私有方法的方法拦截器 [英] Method Interceptor on private methods

问题描述

这里是一个问题:我有方法digest(byte[] data).它应该是私有的，因为我们真的不需要在课外使用它，但是，如果有帮助的话，只要公开，我也不会死.
问题是:我可以以某种方式将拦截器连接到它吗?事实是，它不像getBean('MyBean').digest()那样被调用，而是通过getBean('MyBean').sign(data)来调用，其中符号像

Here is a question: I have method digest(byte[] data). It should be private, because we really don't need it outside a class, however i'll not die if i make it public, if it helps.
The question is: can i somehow attach interceptor to it? The thing is that it is not called like getBean('MyBean').digest(), it is called through getBean('MyBean').sign(data) where sign is smth like

public byte[] sign(byte[] data){
   ...
   b = digest(data);
   ...
   return signature;
}

谢谢.

推荐答案

即使方法是公共的，Spring也无法拦截在包含该方法的对象中进行的方法调用.为此，您必须使用AspectJ.

Even if the method is public, Spring can't intercept method calls who are made from within the object containing the method. To achieve this, you would have to use AspectJ.
