SpringBoot快速HelloWorld入门

 

1、新建maven项目

 

2、pom.xml 里添加SpringBoot所依赖的jar包

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.3.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

　　保存后、自动下载这一系列的相关的jar包（太多的无法完全截图）

 

3、在src/main/java 目录下新建package   com.st.controller   

 

4、在 controller 中新建

TestController.java

 

package com.st.controller;

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

@RestController
@EnableAutoConfiguration
public class TestController {
	@RequestMapping("/hello")   //访问地址http://localhost:8080/hello
	public String hello(){
		return "success";
	}
	
	
	public static void main(String[] args) {
		//运行
		SpringApplication.run(TestController.class, args);
	}
	
}
