DubboAPI形式简单入门

Apache Dubbo Apache Dubbo™ (incubating)是一款高性能Java RPC框架。下午重新整理一下&＃xff0c;纪录下来

1、eclipse 建立一个maven项目

4.0.0dubbolangtutudubbolangtutu0.0.1-SNAPSHOTjardubbolangtutuhttp://maven.apache.orgUTF-8com.alibabadubbo2.6.1junitjunit3.8.1testorg.apache.zookeeperzookeeper3.4.6org.slf4jslf4j-log4j12log4jlog4jorg.apache.curatorcurator-client2.11.0
org.apache.curatorcurator-framework2.11.0




2、建立接口和对应实现类

GreetingService 接口

package dubbolangtutu.dubbolangtutu.service;public interface GreetingService {public String sayHello(String name);
}


GreetingServiceImpl 实现类

package dubbolangtutu.dubbolangtutu.service;public class GreetingServiceImpl implements GreetingService {public String sayHello(String name) {return "Hello " &＃43; name;}}


2、新建生产者

package dubbolangtutu.dubbolangtutu;import com.alibaba.dubbo.config.ApplicationConfig;
import com.alibaba.dubbo.config.RegistryConfig;
import com.alibaba.dubbo.config.ServiceConfig;import dubbolangtutu.dubbolangtutu.service.GreetingService;
import dubbolangtutu.dubbolangtutu.service.GreetingServiceImpl;import java.io.IOException;public class Provider {public static void main(String[] args) throws IOException {ServiceConfig serviceConfig &＃61; new ServiceConfig();serviceConfig.setApplication(new ApplicationConfig("first-dubbo-provider"));serviceConfig.setRegistry(registry());serviceConfig.setInterface(GreetingService.class);serviceConfig.setRef(new GreetingServiceImpl());serviceConfig.export();System.in.read();}public static RegistryConfig registry() {RegistryConfig registryConfig &＃61; new RegistryConfig();registryConfig.setAddress("127.0.0.1:2181");registryConfig.setProtocol("zookeeper");return registryConfig;}
}


3、新建消费者

package dubbolangtutu.dubbolangtutu;import com.alibaba.dubbo.config.ApplicationConfig;
import com.alibaba.dubbo.config.ReferenceConfig;
import com.alibaba.dubbo.config.RegistryConfig;import dubbolangtutu.dubbolangtutu.service.GreetingService;public class Consumer {public static void main(String[] args) {ReferenceConfig referenceConfig &＃61; new ReferenceConfig();referenceConfig.setApplication(new ApplicationConfig("first-dubbo-consumer"));referenceConfig.setRegistry(new RegistryConfig("zookeeper://127.0.0.1:2181"));referenceConfig.setInterface(GreetingService.class);GreetingService greetingService &＃61; referenceConfig.get();System.out.println(greetingService.sayHello("world"));}
}


4、启动zookeeper

5、启动生产者 &＃xff0c;然后启动消费者 查看输出

消费者启动&＃xff1a;
