1.下载maven并解压  
[http://maven.apache.org/][http_maven.apache.org]  
2.配置eclipse中要使用maven,将maven解压好的路径配置进来  
Window->Preferences->Maven->Installations->add

3.配置要使用的maven的setting配置文件(在maven的conf目录下)，local Repository本地仓库没有的话就默认就行

如果需要指定jdk版本需要在setting中添加

4.在eclipse中新建maven工程  
(1).new maven Project  
(2).选择默认

(3).选择quickstart

(4)设置工程名  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTEzMTEyOTE_size_16_color_FFFFFF_t_70 4]  
(5)工程创建成功  
![在这里插入图片描述][20181031144537927.PNG]  
如果程序中不出现src/main/java,src/test/java等，需要为工程设置正确的jre（建议是选装好的jdk路径，因为spring boot打包成jar包需要jdk）  
即右键工程->properties->java Build Path

5.在pom.xml中添加Spring boot依赖，更多[spring boot使用手册可参考它的用户手册][spring boot]

<parent>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-parent</artifactId>
    	<version>2.0.3.RELEASE</version>
    	<relativePath />
    </parent>
    <dependencies>
    	<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    </dependencies>

6.创建hello world测试  
(1)创建两文件，HelloSpringboot.java和MainApplication.java(主函数)  
![在这里插入图片描述][2018103115090186.PNG]

HelloSpringboot.java

package com.haha.SpringbootTest.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class HelloSpringboot { 
    
    	@RequestMapping("/hello")
    	@ResponseBody
    	public String hello()
    	{ 
    		return "hellow world";
    	}
    }

MainApplication.java

package com.haha.SpringbootTest;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class MainApplication { 
    
    	public static void main(String[] args) { 
    		
    		SpringApplication.run(MainApplication.class, args);
    	}
    }

2.在MainApplication.java中运行工程，然后在浏览器输入http://localhost:8080/hello
