Within

The within() pointcut designator in Aspect-Oriented Programming (AOP) is used to match join points within certain types. This pointcut is particularly useful for applying advice to all methods within a specific class or package.

Syntax​

within(type-pattern)
  • type-pattern: A pattern that specifies the types (classes or interfaces) whose join points should be matched. This can be a fully qualified class name, a package name with a wildcard, or other type pattern expressions.

Example​

@Pointcut(value = "within(com.ayah.aop.service.*)")
public void executionAllMethod() {
}

com.ayah.aop.service.*:

  • This denotes the package com.ayah.aop.service and all the classes within that package.
  • The asterisk (*) is a wildcard that matches any class within the specified package.
