Java – spring AOP: @ annotation (annotation)

I (of course) try to maintain the project with many structures I don't know very well In trying to figure out the use of AOP in spring, I encountered a method with the following comments:

@Around(value =“@ annotation(annotation)”)

So @ around means that we execute the 'around' version of the method pointcut in AOP. I see I don't know what the other parts mean The spring documentation provides the following:

I don't know what this means – "methods implemented in spring AOP" sounds like suggested methods, but I don't know how I (or spring) find the suggested methods It sounds like a method with "given comments", but if so, what comments are given?

What methods does this note suggest? What else does that mean?

Solution

If you have the following spring beans:

@Component
public class foo {

    @com.pkg.Bar      
    void fooMe() {
    }
}

Then there are the following recommendations:

@Around("@annotation(com.pkg.Bar)")

The interceptor will be called around foome (or any other spring bean method annotated with @ bar)

@The transactional annotation is a good example
