屬性文件application.yaml

spring:
  application:
    name: provider
dubbo:
  application:
    name: privider
  registry:
    address: zookeeper://127.0.0.1:2181
    timeout: 20000
  protocols:
    rest:
      name: rest
      server: tomcat
      port: 8080
    dubbo:
      name: dubbo
      port: 20880
debug: true

接口api：

import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
@Path("hello")
@Consumes({MediaType.APPLICATION_JSON,MediaType.TEXT_XML})
@Produces({"application/json;charset=UTF-8"})
public interface IHelloService {

    @GET
    @Path("say")
    String hello(@QueryParam("name") String name);
}

服務provider：

import com.star.api.IHelloService;
import org.apache.dubbo.config.annotation.DubboService;
@DubboService(interfaceClass = IHelloService.class,protocol = {"rest","dubbo"},version = "1.0")
public class HelloServiceImpl implements IHelloService {
    @Override
    public String hello(String name) {
        return "hello " + name;
    }
}

啓動類：

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableDubbo(scanBasePackages = {"com.star.provider.service"})
public class ProviderApp {

    public static void main(String[] args) {
        SpringApplication.run(ProviderApp.class, args);
    }
}

測試：

public static void main(String[] args) {
        ReferenceConfig<IHelloService> referenceConfig = new ReferenceConfig<>();
        referenceConfig.setApplication(new ApplicationConfig("dubbo-demo-consumer"));
        RegistryConfig registryConfig = new RegistryConfig("zookeeper://127.0.0.1:2181");
        registryConfig.setTimeout(10000);
        referenceConfig.setRegistry(registryConfig);
        referenceConfig.setInterface(IHelloService.class);
        referenceConfig.setTimeout(10000);
        referenceConfig.setVersion("1.0");
        //referenceConfig.setProtocol("rest");
        referenceConfig.setProtocol("dubbo");
        IHelloService helloService = referenceConfig.get();
        System.out.println(helloService.hello("dubbo latest"));
    }
