Get HttpServletRequest in Struts 2 interceptor

Question

To get the HttpServletRequest in an interceptor I used below code:

HttpServletRequest request =(HttpServletRequest) ActionContext.getContext().get(HTTP_REQUEST);

I tried to implement ServletRequestAware in the interceptor but it did not worked.

Are there any better ways to get HttpServletRequest in an Interceptor ?!

I want to develop and interceptor which prevents Ajax request from calling directly by url. Please see http://stackoverflow.com/questions/14621539/how-to-determine-whether-a-request-is-ajax-or-normal. This interceptor will be in interceptor stack which will prevent these requests. — Alireza Fattahi, Oct 08 '13 at 07:56

You need to use ActionInvocation#getInvocationContext() to retrieve your request.

public String intercept(ActionInvocation invocation) throws Exception {
    ActionContext context = invocation.getInvocationContext();
    HttpServletRequest request = (HttpServletRequest) context.get(ServletActionContext.HTTP_REQUEST);
    // ...
}

The servlet stuff you could get referencing servletConfig interceptor. After this interceptor is invoked you could get servlet stuff from ServletActionContext.

HttpServletRequest request = ServletActionContext.getRequest();

                                               .get(ServletActionContext.HTTP_REQUEST);
