problem :
i creating pointcut execution of method in class . class controller class , denoted annotation @controller , hence no bean needed same required aspect. attaching dispathcher servlet code , aspect , controller class.can identify problem is.
dispatcher servlet :

this limitation in spring aop. when use aspectj pointcuts weave aspects beans, spring use cglib generate subclass of target, , invoke aspects subclass.
if target class not have public default constructor, however, fail. cglib have ability handle this, hidden behind spring aop stuff , can't change behaviour.
i can suggest go using setter injection controller, rather constructor injection. it's not ideal, know, can't think of other workaround.
