java - Avoid duplicate submission of Struts 2 jsp page

Question

Hi all I've got some jsp pages and im using struts2 to handle my forms. After submitting a form by user, the url shown in address bar becomes somthing.action, so when the user refreshes the page, the forms gets submitted again. How can I handle this? after submission of a form.

Answer 1

If the goal is to prevent duplicate submission of forms then use token interceptor http://struts.apache.org/2.x/docs/token-interceptor.html or tokenSession interceptor http://struts.apache.org/2.x/docs/token-session-interceptor.html.

If you simple want to refresh the page after submit without submitting again then redirect to action where you only show results not form. Use redirectAction result for that.
