属性文件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); } 

服务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; } } 

启动类：

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); } } 

测试：

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")); }
