Hello ,
For struts1, we use "doFilter"
public void doFilter(
ServletRequest req,
ServletResponse res,
FilterChain chain)
throws IOException, ServletException
{
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
HttpSession session = request.getSession();
If not login successfully:
ActionConfig action = ...
this.sendRedirect(request, response, action.getPath());
else {
chain.doFilter(req,res);
}
}
in web.xml, all classes/actions need be filtered by this actionClass.
For struts2, do you have a good example for login checking? Moreover,
before each action/class is called, a login checking will be done
automatically. If user logins successfully, allow user action to be
processed; otherwise, return error msg to default login page.
Thank you!
