更新项目解决项目报错：
项目上右键--maven--update project
新建配置文件
application.properties
application.properties文件内容：
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
WEB-INF下新建jsp文件夹，新建hello.jsp文件
hello.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<body>
你好，SpringBoot!!!
</body>
</html>在项目上新建MyController.java文件
内容：
package com.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class MyController {
@RequestMapping("/")
public String start() {
return "hello";
}
}
在项目上新建启动类App.java
内容：
package com.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
@EnableAutoConfiguration
@ComponentScan(value = {"com.controller"})
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
运行：
在App.java上右键run as --java application
