在 Spring AOP 的服务中注入相同服务实例的最佳方法是什么 [英] Whats the best way to inject same instance of service in service for Spring AOP

问题描述

我有一个 ServiceImpl，其中使用 Spring 的 @Service 构造型进行注释，其中有两个方法，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() 拦截器 @CustomAnnotation 将无法拦截这个调用，我们曾经在另一个 FactoryClass 中注入这个服务这样我们就能够获得代理实例，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();   
        ...
    }

我现在用的是Spring 3.0.x，哪个是获取代理实例的最佳方式?

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

推荐答案

另一种选择是使用 AspectJ 和 @Configurable.春天似乎正在走向这些天(有利于).

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，我会研究它，因为它比基于代理的 aop 更快(性能)和更灵活.

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