| <dependencies> <dependency> <groupId>com.ittcf</groupId> <artifactId>++ittcf++ -++dubbo++ -++api++-member</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> |

application.yml

|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| server: port: 8080 dubbo: application: name: member protocol: name: dubbo port: 20880 registry: address: zookeeper://127.0.0.1:2181 scan: base-packages: com.ittcf.api.member.impl |

发布服务

|-------------------------------------------------------------------------------------------------------------------------------------------------------|
| @Service public class MemberServiceImpl implements MemberService { @Override public String getUser() { return "订单服务调用会员服务接口"; } } |

注意:@Service 注解引入为阿里巴巴注解

启动服务

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

@EnableDubbo 开启Dubbo服务功能

消费者

ittcf-dubbo-api-order-impl

Maven依赖信息

|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| <dependencies> <dependency> <groupId>com.ittcf</groupId> <artifactId>++ittcf++ -++dubbo++ -++api++-member</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> |

application.yml

|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| server: port: 8081 ###dubbo 注册服务名称 dubbo: application: name: order ###dubbo服务地址 protocol: name: dubbo port: 20880 registry: address: zookeeper://localhost:2181 consumer: timeout: 5000 |

调用服务

|-----------------------------------------------------------------------------------------------------------------------------------------------------------------|
| @Reference private MemberService memberService; @RequestMapping("/orderToMember") public String orderToMember() { return memberService.getUser(); } |

使用该 @Reference调用dubbo接口

启动项目

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