For example I have following methods:
public void method1(@MyAnnotation Object a, Object b..) { ... } public void method1(Object a, Object b..., @MyAnnotation Object n, ...) { ... } What is AspectJ pointcut that targets only methods that have parameters annotated with @MyAnnotation?
This annotation can be applied for ANY argument of the method.
The following pointcut should match the execution of methods in your question. I also provided a second pointcut which is only a slight modification of the first one, but you might find it useful if you need to match specific types annotated with an annotation.
public aspect AnnotatedMethodParameterMatchingAspect { /** * Matches the execution of any method having a parameter annotated with the * {@link MyAnnotation} annotation. */ pointcut executionOfMethodWithAnnotatedParameter(): execution(* *(.., @MyAnnotation (*), ..)); /** * Matches the execution of any method having a parameter annotated with the * {@link MyAnnotation} annotation where the parameter type is a {@link MyType} * (or a subtype). */ pointcut executionOfMethodWithAnnotatedTypeRestrictedParameter(): execution(* *(.., @MyAnnotation (MyType+), ..)); }
