我设法重新请求删除

 @RequestMapping(value = "cancelUpload", produces="text/html" method = RequestMethod.DELETE)

但要用

$.ajax({  
            url: 'additions/cancelUpload',  
            type: 'POST',  
            data: {filename : ui.draggable.get(0).file.name, _method: 'DELETE'},  
            success: function (res) {  
                alert(res);
            }  
        }); 

您可以在http://blog.springsource.org/2009/03/08/rest-in-spring-3-mvc/中阅读post请求的_method:'delete'参数
