springboot模板

Thymeleaf模板

关于Thymeleaf的优点，我只说一条：它就是html页面。下面直接上代码

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.yml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

实体类 User

package com.liuwenwu.springboot01.entity;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

/**
 * @author LWW
 * @site www.lww.com
 * @company
 * @create 2019-11-07 16:25
 *
 * @Data Set Get Tostirng
 *
 *
 */

@Data
public class User {

    private String uid;
    private String uname;

    public User() {
    }

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

ThymeleafController

package com.liuwenwu.springboot01.controller;

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

import javax.servlet.http.HttpServletRequest;
import java.util.ArrayList;
import java.util.List;

/**
 * @author LWW
 * @site www.lww.com
 * @company
 * @create 2019-11-08 11:05
 */

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

    @RequestMapping("/list")
    public ModelAndView list(){
        ModelAndView mv =new ModelAndView();
        List list =new ArrayList();
        list.add(new User("1","zs"));
        list.add(new User("2","ls"));
        list.add(new User("3","ww"));

        mv.addObject("userList",list);
        mv.addObject("msg","<span style='color:red'>天王盖地虎，宝塔镇河妖</span>");
        mv.addObject("name","zs");
        mv.setViewName("list");
        return mv;
    }


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

}
