Spring Aspect Question

[Jeremy Odell]

I am in the process of using the @AfterReturning advice. I have set this up to be used for an annotation I have created. The advice looks like:

@AfterReturning(value = "execution(@com.rbs.etspii.aspects.CheckAssetType com.rbs.base.common.RBSValidationResult submit*(..))", returning = "result")

Now I have set up my Annotation to have certain parameters set. I would like to use these in the above advice.

How do I pass in the annotation?


Thanks,
Jeremy

Hi Jeremy.

Using the @Annotation designator or, if it is an argument that is annotated, then the @Args, or if it is the target that is Annotated then @Target.

In your case it would be @Annotation, so in your Pointcut Expression you add the @Annotation designator with an "and" or "&&"

so

execution(@com.rbs.etspii.aspects.CheckAssetType com.rbs.base.common.RBSValidationResult submit*(..)) && @Annotation(assetType)"

Now in your advice method you can have the parameter
myAdviceMethod(ResultType result, CheckAssetType assetType)

Like this taken from the SpringFramework documentation

And then the advice that matches the execution of @Auditable methods:

@Before("com.xyz.lib.Pointcuts.anyPublicMethod() && " + 
        "@annotation(auditable)")
public void audit(Auditable auditable) {
  AuditCode code = auditable.value();
  // ...
}

Thanks Mark, that was it.
