Spring Boot入門(第二課，自動創建Spring Boot web項目)

地址：https://start.spring.io/

下載完成解壓、導入

 

看下項目 的pom文件

看下pom文件，全是自動的

導入之後可以直接debug啓動

 

雖然啓動成功，但是訪問http://localhost:8080 ，提示404，因爲我們沒有寫任何東西

我們需要自己從新寫一個測試類

package com.jbz.jbzspringboot.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * @author mingjian xu
 * @date 2018-07-30
 * @describe 解釋用途
 */
@Controller
@EnableAutoConfiguration
public class SimpleController {

    @RequestMapping("/home")
    @ResponseBody
    String home(){
        return "hello world!";
    }

}

啓動還是在默認JbzSpringbootApplication的main方法

訪問http://localhost:8080/ 看到以下頁面算成功搭建
