项目结构

代码示例

由于之前的IEchoService 的一个方法只是在服务端控制台打印，不便在浏览器测试，所以新添加的方法

api和服务端代码变更

public interface IEchoService {

    void echo();

    String echo(String msg);

}

@Service

public class EchoServiceImpl implements IEchoService {

    public void echo() {

        System.out.printf("hello");

    }

    public String echo(String msg) {

        return "echo: " + msg;

    }

}

客户端代码

• [ClientService]

@Service

public class ClientService {

    @Reference

    private IEchoService echoService;

    public String echo(String msg) {

        return echoService.echo(msg);

    }

}

• [EchoTestApp]

@RestController

@SpringBootApplication

public class EchoTestApp {

    @Autowired

    private ClientService clientService;

    @GetMapping("/hi/{name}")

    public String hello(@PathVariable(name = "name") String name) {

        return clientService.echo(name);

    }

    public static void main(String[] args) {

        System.getProperties().put("server.port", 7070);

        SpringApplication.run(EchoTestApp.class, args);

    }

    @Configuration

    @EnableDubbo(scanBasePackages = "consumer")

    @PropertySource("classpath:/dubbo-consumer.properties")

    static public class ConsumerConfiguration {

    }

}

• [dubbo-consumer.properties]

# dubbo-consumer.properties

dubbo.application.name=annotation-consumer

dubbo.registry.address=zookeeper://127.0.0.1:2181

dubbo.consumer.timeout=3000
