服务提供方配置

package com.example.order.service; import com.example.api.Order; import com.example.api.OrderService; import org.apache.dubbo.config.annotation.Service; import java.util.Date; @Service public class OrderServiceImpl implements OrderService {     @Override     public Order getOrder() {         Order order = new Order();         order.setId(1L);         order.setOrderName("xxx");         order.setCreateTime(new Date());         return order;     } }

 application.yml

server:   port: 4059   tomcat:     uri-encoding: UTF-8   servlet:     context-path: /order #    session: #      timeout: 300s dubbo:   application:     ###########注册到注册中心的名称############     name: ordder   ###########采用协议和端口号################   protocol:     ###########采用dubbo协议####################     name: dubbo     ###########发布dubbo端口号为40591###########     port: 40591   registry:     ###########注册中心地址#####################     address: zookeeper://192.168.0.18:2181   scan:     ############实现类扫包范围###################     base-packages: com.example.order.service spring:   output:     ansi:       enabled: always

服务消费者

package com.example.user.controller; import com.example.api.OrderService; import org.apache.dubbo.config.annotation.Reference; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class UserController {     @Reference     private OrderService orderService;     @RequestMapping("/order")     public Object getUser() {         return this.orderService.getOrder();     } }

application.yml

server:   port: 4058   tomcat:     uri-encoding: UTF-8   servlet:     context-path: /user #    session: #      timeout: 300s dubbo:   application:     ##### 注册服务的名称     name: user   ##### 注册中心地址   registry:     address: zookeeper://192.168.0.18:2181   ##### 调用服务超时时间   consumer:     timeout: 5000 spring:   output:     ansi:       enabled: always

注意项目启用要使用  @EnableDubbo 
接口注册要使用： Service
接口引用要使用：Reference

@EnableDubbo

org.apache.dubbo.config.annotation.Service

org.apache.dubbo.config.annotation.Reference

@Configuration @EnableDubbo(scanBasePackages = "org.apache.dubbo.samples.simple.annotation.impl") @PropertySource("classpath:/spring/dubbo-provider.properties") static public class ProviderConfiguration { }

@Configuration @EnableDubbo(scanBasePackages = "org.apache.dubbo.samples.simple.annotation.action") @PropertySource("classpath:/spring/dubbo-consumer.properties") @ComponentScan(value = {"org.apache.dubbo.samples.simple.annotation.action"}) static public class ConsumerConfiguration { }
