jquery1.4.2 ajax 中文乱码问题解决方案

前端ajax用POST方式： $.ajax({                type : "POST",                url : "**/save.do",                async : true,                dataType : "json",                data : "data=中文",                success : function(resp) {                    alert(resp.cr); //必须严格按照JSON的标准来                },                error : function() {                    alert('数据保存失败！');                }            });后台直接接收data参数即可：      @RequestMapping(value = "**/save.do", method = RequestMethod.POST)    public void saveBeizhu( @RequestParam(value = "data", required = false) String data,            HttpServletRequest request, HttpServletResponse response) throws Exception{        request.setCharacterEncoding("UTF-8");        log.error(data);        response.setCharacterEncoding("utf-8");        response.setContentType("text/html;charset=utf-8");        response.getWriter().print("{\"cr\":\"保存成功！\"}");    }
