注解配置

服务提供方

Service注解暴露服务

• import com.alibaba.dubbo.config.annotation.Service;
   
  @Service(timeout = 5000)
  public class AnnotateServiceImpl implements AnnotateService { 
      // ...
  }
  

javaconfig形式配置公共模块

@Configuration
public class DubboConfiguration {

    @Bean
    public ApplicationConfig applicationConfig() {
        ApplicationConfig applicationConfig = new ApplicationConfig();
        applicationConfig.setName("provider-test");
        return applicationConfig;
    }

    @Bean
    public RegistryConfig registryConfig() {
        RegistryConfig registryConfig = new RegistryConfig();
        registryConfig.setAddress("zookeeper://127.0.0.1:2181");
        registryConfig.setClient("curator");
        return registryConfig;
    }
}

指定dubbo扫描路径

@SpringBootApplication
@DubboComponentScan(basePackages = "com.alibaba.dubbo.test.service.impl")
public class ProviderTestApp {
    // ...
}

服务消费方

Reference注解引用服务

public class AnnotationConsumeService {

    @com.alibaba.dubbo.config.annotation.Reference
    public AnnotateService annotateService;
    
    // ...
}
