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 ?!

Why do you need HttpServletRequest in interceptor? – Trait

I want to develop and interceptor which prevents Ajax request from calling directly by url. Please see #14622039. This interceptor will be in interceptor stack which will prevent these requests. – Bugaboo

Answer 1

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();

Answer 2

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);
    // ...
}
