首先一定确保zookeeper正常工作

公共接口模块

为了简化代码，可以把需要其他服务调用的接口，抽取为公共接口模块dubbo-common-service，

public interface TestService {public String clientTest();
}

服务提供方

导入dubbo、zookeeper依赖

        org.apache.dubbodubbo-spring-boot-starter3.0.5org.apache.curatorcurator-framework5.2.0org.apache.curatorcurator-recipes5.2.0org.apache.curatorcurator-x-discovery5.2.0com.pshdubbo-common-service1.0

配置文件为：

server:port: 6610 #端口
dubbo:application:name: dubbo-client #别名registry:address: zookeeper://192.168.158.159:2181  #zookeeper 地址 + 端口timeout: 230000  # 如果zookeeper是放在远程服务器上超时时间请设置长一些，不然很容易超时连接失败protocol:port: 20881  # 不同服务使用不同端口，不然会报错name: dubbo

提供方实现接口并暴露服务，在接口实现类增加@DubboService

@DubboService
public class ClientServiceImpl implements TestService {@Overridepublic String clientTest() {return "远程调用成功";}
}

启动类加上@EnableDubbo

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

接口调用方

        org.apache.dubbodubbo-spring-boot-starter3.0.5org.apache.curatorcurator-framework5.2.0org.apache.curatorcurator-recipes5.2.0org.apache.curatorcurator-x-discovery5.2.0com.pshdubbo-common-service1.0

server:port: 6620dubbo:application:name: dubbo-client #别名registry:address: zookeeper://192.168.158.159:2181  #zookeeper 地址 + 端口timeout: 230000  # 如果zookeeper是放在远程服务器上超时时间请设置长一些，不然很容易超时连接失败protocol:port: 20882  # 不同服务使用不同端口，不然会报错name: dubbo

启动类

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

controller接口

@RestController
public class DubooServerApplication {@Autowiredprivate ServerService serverService;@GetMapping("/test")public String test(String name){return serverService.serverTest(name);}}

通过本服务的Service 来远程调用接口

public interface ServerService {public String serverTest(String name) ;
}

@Service
public class ServerServiceImpl implements ServerService {@DubboReferenceprivate TestService testService;public String serverTest(String name) {return "返回结果为："+testService.clientTest()+"，参数为："+name;}}

访问controller接口，得到：

远程调用成功
