springBoot基本配置

Spring Boot 基本配置

1、新建maven jar工程 使用依赖

<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">

<modelVersion>4.0.0</modelVersion>

<groupId>com.pinyougou</groupId>

<artifactId>springbootdemo-helloworld</artifactId>

<version>0.0.1-SNAPSHOT</version>

<!--spring boot 项目必须继承spring boot 父工程 -->

<parent>

<artifactId>spring-boot-starter-parent</artifactId>

<groupId>org.springframework.boot</groupId>

<version>1.5.6.RELEASE</version>

</parent>

<dependencies>

<!--使用spring boot 开发web项目的基础依赖 -->

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

</dependencies>

</project>

2、新建启动类

package com.springboot;

 

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

 

@SpringBootApplication

public class Application {

 

public static void main(String[] args) {

SpringApplication.run(Application.class, args);

}

}

3、启动效果

 

4、访问

 

5、添加controller

package com.springboot.controller;

 

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

 

@RestController

public class HelloController {

 

@RequestMapping("/hello")

public String hello() {

return "spring boot is so easy to learn!";

}

}

6、重新启动

 

7、访问
