服务提供方

`Service`注解暴露服务

@Service
public class AnnotationServiceImpl implements AnnotationService {
 @Override
 public String sayHello(String name) {
 return "annotation: hello, " + name;
 }
}

增加应用共享配置

# dubbo-provider.properties
dubbo.application.name=annotation-provider
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880

指定Spring扫描路径

@Configuration
@EnableDubbo(scanBasePackages = "org.apache.dubbo.samples.simple.annotation.impl")
@PropertySource("classpath:/spring/dubbo-provider.properties")
static public class ProviderConfiguration {

}

服务消费方

`Reference`注解引用服务

@Component("annotationAction")
public class AnnotationAction {

 @Reference
 private AnnotationService annotationService;

 public String doSayHello(String name) {
 return annotationService.sayHello(name);
 }
}

增加应用共享配置

# dubbo-consumer.properties
dubbo.application.name=annotation-consumer
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.consumer.timeout=3000

指定Spring扫描路径

@Configuration
@EnableDubbo(scanBasePackages = "org.apache.dubbo.samples.simple.annotation.action")
@PropertySource("classpath:/spring/dubbo-consumer.properties")
@ComponentScan(value = {"org.apache.dubbo.samples.simple.annotation.action"})
static public class ConsumerConfiguration {

}

调用服务

public static void main(String[] args) throws Exception {
 AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(ConsumerConfiguration.class);
 context.start();
 final AnnotationAction annotationAction = (AnnotationAction) context.getBean("annotationAction");
 String hello = annotationAction.doSayHello("world");
}
