Question

I’m trying to send parameters with PUT from JavaScript to a Spring application. Here is the @RequestMapping in a Spring Controller:

@RequestMapping(value = "toggle-paid-action", method = RequestMethod.PUT)
@ResponseBody
public final String togglePaid(@RequestParam final int year, 
    @RequestParam final String docType, @RequestParam final int number) {

And here the JavaScript snippet that is supposed to send those parameters.

Ext.Ajax.request({
    params: {year: year, docType: docType, number: number},
    url: 'toggle-paid-action',
    method: 'PUT',

However, I get a “400 Bad Request” every time with description “The request sent by the client was syntactically incorrect ()”.

If I check with Firebug, there is a PUT tab with all my parameters, and the parameters are correctly spelled since if I switch from PUT to POST on both sides everything works.

I was wondering what could be the problem, is PUT limited to @PathVariable parameters, or it can send also POST-like parameters?

Answer 1

I suppose you can’t pass parameters to spring using request method PUT as there is a restriction in the servlet API. You can only work with PUT methods implementing a restful service, passing data as the request body, in other cases (like Spring MVC Databinding) PUT won’t work.
see SpringMVC is not recognizing request body parameters if using PUT
