I am implementing ServletRequestListener and overriding its methods requestInitialized and requestDestroyed.
When requestDestroyed is called, I want to know details like whether the request is a GET/POST request and the parameters sent along with it. What should be the approach?
public void requestDestroyed(ServletRequestEvent event) {
ServletRequest s = event.getServletRequest();
//use this to get those details
From the ServletRequestEvent passed to the ServletRequestListener you implemented, call getServletRequest to get a ServletRequest object. Then cast to the subinterface, HttpServletRequest.
From there you can interrogate for parts of the URL. See this post for a handy diagram of the various parts of a URL mapped to various methods on that class.
public void requestDestroyed(ServletRequestEvent event) {
ServletRequest s = event.getServletRequest();
HttpServletRequest request = (HttpServletRequest) s; // Cast to subinterface.
String method = request.getMethod();
Map<String,String[]> parameters = request.getParameterMap();
}
