注解配置

需要 2.5.7 及以上版本支持

服务提供方

Service注解暴露服务

  1. import com.alibaba.dubbo.config.annotation.Service;
  3. @Service(timeout = 5000)
  4. public class AnnotateServiceImpl implements AnnotateService { 
  5.     // ...
  6. }

javaconfig形式配置公共模块

  1. @Configuration
  2. public class DubboConfiguration {
  4.     @Bean
  5.     public ApplicationConfig applicationConfig() {
  6.         ApplicationConfig applicationConfig = new ApplicationConfig();
  7.         applicationConfig.setName("provider-test");
  8.         return applicationConfig;
  9.     }
  11.     @Bean
  12.     public RegistryConfig registryConfig() {
  13.         RegistryConfig registryConfig = new RegistryConfig();
  14.         registryConfig.setAddress("zookeeper://127.0.0.1:2181");
  15.         registryConfig.setClient("curator");
  16.         return registryConfig;
  17.     }
  18. }

指定dubbo扫描路径

  1. @SpringBootApplication
  2. @DubboComponentScan(basePackages = "com.alibaba.dubbo.test.service.impl")
  3. public class ProviderTestApp {
  4.     // ...
  5. }

服务消费方

Reference注解引用服务

  1. public class AnnotationConsumeService {
  3.     @com.alibaba.dubbo.config.annotation.Reference
  4.     public AnnotateService annotateService;
  6.     // ...
  7. }

  11.     @Bean
  12.     public ConsumerConfig consumerConfig() {
  13.         ConsumerConfig consumerConfig = new ConsumerConfig();
  14.         consumerConfig.setTimeout(3000);
  15.         return consumerConfig;
  16.     }
  18.     @Bean
  19.     public RegistryConfig registryConfig() {
  20.         RegistryConfig registryConfig = new RegistryConfig();
  21.         registryConfig.setAddress("zookeeper://127.0.0.1:2181");
  22.         registryConfig.setClient("curator");
  23.         return registryConfig;
  24.     }
  25. }

  1. @SpringBootApplication
  2. @DubboComponentScan(basePackages = "com.alibaba.dubbo.test.service")
  3. public class ConsumerTestApp {
  4.     // ...
  5. }
