使用idea2017搭建SSM框架及測試

搭建個SSM框架居然花費了我好長時間！特此記錄！

需要準備的環境：

idea 2017.1

jdk1.8

Maven 3.3.9

請提前將idea與Maven、jdk設定好，本次專案用的都是比較新的

步驟：

一、首先使用idea新建一個Maven webapp專案

點選Finish，第一次搭建可能會很慢，甚至可能需要VPN才能搭建成功

二、搭建目錄結構

我這裡列出的是搭建完了之後所有的目錄和檔案，諸位先把目錄檔案建起來，然後我在給出檔案內容

這裡的目錄建好之後還需要設定一下，讓idea識別目錄作用，選擇File-Project Structure

設定完成後ok

三、組態檔內容

到這裡基本上環境就搭建完成了，下面開始測試

四、測試

先匯入一份資料庫測試檔案

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '使用者ID',
  `email` varchar(255) NOT NULL COMMENT '使用者郵箱',
  `password` varchar(255) NOT NULL COMMENT '使用者密碼',
  `username` varchar(255) NOT NULL COMMENT '使用者暱稱',
  `role` varchar(255) NOT NULL COMMENT '使用者身份',
  `status` int(1) NOT NULL COMMENT '使用者狀態',
  `regTime` datetime NOT NULL COMMENT '註冊時間',
  `regIp` varchar(255) NOT NULL COMMENT '註冊IP',
  PRIMARY KEY (`id`),
  UNIQUE KEY `email` (`email`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
INSERT INTO `user` VALUES ('1', 'xxx', 'xxxxx', 'xxxxx', 'root', '0', '2017-03-28 09:40:31', '127.0.0.1');
SET FOREIGN_KEY_CHECKS=1;

接下來設定類

UserController

package com.chatRobot.controller;

import javax.servlet.http.HttpServletRequest;

import com.chatRobot.model.User;
import com.chatRobot.service.IUserService;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

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

    @Resource
    private IUserService userService;

    @RequestMapping("/showUser.do")
    public void selectUser(HttpServletRequest request, HttpServletResponse response) throws IOException {
        request.setCharacterEncoding("UTF-8");
        response.setCharacterEncoding("UTF-8");
        long userId = Long.parseLong(request.getParameter("id"));
        User user = this.userService.selectUser(userId);
        ObjectMapper mapper = new ObjectMapper();
        response.getWriter().write(mapper.writeValueAsString(user));
        response.getWriter().close();
    }

}

IUserDao

package com.chatRobot.dao;

import com.chatRobot.model.User;

public interface IUserDao {

    User selectUser(long id);

}

User

package com.chatRobot.model;

import java.util.Date;

public class User {

    private long id;
    private String email;
    private String password;
    private String username;
    private String role;
    private int status;
    private Date regTime;
    private String regIp;

    public long getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getRole() {
        return role;
    }

    public void setRole(String role) {
        this.role = role;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public Date getRegTime() {
        return regTime;
    }

    public void setRegTime(Date regTime) {
        this.regTime = regTime;
    }

    public String getRegIp() {
        return regIp;
    }

    public void setRegIp(String regIp) {
        this.regIp = regIp;
    }

}

IUserService

package com.chatRobot.service;

import com.chatRobot.model.User;

public interface IUserService {

    public User selectUser(long userId);

}

UserServiceImpl

package com.chatRobot.service.impl;

import com.chatRobot.dao.IUserDao;
import com.chatRobot.model.User;
import com.chatRobot.service.IUserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

@Service("userService")
public class UserServiceImpl implements IUserService {

    @Resource
    private IUserDao userDao;

    public User selectUser(long userId) {
        return this.userDao.selectUser(userId);
    }

}

UserDao.xml

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

<!-- 設定為IUserDao介面方法提供sql語句設定 -->
<mapper namespace="com.chatRobot.dao.IUserDao">

    <select id="selectUser" resultType="User" parameterType="long">
        SELECT * FROM user WHERE id = #{id}
    </select>

</mapper>

然後新建個測試類，來測試mybatis

IUserDaoTest

package com.chatRobot.dao;

import com.chatRobot.model.User;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

// 載入spring組態檔
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-mybatis.xml"})
public class IUserDaoTest {

    @Autowired
    private IUserDao dao;

    @Test
    public void testSelectUser() throws Exception {
        long id = 1;
        User user = dao.selectUser(id);
        System.out.println(user.getUsername());
    }

}

執行後結果應該是會在控制台輸出id為1的使用者名稱，沒成功的話就找BUG去吧...

繼續新建個頁面來測試springmvc和mybatis

index.html

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>test</title>
</head>
<script>
    function selectUser() {
        var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function () {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                document.getElementById("test").innerHTML = xmlhttp.responseText;
            }
        }
        xmlhttp.open("POST", "user/showUser.do", true);
        xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xmlhttp.send("id=1");
    }
</script>
<body>
<p id="test">Hello World!</p>
<button type="button" onclick="selectUser()">onclick test</button>
</body>
</html>

新建完成後設定專案執行環境，點選Run-Edit Configurations...

點選加號新建執行環境，選擇Tomcat Server-Local

選中新建好的伺服器，右邊選擇Deployment,點選加號-Atifact...

選擇第二項

然後在右邊Application context設定你的專案名

最後執行專案，在開啟的頁面中點選按鈕測試，成功的話會在頁面上顯示id為1的使用者資訊
