How to get URL specific details and Request Type(GET, POST, PUT) from ServletRequestEvent?

Question

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

Answer 1

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();
}
