创建子模块：（myinterface）
实体类：UserAddress
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

super();
// TODO Auto-generated constructor stub
}

super();
this.id = id;
this.userAddress = userAddress;
this.userId = userId;
this.consignee = consignee;
this.phoneNum = phoneNum;

UserService
/**

*/
public interface UserService {
/**
* 按照用户id返回所有的收货地址
* @param userId
* @return
*/
public List<UserAddress> getUserAddressList(String userId);
}
OrderService
public interface OrderService {
/**
* 初始化订单
* @param userId
*/

}
创建用户子模块：(user-service)

实现UserService：
@com.alibaba.dubbo.config.annotation.Service //暴露服务
@Component
public class UserServiceImpl implements UserService {
public List<UserAddress> getUserAddressList(String userId) {
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","101-56253825", "Y");
UserAddress address2 = new UserAddress(2, "深圳市宝安区西部硅谷大厦B座3层","1","王老师", "010-562531", "N");
return Arrays.asList(address1, address2);
}
}
配置Dubbo（application.properties）
dubbo.application.name=user-service
dubbo.registry.address=127.0.0.1:2181
dubbo.registry.protocol=zookeeper
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880
dubbo.monitor.protocol=registry
spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8
启动类：
@EnableDubbo //开启基于注解的dubbo配置
@SpringBootApplication
public class UserServiceApplication {
public static void main(String[] args) {
SpringApplication.run(UserServiceApplication.class, args);
}
}
创建Order子模块：(order-service)
引入依赖：

实现OrderService：
@Service
public class OrderServiceImpl implements OrderService {
@Reference //Bubbo提供，自动发现已注册的服务，远程引用
UserService userService;
public List<UserAddress> initOrder(String userId) {
System.out.println(userId);
//调用UserService查询用户收货地址
List<UserAddress> userAddressList = userService.getUserAddressList(userId);
return userAddressList;
}
}
Controller：
@Controller
public class OrderController {
@Autowired
OrderService orderService;
@ResponseBody
@RequestMapping("/initOrder")
public List<UserAddress> initOrder(@RequestParam("uid") String userId){
return orderService.initOrder(userId);
}
}
配置Dubbo（application.properties）
server.port=8081
dubbo.application.name=order-service
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.monitor.protocol=registry
spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8
启动类：
@EnableDubbo
@SpringBootApplication
public class OrderServiceApplication {
public static void main(String[] args) {
SpringApplication.run(OrderServiceApplication.class, args);
}
}
测试
启动zookeepter
启动user模块，启动order模块。
访问localhost:8081/initOrder?uid=1
