什么是为Spring AOP注入相同服务实例的最佳方式 [英] Whats the best way to inject same instance of service in service for Spring AOP

问题描述

我是一个使用Spring的@Service构造型注释的ServiceImpl，并且有两个方法，每个方法都使用Spring拦截的自定义注释进行注释。

I'va a ServiceImpl with is annotated with @Service stereotype of Spring and have two methods in it each one is annotated with custom annotations which are intercepted by Spring.

@Service    
public class ServiceImpl implements Service{

       @CustomAnnotation
       public void method1(){
       ...
       }

       @AnotherCustomAnnotation
       public void method2(){
        this.method1();   
        ...
       }
    }
}

现在Spring使用基于代理的AOP方法，因此当我使用 this.method1（） @CustomAnnotation的拦截器将无法拦截此调用时，我们曾经注入此在另一个FactoryClass中提供服务，这样我们就可以获得代理实例，例如 -

Now Spring uses proxy based AOP approach and hence as I'm using this.method1() interceptor for @CustomAnnotation will not able to intercept this call, We used to inject this service in another FactoryClass and in that way we were able to get the proxy instance like -

  @AnotherCustomAnnotation
    public void method2(){
        someFactory.getService().method1();   
        ...
    }

我现在正在使用Spring 3.0.x ，这是获取代理实例的最佳方法吗？

I'm now using Spring 3.0.x, which is the best way to get the proxy instance?

推荐答案

另一种方法是使用AspectJ和@Configurable。
春天似乎走向了这些日子（偏爱）。

The other alternative is to use AspectJ and @Configurable. Spring seems to be going towards these days (favoring).

如果您使用Spring 3，我会调查它，因为它比基于代理的aop更快（性能）更灵活。

I would look into it if you are using Spring 3 as it is faster (performance) and more flexible than proxy based aop.
