@Annotation

The @annotation() pointcut designator in Aspect-Oriented Programming (AOP) is used to match join points where the subject of the join point (typically a method) is annotated with a specific annotation. This pointcut is useful for applying advice based on annotations present on methods, allowing you to manage cross-cutting concerns like security, transactions, or logging in an annotation-driven manner.

Syntax​

@annotation(annotation-type)
  • annotation-type: The fully qualified name of the annotation type to match.

Example​

@Pointcut(value = "@annotation(com.ayah.aop.annotation.Test)")
public void executionAllMethod() {
}

com.ayah.aop.annotation.Test:

  • This specifies the fully qualified name of the annotation to be matched. In this case, it refers to the Test annotation within the package com.ayah.aop.annotation.
