Spring-Boot基本环境搭建

1.创建一个maven项目

2打开pom.xml

  <dependencies>
    <!-- 引入Springboot Web依赖 -->
    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
  </dependencies>

<!-- 引入继承springboot-parent 实现了很多jar包依赖 -->
  <parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>1.3.3.RELEASE</version>
  </parent>

然后右击项目-maven-update source eclipse会自动下载jar包

然后创建一个controller包

新建类

package com.news.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")
public String hello(){
return "success";
}

public static void main(String[] args){
//开始运行
SpringApplication.run(TestController.class, args);
}
}

然后运行，默认端口8080加上@RequestMapping里面写的映射路径

spring boot 注解：
@RestController == @Controller + @ResponseBody
@ResponseBody这个是会返回json
