Springboot框架搭建

Eclipse+Maven  
1.新建一个maven-webapp项目，并删除webapp文件夹  
![新建一个Maven Project][Maven Project]  
![完成文件调整，并删除webapps文件夹(不删除也没关系)][webapps]  
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  
![该类一定要在功能模块的上级，在项目启动时需要扫描][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQyOTAzMA_size_16_color_FFFFFF_t_70]  
3.新建一个文件为application.properties  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQyOTAzMA_size_16_color_FFFFFF_t_70 1]  
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  
![测试控制器][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQyOTAzMA_size_16_color_FFFFFF_t_70 2]

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][localhost_8081]就可以看见效果
