HTTP状态405-在Spring MVC中执行返回“重定向：*。*”时，不支持请求方法“ GET”

Question

In spring MVC... I have to reload a page after the record is updated. So in the action method I am returning String and in return I am returning

 return "redirect:/recordList";

When but it is giving the exception on the page

 HTTP Status 405 - Request method 'GET' not supported

There is no exception coming on the logs.

My controller method looks like

    @RequestMapping(value= "/recordList", method = RequestMethod.POST)
    public ModelAndView getAssetListForUser(@RequestParam("ldapId") String ldapId,
        final HttpServletRequest request){

Also, because I need the value if ldapId in the controller method, I am binding it in the calling method like this

     request.setAttribute("ldapId", assetAssetEmp.getAssetEmpId());

Please help.

Answer 1

It looks like your /recordList controller method only supports RequestMethod.POST . hence you're getting the 405 GET Method not allowed error, since the redirect will issue a GET request.

to solve for it, try to give a GET version of your controller action. (the assetlist method) so that once the update happens, the asset list of the user can be returned via the GET method.

The @RequestMapping annotation is your way to specify when your method is going to be called in an annotated controller. The RequestMethod.GET and RequestMethod.POST arguments allow you to respond to the specific HTTP request type.

providing method = RequestMethod.POST to controller method actually making method to accept only HTTP POST requests.
