###  ###

### 1. 使用IDEA新建一个Maven项目 ###

![70][]

选择Maven后，点击next下一步

![70 1][]

![70 2][]

![70 3][]

修改项目的pom.xml文件

### 2. 创建boot-dubbo的子模块项目 ###

创建Dubbo服务接口项目，我们把项目建立在刚才我们创建的boot-dubbo项目下面，作为boot-dubbo的子模块项目进行管理。

点击我们刚才新建好的项目，新建一个boot-dubbo的子模块 项目

![70 4][]

选择Maven后点击 next

![70 5][]

配置模块参数

![70 6][]

完成项目子模块的创建

同理我们继续我们第二步的步骤，再次创建一个boot-dubbo-server这子模块项目。

创建完成后，我们的整体项目结构图如下图所示：

![70 7][]

### 3. 定义每个项目的pom.xml文件 ###

打开我们的顶层项目boot-dubbo的pom.xml文件

boot-dubbo-api的pom.xml文件

boot-dubbo-server的pom.xml文件

创建如下文件目录

application.yml

# 在这里编写springboot的配置信息

User.java

package com.boot.entity;
    
    import lombok.Data;
    
    import java.io.Serializable;
    
    @Data
    public class User implements Serializable {

            this.age = age;
        }
    
        public Integer getGender () {
            return gender;
        }
    
        public void setGender (Integer gender) {
            this.gender = gender;
        }
    }

TestService.java

package com.boot.service;
    
    import com.boot.entity.User;
    
    public interface TestService {
    
        String sayHello(String str);
    
        User findUser();
    }

TestServiceImpl.java

package com.boot.com.boot.service.impl;
    
    import com.boot.entity.User;
    import com.boot.service.TestService;
    import org.springframework.stereotype.Service;
    
    /**
     * @description: TODO
     * @author:LiBoMing
     * @date: 2018/3/30 15:54
     */
    @Service
    public class TestServiceImpl implements TestService {
    
        @Override
        public String sayHello (String str) {
            return "hello boy!";
        }
    
        @Override
        public User findUser () {
            return null;
        }
    }

TestController.java

package com.boot.controller;
    
    import com.boot.entity.User;
    import com.boot.service.TestService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    @RequestMapping("/test/")
    public class TestController {
        @Autowired
        private TestService testService;
    
        @RequestMapping("hello")
        public String hello() {
            return testService.sayHello("Hello springboot and dubbo!");
        }
    
        @RequestMapping("user")
        public User user() {
            return testService.findUser();
        }
    }

ServerApplication.java

package com.boot;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ImportResource;
    
    @SpringBootApplication
    @ImportResource({"classpath:config/spring-dubbo.xml"})
    public class ServerApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(ServerApplication.class, args);
        }
    }

spring-dubbo.xml主要是对外开放接口的配置

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
           xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://code.alibabatech.com/schema/dubbo
           http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    
     
    </beans>

最后启动就可以了
