Springboot框架搭建

Eclipse+Maven
1.新建一个maven-webapp项目，并删除webapp文件夹


2.添加项目依赖
（1）将项目添加为Springboot的子项目，并添加依赖

	<parent>
	  	<groupId>org.springframework.boot</groupId>
	  	<artifactId>spring-boot-starter-parent</artifactId>
	  	<version>2.0.6.RELEASE</version>
	</parent>
	<dependencies>
    	<dependency>
    		<groupId>org.springframework.boot</groupId>
    		<artifactId>spring-boot-starter-web</artifactId>
    	</dependency>
	</dependencies>

3.在包目录下新建一个启动类

3.新建一个文件为application.properties

写上项目配置

server.port=8081//更改端口号为8081

4.新建main方法编写启动方法

package com.mm;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MainApp{	

	public static void main(String[] args) {
		SpringApplication.run(MainApp.class, args);
	}

}

5.新建controller组件

package com.mm.test.controller;

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

@Controller
public class TestController {
	
	@RequestMapping("/")
	public String test() {
		return "hello";
	}
	
}

6.启动MainApp，在浏览器中输入localhost:8081就可以看见效果
7.项目代码
