1.thymeleaf模板

关于Thymeleaf的优点，我只说一条：它就是html页面。

相关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:
正式环境还是要将缓存开启的

spring:
  thymeleaf:
    cache: false

对应的后台代码
User.java

package com.lin.springboot01.entity;

import lombok.Data;

/**
 * @authorlinfan
 * @site www.linfanmage.com
 * @company xxx公司
 * @create  2019-11-07 16:31
 */
//@ConfigurationProperties(
//        prefix = "user"
//)
//@Component

@Data
public class User {
    private String uid;
    private String uname;

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

    public User(){

    }
}

ThymeleafContorller.java

package com.lin.springboot01.contorller;

import com.lin.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;

/**
 * @authorlinfan
 * @site www.linfanmage.com
 * @company xxx公司
 * @create  2019-11-08 11:13
 */
@Controller
@RequestMapping("/thymeleaf")
public class ThymeleafContorller {

    @RequestMapping("list")
    public ModelAndView list(){
        ModelAndView mv =new ModelAndView();
        List list =new ArrayList();
        list.add(new User("1","xs"));
        list.add(new User("2","LS"));
        list.add(new User("3","WW"));

        mv.addObject("userList",list);
        mv.addObject("msg","<span style='color:red'>双11剁手活动开始了</span>");
        mv.addObject("name","zs");
        mv.setViewName("list");
        return mv;
    }

//    public  String list2(HttpServletRequest request){
//        return  "list";
//    }

}

2.Freemarker模板

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-->
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <!--freemarker模板也读取需要注释标红地方-->
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <!--<include>*.properties</include>-->
                    <!--<include>*.xml</include>-->
                    <!--<include>*.yml</include>-->
                </includes>
            </resource>
        </resources>

application.yml文件的默认配置

spring:
  thymeleaf:
    cache: false
  freemarker:
    # 设置模板后缀名
    suffix: .ftl
    # 设置文档类型
    content-type: text/html
    # 设置页面编码格式
    charset: UTF-8
    # 设置页面缓存
    cache: false
    # 设置ftl文件路径，默认是/templates，为演示效果添加role
    template-loader-path: classpath:/templates/role
  mvc:
    static-path-pattern: /static/**

Role.java


package com.lin.springboot01.entity;

import lombok.Data;

/**
 * @authorlinfan
 * @site www.linfanmage.com
 * @company xxx公司
 * @create  2019-11-08 18:30
 */
@Data
public class Role {
    private  String rid;
    private  String rname;


    public Role(String rid, String rname) {
        this.rid = rid;
        this.rname = rname;
    }
    public Role(){

    }
}

FreemarkerContorller.java

package com.lin.springboot01.contorller;

import com.lin.springboot01.entity.Role;
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;

/**
 * @authorlinfan
 * @site www.linfanmage.com
 * @company xxx公司
 * @create  2019-11-08 18:24
 */
@Controller
@RequestMapping("/freemarker")
public class FreemarkerContorller {

    @RequestMapping("/list")
    public ModelAndView list(){
        ModelAndView mv =new ModelAndView();

        mv.addObject("loginName","小李飞刀");
        List list =new ArrayList();
        list.add(new Role("1","普通会员"));
        list.add(new Role("2","会员"));
        list.add(new Role("3","超级会员"));
        mv.addObject("roleList",list);

        mv.setViewName("list");

        return  mv;
    }
}
