Hi,
Is it possible to specify pointcuts such as the following coded pointcuts in
the aop.xml:
public pointcut loggedGetOperations (HttpServletRequest request,
HttpServletResponse response) : args (request, response)
&& (execution (void
com.sun.bookstore1.servlets.BookStoreServlet.doGet(HttpServletRequest,
HttpServletResponse)) ||
execution (void
com.sun.bookstore1.servlets.CatalogServlet.doGet(HttpServletRequest,
HttpServletResponse)) ||
execution (void
com.sun.bookstore1.servlets.ShowCartServlet.doGet(HttpServletRequest,
HttpServletResponse)) ||
execution (void
com.sun.bookstore1.servlets.ShowCartServlet.doGet(HttpServletRequest,
HttpServletResponse)) ||
execution (void
com.sun.bookstore1.servlets.CashierServlet.doGet(HttpServletRequest,
HttpServletResponse)) ||
execution (void
com.sun.bookstore1.servlets.ReceiptServlet.doPost(HttpServletRequest,
HttpServletResponse)));
My use case is the following. I want to provide a library of useful aspects
(for instance, HttpServlet logging). I want to give the user a tool that
allows them to choose the servlets to which this aspect should be applied.
What I don't want to have to do is have the user code the aspects in any
way. Once the user has selected the servlets to which the aspect should be
applied, I'd like to jar up the aspect code and put their selected pointcuts
in the aop.xml within the jar file.
I saw the other message about specifying the pointcuts in an external file,
but the answer (use a pointcut library) wasn't really satisfying because
then I'd have to include a build step for my users (true, I could do the
build for them, but it's more complicated that way).
Is there a solution for me? Has anyone thought about the need for this if
not?
Cheers,
Craig
