all pages in my web application need certain data

[jpwillms]

Hi there,

I have a web application, that has certain data that every page needs. ie. Username, a dynmamically created menu, etc. I was wondering if AOP is the solution to this, so I don't have to have code put in every single controller in my application.

Any help, advice, resources you can direct me to would be greatly appretiated.

I do this in a HandlerInterceptor, in the postHandle() method.

Something like:

public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView mnv) {
if (!(mnv.getView() instanceof RedirectView)) {
mnv.getModel().put("name", object):
}
}

AOP can do this but you can use also a customized solution like SiteMesh (or Jakarta Tiles). In our application we have dynamical pages which contain a common skeleton but have to be 'decorated' differently based on some factors (like the user properties).
I don't know your requirements but give it try - it may save you some trouble .
