开始的配置环节

参考文章

具体的配置

1. 本地的 pom.xml的配置

2. 创建标准的 spring boot 目录之后可能会报java: Compilation failed: internal java compiler error的错误,解决方法:
   改为和当前 java JDK 相对应的版本。

查看是否跑起来了。

1. helloController 中的基本代码

package com.yusael.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class helloController {
    @GetMapping("/hello")
    @ResponseBody
    public String hello(){
        return "hello";
    }
}

Application 中的基本代码

package com.yusael;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        System.out.println("启动 spring boot");
        SpringApplication.run(Application.class);
    }
}
