本文详细介绍了SpringBoot中Thymeleaf和Freemarker模板引擎的使用方法，包括pom依赖配置、控制器代码示例及HTML页面展示。通过具体案例展示了如何在SpringBoot项目中集成并使用这两种模板引擎。

springboot模板引擎

Thymeleaf模板
pom依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

Spring Boot官方文档建议在开发时将缓存关闭，那就在application.properties文件中加入下面这行

spring.thymeleaf.cache=false

正式环境还是要将缓存开启的

后台代码
User

package com.xhh.springboot01.entity;

import lombok.Data;

/**
 * @author 林耀东
 * @site www.baidu.com
 * @commpany
 * @create 2019-12-28-16:16
 */
@Data
public class User {
    private String uid;
    private String uname;
    private String pwd;

    public User(String uid, String uname, String pwd) {
        this.uid = uid;
        this.uname = uname;
        this.pwd = pwd;
    }

    public User() {
    }
}

UserController

package com.xhh.springboot01.controller;

import com.xhh.springboot01.entity.User;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.ArrayList;
import java.util.List;

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

        @RequestMapping("/list")
        public ModelAndView list(){
            System.out.println("list...");
            ModelAndView mv=new ModelAndView();
            mv.addObject("title","员工列表");
            List<User> list=new ArrayList<>();
            list.add(new User(""+1,"zs",123+""));
            list.add(new User(""+2,"ls",456+""));
            list.add(new User(""+3,"22",789+""));
            mv.addObject("users",list);
            mv.addObject("msg","<span style='color:red'>优秀员工是张三</span>");
            mv.setViewName("list");
            return mv;
        }
}

Freemarker模板

导入pom依赖

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

<!--可以不加，但是做项目的时候可能会用-->
 <resources>
            <!--解决mybatis-generator-maven-plugin运行时没有将XxxMapper.xml文件放入target文件夹的问题-->
