I am trying to implement RESTful urls in my Spring MVC application. All is well except for handling form submissions. I need to redirect either back to the original form or to a "success" page.
@Controller
@RequestMapping("/form")
public class MyController {
@RequestMapping(method = RequestMethod.GET)
public String setupForm() {
// do my stuff
return "myform";
}
@RequestMapping(method = RequestMethod.POST)
public String processForm(ModelMap model) {
// process form data
model.addAttribute("notification", "Successfully did it!");
return "redirect:/form";
}
}
However as I read in the Spring documentation, if you redirect any parameters will be put into the url. And that doesn't work for me. What would be the most graceful way around this?
I had the same problem. solved it like this:
return new ModelAndView("redirect:/user/list?success=true");
And then my controller method look like this:
public ModelMap list(@RequestParam(required=false) boolean success) {
ModelMap mm = new ModelMap();
mm.put(SEARCH_MODEL_KEY, campaignService.listAllCampaigns());
if(success)
mm.put("successMessageKey", "campaign.form.msg.success");
return mm;
}
Works perfectly unless you want to send simple data, not collections let's say. Then you'd have to use session I guess.
