项目结构

dubbo-demo

　　dubbo-api：提供api接口，一般存储实体类和接口服务

　　dubbo-provider：dubbo生产者提供服务，一般存储接口具体实现

　　dubbo-customer：dubbo消费者使用服务，分发请求

一、新建项目dubbo-demo

1、新建Maven项目，File-->new-->Project，选择Maven

2、填充GroupId、ArtifactId和Version 

3、一路Next，最后选择项目名称（之前创建过dubbo的项目，这里重命名为dubbo_demo）

4、生成项目，修改pom.xml（不修改也不影响子模块），删除src

 

 二、添加基于SpringBoot的三个子模块dubbo-api、dubbo-provider、dubbo-customer

1、添加子模块dubbo-api，项目右键-->new-->Module

 

 

 

 

 最后生成的dubbo-api 如下：

 

2、以相同的方式创建dubbo-provider和dubbo-customer如下：

 

 

三、各个模块添加代码示例

1、dubbo-api

 

phone（手机实体类）：

package com.mirana.api.model;import java.io.Serializable;import java.math.BigDecimal;/** * Title：手机 实体类 * * @CreatedBy Mirana * @DateTime 2018/5/25 8:43 */public class Phone implements Serializable {    // 主键id    private Long       id;    // 手机名称    private String     name;    // 价格    private BigDecimal price;    public Long getId () {        return id;    }    public void setId (Long id) {        this.id = id;    }    public String getName () {        return name;    }    public void setName (String name) {        this.name = name;    }    public BigDecimal getPrice () {        return price;    }    public void setPrice (BigDecimal price) {        this.price = price;    }}

 IPhoneService手机接口

package com.mirana.api.service;import com.mirana.api.model.Phone;/** * Title：手机服务接口 * * @CreatedBy Mirana * @DateTime 2018/5/25 8:45 */public interface IPhoneService {    /**     * 根据id查找手机     *     * @param id     * @return     */    Phone findById (Long id);}

在application.properties中定义端口

server.port=9011

 

2、dubbo-provider

 

 pom.xml添加dubbo-api（具体实现类要实现dubbo-api的IPhoneService接口）和Apache Dubbo的Maven依赖，红色部分为新增依赖

 添加实现类PhoneServiceImpl，@service注解是dubbo的注解，而非Spring的注解

package com.mirana.provider.service;import com.alibaba.dubbo.config.annotation.Service;import com.mirana.api.model.Phone;import com.mirana.api.service.IPhoneService;import java.math.BigDecimal;/** * Title：手机服务service * * @CreatedBy Mirana * @DateTime 2018/5/25 10:32 */@Service(version = "1.0.0")public class PhoneServiceImpl implements IPhoneService {    /**     * 根据id查找手机     *     * @param id     * @return     */    @Override    public Phone findById (Long id) {        Phone phone = new Phone();        phone.setId(id);        phone.setName("iphonex");        phone.setPrice(BigDecimal.valueOf(8848.88));        return phone;    }}

新增dubbo服务提供者的配置文件：dubbo-provider.xml

在SpringBoot的启动类DubboProviderApplication上导入dubbo-provider.xml的配置

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

在application.properties中定义端口

server.port=9012

3、dubbo-customer

1、pom.xml，与provider相似，添加dubbo-api和dubbo的依赖（红色部分）

     
         
      
       4.0.0
          
      
       com.mirana.customer
          
      
       dubbo-customer
          
      
       v1.1
          
      
       jar
          
      
       dubbo-customer
          
      
       Demo project for Spring Boot

        spring-boot-starter-parent
               
       
        2.0.2.RELEASE
               
        
           
          
              
       
        UTF-8
               
       
        UTF-8
               
       
        1.8
           
          
              
                   
        
         org.springframework.boot
                    
        
         spring-boot-starter-web

         spring-boot-starter-test
                    
        
         test
                
               
               
                   
        
         com.mirana.api
                    
        
         dubbo-api
                    
        
         v1.1

           spring

         org.apache.zookeeper
                    
        
         zookeeper
                    
        
         3.4.10
                    
                        
                             
          
           slf4j-log4j12
                              
          
           org.slf4j
                          
                     
                
               
                   
        
         com.github.sgroschupf
                    
        
         zkclient
                    
        
         0.1
                
           
          
              
                   
                        
         
          org.springframework.boot
                         
         
          spring-boot-maven-plugin
                     
                
           
      
     

2、添加视图控制器PhoneController

package com.mirana.customer.controller;import com.mirana.api.model.Phone;import com.mirana.api.service.IPhoneService;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import javax.annotation.Resource;/** * Title：TODO * * @CreatedBy Mirana * @DateTime 2018/5/25 10:59 */@RestController@RequestMapping("/phone")public class PhoneController {    @Resource    private IPhoneService phoneService;    /**     * @return     */    @RequestMapping("/findById")    public Phone findById (Long id) {        return phoneService.findById(id);    }}

3、添加dubbo服务消费者的配置文件dubbo-customer.xml

4、在SpringBoot的启动类DubboCustomerApplication上导入dubbo-customer.xml的配置

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

在application.properties中定义端口

server.port=9013

三、请求服务消费者的地址

　　查找id为3的手机：http://localhost:9013/phone/findById?id=3，返回的json数据如图

 

三、运行程序，查看dubbo-admin

1、先运行dubbo-api

　　运行DubboApiApplication的main( )方法

2、再运行dubbo-provider

　　运行DubboProviderApplication的main( )方法

3、最后运行dubbo-customer

　　运行DubboCustomerApplication的main( )方法

4、查看dubbo-admin的服务

　　http://localhost:8080/dubbo/，输入用户名root密码root

4.1提供的服务

 4.2 服务提供者

 

 4.3 服务消费者
