RE: [aspectwerkz-user] RE: Pb with annotations and constructor selection

Many thanks for the quick answer.

I wrote a star for the modifier and not for the return type but anyway that was the mistake.
Moreover, you are right. I don't wanna match the execution of constructor that are annotated but intercept operations on field...

Many thanks ;-)

in 
execution(@org.annotations.Authorization * *..*.new(..)) 

there is a star for a return type, which is not consistent since
constructor don't have a return type that you can match on.

Try:
execution(@org.annotations.Authorization *..*.new(..)) 

That said, this means
"match all execution of constructor that are annotated with the
Authorization annotation" which is different from what you are trying
to do (it seems).

For field interception you need to use a get/ set pointcut
