Maven配置SpringBoot（IDEA集成SpringBoot）

最近要用SpringBoot做一個小項目，原本準備去找一個demo，發現別人的在我的環境無法運行，於是就自學了一下。不妥之處大家指出，多多指點。

IDEA集成SpringBoot

環境準備：

              IDEA 2019.3    win10   jdk1.8

項目的結構

1. 點擊File ---->new ----->Project

 2.選擇maven選項 ----> 點擊 create from archetype -------->xxxx

 3.給他取名

 

4.完成

 

5. POM.xml配置

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

      </plugin>

  </build>

</project>

6.Application.java

package com.springboot.demo.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@SpringBootApplication
public class Application {

    @RequestMapping("/hello")
    public String hello() {
        return "hello";
    }

    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);
    }
}

 

如果代碼無jar依賴 引入配置 刷新一下 

 

 最後 運行Application.java方法

http://localhost:8080/hello
