Spring @RequestParam arguments not being passed in POST method

Question

I\'m having a problem with Spring and a post request. I\'m setting up an controller method for an Ajax call, see the method definition below

@RequestMapping         


        

Answer 1

The problem turned out to be the way I was calling the method. My ajax code was passing all the parameters in the request body and not as request parameters, so that's why my @RequestParam parameters were all empty. I changed my ajax code to:

$.ajax({
    type: 'POST',
    url: "/comments/add.page?uuid=${param.uuid}&type=${param.type}",
    data: text,
    success: function (data) {
        //
    }
});

I also changed my controller method to take the text from the request body:

@RequestMapping(value = "add.page", method = RequestMethod.POST)
@ResponseBody
public Object createComment(
        @RequestParam(value = "uuid", required = false) String entityUuid,
        @RequestParam(value = "type", required = false) String entityType,
        @RequestBody String text,
        HttpServletResponse response) {

And now I'm getting the parameters as I expect.
