ServletRequestHandledEvent missing request.getParameterMap()

[frankluo]

We have a business need to track all http request parameters for debugging and data mining purpose. I think implementing an ApplicationListener is ideal for things like this (pls correct me if I am wrong). However, when ServletRequestHandledEvent is populated in FrameworkServlet.processRequest(), request parameters are left out.

Is it possible to add the parameters to ServletRequestHandledEvent, or better yet, making request/response accessable in the Event class?

thx.

You should be able to implement that basic functionality with a Servlet Filter - or if you could benefit from IoC or shared resources managed by Spring, then you could consider implementing a HandlerInterceptor.

Why should we used a handlerInterceptor as a servlet filter provides the same functionnality?
