入门级demo,并没有数据库之类的！

1、项目结构

一个empty project下有两个module: boot-user-service-provider(服务提供者)

和 boot-order-service-consumer(服务消费者）

至于怎么在一个空项目下创建多个module自己去百度

2、服务提供者

创建SpringBoot工程：boot-user-service-provider

1）依赖【注意】坐标gmall-interface中包含了bean,和远程调用的接口，需要install进maven仓库中

parent>
    groupId>org.springframework.bootgroupId>
    artifactId>spring-boot-starter-parentartifactId>
    version>2.0.1.RELEASEversion>
    relativePath/> 
parent>

dependencies>
    dependency>
        groupId>org.springframework.bootgroupId>
        artifactId>spring-boot-starterartifactId>
    dependency>
    dependency>
        groupId>com.atguigugroupId>
        artifactId>gmall-interfaceartifactId>
        version>1.0-SNAPSHOTversion>
    dependency>
    dependency>
        groupId>com.alibaba.bootgroupId>
        artifactId>dubbo-spring-boot-starterartifactId>
        version>0.2.0version>
    dependency>
dependencies>

2）启动类

@SpringBootApplication
@EnableDubbo  //开启基于dubbo注解的开发
public class UserServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(UserServiceApplication.class,args);

    }
}

3）服务提供者向zookeeper暴露的服务

@Service     //指出暴露的服务 【注意】这是dubbo的注解。引入包时别弄错
@Component
public class UserServiceImpl implements UserService {

   public List getUserAddressList(String userId) {
      System.out.println("UserServiceImpl.....old...");
      // TODO Auto-generated method stub
      UserAddress address1 = new UserAddress(1, "北京市昌平区宏福科技园综合楼3层", "1", "李老师", "010-56253825", "Y");
      UserAddress address2 = new UserAddress(2, "深圳市宝安区西部硅谷大厦B座3层（深圳分校）", "1", "王老师", "010-56253825", "N");
      /*try {
         Thread.sleep(4000);
      } catch (InterruptedException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }*/
      return Arrays.asList(address1,address2);
   }
}

4）application.yml : dubbo关于服务提供方的一些配置

dubbo:
  application:
    name: user-service-provider
  registry:
    address: 172.20.10.14:2181
    protocol: zookeeper
  protocol:
    name: dubbo
    port: 20080

3、服务消费者

技术图片

1）依赖

parent>
    groupId>org.springframework.bootgroupId>
    artifactId>spring-boot-starter-parentartifactId>
    version>2.0.1.RELEASEversion>
    relativePath/> 
parent>

dependencies>
    dependency>
        groupId>org.springframework.bootgroupId>
        artifactId>spring-boot-starter-webartifactId>
    dependency>
    dependency>
        groupId>com.atguigugroupId>
        artifactId>gmall-interfaceartifactId>
        version>1.0-SNAPSHOTversion>
    dependency>
    dependency>
        groupId>com.alibaba.bootgroupId>
        artifactId>dubbo-spring-boot-starterartifactId>
        version>0.2.0version>
    dependency>
dependencies>

2）启动类

@EnableDubbo
@SpringBootApplication
public class OrderServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(OrderServiceApplication.class,args);
    }
}

3）控制器 controller和业务逻辑层

@Controller
public class OrderController {

    @Autowired
    private OrderService orderService;


    @ResponseBody
    @RequestMapping("/initOrder")
    public List initOrder(String uid){
        List userAddresses = orderService.initOrder(uid);
        return userAddresses;
    }
}

@Service
public class OrderServiceImpl implements OrderService {

    //@Autowired
    @Reference  //去注册中心寻找对应的服务
    UserService userService;

    @Override
    public List initOrder(String userId) {
        //1、查询用户的收货地址
        System.out.println("用户id:"+userId);
        List addressList = userService.getUserAddressList(userId);
        return addressList;
    }
}

4）application.xml

dubbo:
  application:
    name: order-service-provider
  registry:
    address: 172.20.10.14:2181
    protocol: zookeeper
server:
  port: 8085

4、依赖的工程

【注意】要打成jar放入maven中

public class UserAddress implements Serializable {
   
   private Integer id;
    private String userAddress; //用户地址
    private String userId; //用户id
    private String consignee; //收货人
    private String phoneNum; //电话号码
    private String isDefault; //是否为默认地址    Y-是     N-否
    
    public UserAddress() {
      super();
      // TODO Auto-generated constructor stub
   }
    
   public UserAddress(Integer id, String userAddress, String userId, String consignee, String phoneNum,
                       String isDefault) {
      super();
      this.id = id;
      this.userAddress = userAddress;
      this.userId = userId;
      this.consignee = consignee;
      this.phoneNum = phoneNum;
      this.isDefault = isDefault;
   }
   
   public Integer getId() {
      return id;
   }
   public void setId(Integer id) {
      this.id = id;
   }
   public String getUserAddress() {
      return userAddress;
   }
   public void setUserAddress(String userAddress) {
      this.userAddress = userAddress;
   }
   public String getUserId() {
      return userId;
   }
   public void setUserId(String userId) {
      this.userId = userId;
   }
   public String getConsignee() {
      return consignee;
   }
   public void setConsignee(String consignee) {
      this.consignee = consignee;
   }
   public String getPhoneNum() {
      return phoneNum;
   }
   public void setPhoneNum(String phoneNum) {
      this.phoneNum = phoneNum;
   }
   public String getIsDefault() {
      return isDefault;
   }
   public void setIsDefault(String isDefault) {
      this.isDefault = isDefault;
   }
}


public interface OrderService {

    public List initOrder(String userId);
}


public interface UserService {
   
   /**
    * 按照用户id返回所有的收货地址
    * @param userId
    * @return
    */
   public List getUserAddressList(String userId);

}

5、测试

启动两个工程

在浏览器访问：http://localhost:8085/initOrder?uid=1 成功
