Spring And ExtJS "400 Bad Request" With PUT But Not With POST

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', me

Solution 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

Solution 2:

This, as suggest above, seems to be a bug in spring/servlet API. In reality PUT requests are supposed to work on Request Body (or payload) and not on Request Parameters. In that sense, servlet API & spring's handling is correct.

Having said that, a better and much easier workaround is to pass no data element from your javascript/jQuery call and pass your parameters as part of the url itself. meaning, set parameters in the url field the way you would do in a GET call.

$.ajax({
            url: "yoururl" + "?param1=param2Val&..",
            type: "PUT",
            data: "",
            success: function(response) {
                // ....
            }
     });

now this works for simple parameters, i guess, will not work for complex JSON types. Hope this helps.
