) {
        return userDao.findRoleByUsername(username);
    }
}

7.2.8 修改自定義Realm

CustomerRealm.java

/**

 */
public class CustomerRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        String principal = (String) principalCollection.getPrimaryPrincipal();
        //獲取UserService物件
        UserService userService = (UserService) ApplicationContextUtil.getBean("userService");
        //System.out.println(userService);
        //基於角色授權
        User user = userService.findRoleByUsername(principal);
        if (!CollectionUtils.isEmpty(user.getRoles())) {
            SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
            user.getRoles().forEach(role -> info.addRole(role.getName()));
            return info;
        }
        return null;
    }
    ......
}

7.3 資料庫實現許可權授權

7.3.1 建立Dao介面

UserDao.java

	@Mapper
@Repository
public interface UserDao {
    //根據角色id查詢許可權集合
    Role findPermByRoleId(String id);
    //根據角色id查詢許可權集合
    List<Perms> findPermsByRoleId2(String id);
}

7.3.2 編寫Mapper實現

    ......
}

7.3.6 資料庫表資料設定

7.3.7 測試

8. shiro使用快取

8.1 Cache

8.1.1 Cache 作用

Cache 快取: 計算機記憶體中一段資料

作用: 用來減輕DB的存取壓力,從而提高系統的查詢效率

流程:

8.1.2 使用shiro中預設EhCache實現快取

1.引入依賴

<!--引入shiro和ehcache-->
<dependency>
  <groupId>org.apache.shiro</groupId>
  <artifactId>shiro-ehcache</artifactId>
  <version>1.5.3</version>
</dependency>

2.開啟快取

//3.建立自定義realm
@Bean
public Realm getRealm() {
    CustomerRealm realm = new CustomerRealm();
    HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
    //設定使用MD5加密演演算法
    credentialsMatcher.setHashAlgorithmName("md5");
    //雜湊次數
    credentialsMatcher.setHashIterations(1024);
    realm.setCredentialsMatcher(credentialsMatcher);

    //開啟快取管理器
    realm.setCacheManager(new EhCacheManager());
    realm.setCachingEnabled(true);//開啟快取
    realm.setAuthenticationCachingEnabled(true);//開啟認證快取
    realm.setAuthenticationCacheName("authentication");
    realm.setAuthorizationCachingEnabled(true);//開啟授權快取
    realm.setAuthorizationCacheName("authorization");

    return realm;
}

8.1.3 測試

注意:如果控制檯沒有任何sql展示說明快取已經開啟

8.2 Redis

8.2.1 shiro中使用Redis作為快取實現

1.引入redis依賴

<!--redis整合springboot-->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

2.設定redis連線

spring.redis.port=6379
spring.redis.host=localhost
spring.redis.database=0

3.啟動redis服務

4. 開發RedisCacheManager

自定義shiro快取管理器
RedisCacheManager.java

import org.apache.shiro.cache.Cache;
import org.apache.shiro.cache.CacheException;
import org.apache.shiro.cache.CacheManager;

//自定義shiro快取管理器
public class RedisCacheManager implements CacheManager {
    //引數1:認證或者是授權快取的統一名稱
    @Override
    public <K, V> Cache<K, V> getCache(String cacheName) throws CacheException {
        System.out.println(cacheName);
        return new RedisCache<K,V>(cacheName);
    }
}

5.開RedisCache實現

//自定義redis快取的實現
public class RedisCache<k,v> implements Cache<k,v> {

    private String cacheName;

    public RedisCache() {
    }

    public RedisCache(String cacheName) {
        this.cacheName = cacheName;
    }

    @Override
    public v get(k k) throws CacheException {
        return (v) getRedisTemplate().opsForHash().get(this.cacheName, k.toString());
    }

    @Override
    public v put(k k, v v) throws CacheException {
        System.out.println("put key: "+k);
        System.out.println("put value:"+v);
        getRedisTemplate().opsForHash().put(this.cacheName,k.toString(), v);
        return null;
    }

    @Override
    public v remove(k k) throws CacheException {
        System.out.println("=============remove=============");
        return (v) getRedisTemplate().opsForHash().delete(this.cacheName,k.toString());
    }

    @Override
    public void clear() throws CacheException {
        System.out.println("=============clear==============");
        getRedisTemplate().delete(this.cacheName);
    }

    @Override
    public int size() {
        return getRedisTemplate().opsForHash().size(this.cacheName).intValue();
    }

    @Override
    public Set<k> keys() {
        return getRedisTemplate().opsForHash().keys(this.cacheName);
    }

    @Override
    public Collection<v> values() {
        return getRedisTemplate().opsForHash().values(this.cacheName);
    }

    private RedisTemplate getRedisTemplate(){
        RedisTemplate redisTemplate = (RedisTemplate) ApplicationContextUtil.getBean("redisTemplate");
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        return redisTemplate;
    }
}

6. 啟動專案測試發現報錯 錯誤解釋: 由於shiro中提供的simpleByteSource實現沒有實現序列化,所有在認證時出現錯誤資訊

解決方案如下：
實現 實體類 序列化
自定義salt實現 實現序列化介面

import org.apache.shiro.codec.Base64;
import org.apache.shiro.codec.CodecSupport;
import org.apache.shiro.codec.Hex;
import org.apache.shiro.util.ByteSource;

import java.io.File;
import java.io.InputStream;
import java.io.Serializable;
import java.util.Arrays;
//自定義salt實現 實現序列化介面
public class MyByteSource implements ByteSource, Serializable {
    private  byte[] bytes;
    private String cachedHex;
    private String cachedBase64;
    public MyByteSource(byte[] bytes) {
        this.bytes = bytes;
    }
    public MyByteSource(char[] chars) {
        this.bytes = CodecSupport.toBytes(chars);
    public MyByteSource(String string) {
        this.bytes = CodecSupport.toBytes(string);
    public MyByteSource(ByteSource source) {
        this.bytes = source.getBytes();
    public MyByteSource(File file) {
        this.bytes = (new MyByteSource.BytesHelper()).getBytes(file);
    public MyByteSource(InputStream stream) {
        this.bytes = (new MyByteSource.BytesHelper()).getBytes(stream);
    public static boolean isCompatible(Object o) {
        return o instanceof byte[] || o instanceof char[] || o instanceof String || o instanceof ByteSource || o instanceof File || o instanceof InputStream;
    public byte[] getBytes() {
        return this.bytes;
    public boolean isEmpty() {
        return this.bytes == null || this.bytes.length == 0;
    public String toHex() {
        if (this.cachedHex == null) {
            this.cachedHex = Hex.encodeToString(this.getBytes());
        }
        return this.cachedHex;
    public String toBase64() {
        if (this.cachedBase64 == null) {
            this.cachedBase64 = Base64.encodeToString(this.getBytes());
        return this.cachedBase64;
    public String toString() {
        return this.toBase64();
    public int hashCode() {
        return this.bytes != null && this.bytes.length != 0 ? Arrays.hashCode(this.bytes) : 0;
    public boolean equals(Object o) {
        if (o == this) {
            return true;
        } else if (o instanceof ByteSource) {
            ByteSource bs = (ByteSource)o;
            return Arrays.equals(this.getBytes(), bs.getBytes());
        } else {
            return false;
    private static final class BytesHelper extends CodecSupport {
        private BytesHelper() {
        public byte[] getBytes(File file) {
            return this.toBytes(file);
        public byte[] getBytes(InputStream stream) {
            return this.toBytes(stream);
}

修改自定義realm中使用的salt

@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    String principal = (String) authenticationToken.getPrincipal();
    //獲取UserService物件
    UserService userService = (UserService) ApplicationContextUtil.getBean("userService");
    //System.out.println(userService);
    User user = userService.findByUsername(principal);
    if (!ObjectUtils.isEmpty(user)) {
        return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), new MyByteSource(user.getSalt()), this.getName());
    }
    return null;
}

        System.out.println(s);
    }
}

9.2 開發頁面加入驗證碼

<form action="${pageContext.request.contextPath}/user/login" method="post">
    使用者名稱:<input type="text" name="username"> 

    密碼 : <input type="text" name="password"> 

    請輸入驗證碼: <input type="text" name="code"><img src="${pageContext.request.contextPath}/user/getImage" alt="">

    <input type="submit" value="登入">
</form>

9.3 開發控制器

@RequestMapping("getImage")
public void getImage(HttpSession session, HttpServletResponse response) throws IOException {
  //生成驗證碼
  String code = VerifyCodeUtils.generateVerifyCode(4);
  //驗證碼放入session
  session.setAttribute("code",code);
  //驗證碼存入圖片
  ServletOutputStream os = response.getOutputStream();
  response.setContentType("image/png");
  VerifyCodeUtils.outputImage(220,60,os,code);
}

9.4 放行驗證碼

ShiroConfig.java

map.put("/user/getImage","anon");//驗證碼

9.5 修改認證流程

@RequestMapping("login")
public String login(String username, String password,String code,HttpSession session) {
    //比較驗證碼
    String codes = (String) session.getAttribute("code");
    try {
        if (codes.equalsIgnoreCase(code)){
            //獲取主體物件
            Subject subject = SecurityUtils.getSubject();
                subject.login(new UsernamePasswordToken(username, password));
                return "redirect:/index.jsp";
        }else{
            throw new RuntimeException("驗證碼錯誤!");
        }
    } catch (UnknownAccountException e) {
        e.printStackTrace();
        System.out.println("使用者名稱錯誤!");
    } catch (IncorrectCredentialsException e) {
        e.printStackTrace();
        System.out.println("密碼錯誤!");
    }catch (Exception e){
        e.printStackTrace();
        System.out.println(e.getMessage());
    }
    return "redirect:/login.jsp";
}

9.6 啟動測試

10. shiro標籤在jsp使用

需要在jsp頁面中引入標籤
<%@ taglib uri="http://shiro.apache.org/tags" prefix="shiro" %>
標籤：
<shiro:authenticated> 登入之後
<shiro:notAuthenticated> 不在登入狀態時
<shiro:guest> 使用者在沒有RememberMe時
<shiro:user> 使用者在RememberMe時
<shiro:hasAnyRoles name="abc,123" > 在有abc或者123角色時
<shiro:hasRole name="abc"> 擁有角色abc
<shiro:lacksRole name="abc"> 沒有角色abc
<shiro:hasPermission name="abc"> 擁有許可權資源abc <shiro:lacksPermission name="abc"> 沒有abc許可權資源
<shiro:principal> 顯示使用者身份名稱
<shiro:principal property="username"/> 顯示使用者身份中的屬性值

11. Shiro整合springboot之thymeleaf許可權控制

11.1 引入依賴

<dependency>
    <groupId>com.github.theborakompanioni</groupId>
    <artifactId>thymeleaf-extras-shiro</artifactId>
    <version>2.0.0</version>
</dependency>

11.2 頁面中引入名稱空間

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
      xmlns:shiro="http://www.pollix.at/thymeleaf/shiro">

11.3 常見許可權控制標籤使用

<!-- 驗證當前使用者是否為「訪客」，即未認證（包含未記住）的使用者。 -->
<p shiro:guest="">Please <a href="login.html" rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >login</a></p>

<!-- 認證通過或已記住的使用者。 -->
<p shiro:user="">
    Welcome back John! Not John? Click <a href="login.html" rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >here</a> to login.
</p>
<!-- 已認證通過的使用者。不包含已記住的使用者，這是與user標籤的區別所在。 -->
<p shiro:authenticated="">
    Hello, <span shiro:principal=""></span>, how are you today?
<a shiro:authenticated="" href="updateAccount.html" rel="external nofollow" >Update your contact information</a>
<!-- 輸出當前使用者資訊，通常為登入帳號資訊。 -->
<p>Hello, <shiro:principal/>, how are you today?</p>
<!-- 未認證通過使用者，與authenticated標籤相對應。與guest標籤的區別是，該標籤包含已記住使用者。 -->
<p shiro:notAuthenticated="">
    Please <a href="login.html" rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >login</a> in order to update your credit card information.
<!-- 驗證當前使用者是否屬於該角色。 -->
<a shiro:hasRole="admin" href="admin.html" rel="external nofollow" >Administer the system</a><!-- 擁有該角色 -->
<!-- 與hasRole標籤邏輯相反，當用戶不屬於該角色時驗證通過。 -->
<p shiro:lacksRole="developer"><!-- 沒有該角色 -->
    Sorry, you are not allowed to developer the system.
<!-- 驗證當前使用者是否屬於以下所有角色。 -->
<p shiro:hasAllRoles="developer, 2"><!-- 角色與判斷 -->
    You are a developer and a admin.
<!-- 驗證當前使用者是否屬於以下任意一個角色。  -->
<p shiro:hasAnyRoles="admin, vip, developer,1"><!-- 角色或判斷 -->
    You are a admin, vip, or developer.
<!--驗證當前使用者是否擁有指定許可權。  -->
<a shiro:hasPermission="userInfo:add" href="createUser.html" rel="external nofollow"  rel="external nofollow" >新增使用者</a><!-- 擁有許可權 -->
<!-- 與hasPermission標籤邏輯相反，當前使用者沒有制定許可權時，驗證通過。 -->
<p shiro:lacksPermission="userInfo:del"><!-- 沒有許可權 -->
    Sorry, you are not allowed to delete user accounts.
<!-- 驗證當前使用者是否擁有以下所有角色。 -->
<p shiro:hasAllPermissions="userInfo:view, userInfo:add"><!-- 許可權與判斷 -->
    You can see or add users.
<!-- 驗證當前使用者是否擁有以下任意一個許可權。  -->
<p shiro:hasAnyPermissions="userInfo:view, userInfo:del"><!-- 許可權或判斷 -->
    You can see or delete users.
<a shiro:hasPermission="pp" href="createUser.html" rel="external nofollow"  rel="external nofollow" >Create a new User</a>

11.4 加入shiro的方言設定

頁面標籤不起作用一定要記住加入方言處理

@Bean(name = "shiroDialect")
public ShiroDialect shiroDialect(){
  return new ShiroDialect();
}
