Redirect to dynamic URL in Spring MVC

Question

I want my Spring MVC application to redirect to a dynamic URL (submitted by the user). So if I have code like this,

@RequestMapping("/redirectToSite") protected ModelAndView redirect(     @RequestParam("redir_url") String redirectUrl,     HttpServletRequest request,      HttpServletResponse response)  {     // redirect to redirectUrl here     return ? } 

what should I write to redirect to the submitted URL? For instance http://mySpringMvcApp/redirectToSite?redir_url=http://www.google.com should redirect to Google.

Answer 1

Try this:

@RequestMapping("/redirectToSite") protected String redirect(@RequestParam("redir_url") String redirectUrl)  {     return "redirect:" + redirectUrl; } 

This is explained in 16.5.3.2 The redirect: prefix of Spring reference documentation. Of course you can always do this manually:

response.sendRedirect(redirectUrl);
