Problem
Define a pointcut for annotated methods. The most example are based only on @within or @annotation which has the downside that the aspect is added to all methods and the check of the annotation is executed during runtime.
Solution
@Aspect
@Component
public class MethodAspect {
/**
* This ensures that the aspect is only woven into methods with the annotation.
* Otherwise all methods are woven!
*/
@Pointcut("execution(@MethodAnnotation * * (..))")
private void isAnnotated() {};
/**
* (optional) Limit package scan to our project only
*/
@Pointcut("execution(* your.project.package..*(..))")
private void isInPackage() {};
@Around("isAnnotated() && isInPackage() && @annotation(annotation)")
public Object logExecutionTime(ProceedingJoinPoint joinPoint,
MethodAnnotation annotation) throws Throwable {
return joinPoint.proceed();
}
