Spring AOP: Define Pointcuts for Static methods ?

[John Vergis]

Hi,

Could anybody help me in defining Advisors for static methods.

I was able to Proxy a class [MyTestBean] using BeanNameAutoProxyCreator and was able to get the Interceptors working for that class.

I have two issues:

Firstly,
The interceptors doesn't work when the methods intercepted are static. But I wanted to define pointcuts for those methods. Could you please let me know how to set the pointcuts for these methods.

Secondly,
I am proxying a Singleton class (my constructor is private). I am getting an exception as below when i try to proxy such a class called MyTestBean1.

-- org.springframework.beans.factory.support.BeanDefinitionValidationException: No public constructor in class [class com.springaop.test.MyTestBean1]


Could anybody please help me, as I stuck bcoz of these 2 issues.

Thanks in advance
Rosy

I don't think you can. You could create a class that knows how to invoke those static methods, and apply advice against an instance of that wrapper class. But I would query the design, though - do you need these static methods? Static methods are evil. They can't implement interfaces. They are not polymorphic.

You can create a FactoryBean that knows how to instantiate your singleton. But why don't you let Spring manage this? Spring-managed beans are all singletons unless you dictate otherwise.
