跟我学Spring Boot（二）Hello World

1、打开DemoApplication添加如下代码

package com.example;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

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

@Controller //1

@SpringBootApplication

public class DemoApplication {

    //2

    @RequestMapping("/helloboot")

    public String helloBoot(Model model){

        return "index";

    }

    public static void main(String[] args) {

        SpringApplication.run(DemoApplication.class, args);

    }

}

2、在resources/template/目录下新建index.html

代码如下

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8"/>

    <title>Title</title>

</head>

<body>

hello world

</body>

</html>

这里需要注意的是meta 部分一定要有结束符不然后提示下面错误

org.xml.sax.SAXParseException: 元素类型 "meta" 必须由匹配的结束标记 "</meta>" 终止。
