类 ReferenceBean<T>

  • 所有已实现的接口:
    org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.FactoryBean, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware
    public class ReferenceBean<T>
extends Object
implements org.springframework.beans.factory.FactoryBean, org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.DisposableBean

    Spring FactoryBean for ReferenceConfig.

    Step 1: Register ReferenceBean in Java-config class: 
     @Configuration
 public class ReferenceConfiguration {
     @Bean
     @DubboReference(group = "demo")
     public ReferenceBean<HelloService> helloService() {
         return new ReferenceBean();
     }

     // As GenericService
     @Bean
     @DubboReference(group = "demo", interfaceClass = HelloService.class)
     public ReferenceBean<GenericService> genericHelloService() {
         return new ReferenceBean();
     }
 }
    Or register ReferenceBean in xml: 
     <dubbo:reference id="helloService" interface="org.apache.dubbo.config.spring.api.HelloService"/>
 <!-- As GenericService -->
 <dubbo:reference id="genericHelloService" interface="org.apache.dubbo.config.spring.api.HelloService" generic="true"/>
    Step 2: Inject ReferenceBean by @Autowired 
     public class FooController {
     @Autowired
     private HelloService helloService;

     @Autowired
     private GenericService genericHelloService;
 }

      • getObject

        public Object getObject()
        Create bean instance.

        When Spring searches beans by type, if Spring cannot determine the type of a factory bean, it may try to initialize it. The ReferenceBean is also a FactoryBean.

        In addition, if some ReferenceBeans are dependent on beans that are initialized very early, and dubbo config beans are not ready yet, there will be many unexpected problems if initializing the dubbo reference immediately.

        When it is initialized, only a lazy proxy object will be created, and dubbo reference-related resources will not be initialized.
        In this way, the influence of Spring is eliminated, and the dubbo configuration initialization is controllable.

        Dubbo config beans are initialized in DubboConfigInitializationPostProcessor.
        The actual references will be processing in DubboBootstrap.referServices().

        指定者:
        getObject 在接口中 org.springframework.beans.factory.FactoryBean<T>
