Spring AOP point with one specific argument

I need to create an aspect that is hard for me to describe, so let me point out ideas:

  • any method inside the package (or any subpackage) com.xy ..
  • one argument of the method is an implementation of the javax.portlet.PortletRequest interface
  • there may be more arguments in the method
  • they can be in any order

I need a pointcut and "around" tip with the PortletRequest parameter specified

I currently have smt like:

@Pointcut("execution(* com.xy.*.*(PortletRequest,..)) && args(request,..)") public void thePointcut(PortletRequest request) { } @Around("thePointcut(request)") public Object theAdvice(ProceedingJoinPoint joinPoint, PortletRequest request) { ...

and get an error message:

ERROR 10: 47: 27.159 [ContainerBackgroundProcessor [StandardEngine [Catalina]]] osweb.portlet.DispatcherPortlet - Context Initialization error org.springframework.beans.factory.BeanCreationException: Error creating bean named org.springframework.web.servlet. mvc.HttpRequestHandlerAdapter ': Bean initialization failed; The nested exception is java.lang.IllegalArgumentException: w arning no match for this type name: PortletRequest [Xlint: invalidAbsoluteTypeName]

Any help is much appreciated

Regards, Dan

The UPDATE method I'm trying to intercept:

in the public class com.xyMainClass :

public String mainRender(Model model, RenderRequest request) throws SystemException

in the public class com.xyasd.HelpClass :

public final void helpAction(ActionRequest request, ActionResponse response, Model model)

In the course, I want to get an argument that implements PortletRequest, that is, RenderRequest from the first method, and ActionRequest from the second.

Regards, Dan

As this error implies, you need to use the full name PortletRequest in the point abbreviation expression - since this is a string, the import context is not available during the evaluation of the expression.

 @Pointcut("execution(* com.xy.*.*(javax.portlet.PortletRequest.PortletRequest,..)) && args(request,..)") public void thePointcut(PortletRequest request) { }

Since you already select the type in the args construct, you do not need this in the signature. The following should also work.

 @Pointcut("execution(* com.xy.*.*(..)) && args(request,..)") public void thePointcut(PortletRequest request) { }

This operation a and boolean, that is, it must match the template of the method, as well as the construction of args.
