完整示例服务提供方
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");
}
