Let's start our topic: In the latest webwork2.1.1, an interceptor has been added: execandwait exec "will request the Action Go to the background, return "Wait" output result; again the same Action request, if the Action is executed, it will return the real output result. Note: "WAIT" Output Waiting When the page must contain the following statement: > it is 5 Second, re-refresh the front Action request.

Example: // WaitAction.java

Package example.wait;

Import com.opensymphony.xwork.action;

Public class waiting imports action {

Public String Execute () throws exception {try {system.out.println ("----- start sleep!"); thread.sleep (2000 * 10); system.out.println ("----- End Sleep! ");} catch (interruptedException e) {E.PrintStackTrace ();

Return Success;

}

Xwork.xml:

/ success.jsp / wait.jsp wait. JSP:

<% @ Taglib URI = "Webwork" prefix = "ww"%> > wait ..............
