SpringMVC is not recognizing request body parameters if using PUT

Question

Maybe this is supposed to not work, but at least I\'d like to understand why then. I am passing a simple val=somevalue in the PUT body but spring sends back a <

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.
