配置文件 application.properties 

server.port=8080 //端口设置为8080


spring.thymleaf.cache=false  //清除缓存

spring.thymleaf.prefix=classpath:/templates  //查找view资源的根目录为templates

spring.thymleaf.suffix=.html  //查找view的资源的后缀

spring.thymleaf.mode=HTML5  //页面格式HTML5

spring.thymleaf.encoding=utf-8  //采用utf-8编码

spring.thymleaf.servlet.content-type=text/html  文档类型text/html

编写控制器 Controller

 新增package 

package com.bootstrap01.controller;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class indexController{
   @RequestMapping("/")    //...8080/是此处网址
   public String index(){
       return "index";
   }
}

index.html写在src/main/resources/templates下 //对应上文的根目录

运行后结果
