SpringBoot整合Freemarker的基本步驟

2022-02-10 13:01:11

新增pom依賴

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

在application.yml中新增相關設定

# 設定freemarker
spring:
  freemarker:
    # 設定模板字尾名
    suffix: .ftl
    # 設定檔案型別
    content-type: text/html
    # 設定頁面編碼格式
    charset: UTF-8
    # 設定頁面快取
    cache: false
    # 設定ftl檔案路徑
    template-loader-path:
      - classpath:/templates
  # 設定靜態檔案路徑，js,css等
  mvc:
    static-path-pattern: /static/**

建立freemarker模板

目錄：src/main/resources 建立templates資料夾，資料夾裡新建freemarker.ftl檔案

<!DOCTYPE>
<html>
    <head>
        <title>freemark</title>
    </head>
    <body>
        <h1>Hello ${name} from resource freemark!</h1>
    </body>
</html>

建立控制層

package com.ahut.action;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
/**
 * 
 * @ClassName: FreemarkerAction
 * @Description: freemarker控制層
 * @author cheng
 * @date 2018年1月22日 下午8:19:39
 */
@Controller
@RequestMapping(value = "/freemarker")
public class FreemarkerAction {
    /**
     * 紀錄檔管理
     */
    private static Logger log = LoggerFactory.getLogger(FreemarkerAction.class);
     * 
     * @Title: toDemo
     * @Description: 跳轉freemarker頁面
     * @param mv
     * @return
    @RequestMapping(value = "/toDemo")
    public ModelAndView toDemo(ModelAndView mv) {
        log.info("====>>跳轉freemarker頁面");
        mv.addObject("name", "jack");
        mv.setViewName("freemarker");
        return mv;
    }
}

測試存取

啟動專案，輸入http://localhost:8080/freemarker/toDemo，看到以下介面

Freemarker獲取專案根路經

application.properties

spring.freemarker.request-context-attribute=request

ftl

<#assign base=request.contextPath />
<!DOCTYPE html>
<html lang="zh">
<head>
    <base id="base" href="${base}" rel="external nofollow" >
    <title>首頁</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <link href="${base}/static/bootstrap-3.3.4/css/bootstrap.min.css" rel="external nofollow"  rel="stylesheet">
    <script src="${base}/static/bootstrap-3.3.4/js/bootstrap.min.js"></script>

var base = document.getElementById("base").href;
// 與後臺互動
_send = function(async, url, value, success, error) {
    $.ajax({
        async : async,
        url : base + '/' + url,
        contentType : "application/x-www-form-urlencoded; charset=utf-8",
        data : value,
        dataType : 'json',
        type : 'post',
        success : function(data) {
            success(data);
        },
        error : function(data) {
            error(data);
        }
    });
};

Springboot設定靜態資源

package com.ahut.config;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
/**
 * @author cheng
 * @className: WebConfig
 * @description: 靜態資源設定類
 * @dateTime 2018/4/19 17:59
 */
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
    /**
     * 紀錄檔管理
     */
    private Logger log = LoggerFactory.getLogger(WebConfig.class);
     * @description:
     * @author cheng
     * @dateTime 2018/4/19 17:59
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        log.info("設定靜態資源所在目錄");
        // 和頁面有關的靜態目錄都放在專案的static目錄下
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
    }
}

Freemarker頁面參照靜態資源（CSS、JS）
