AJAX+RESTFUL风格无法封装请求数据的原因?

[ZzwCoder]

代码:

 //2.发送ajax请求保存更新的员工数据
        $.ajax({
            //获取到当前按钮的<员工id>属性方便拼接restful{id}请求
            <%--url: "${path}/emp/" + $(this).attr("edit-id"),--%>
            <%--type: "PUT",--%>
            url: "${path}/update/"+$(this).attr("edit-id"),
            type: "PUT",
            date: $("#empUpdateModal form").serialize(),
            dataType:"json",
            success: function (result) {
                alert(result.msg);
                // 1.关闭对话框
                $("#empUpdateModal").modal("hide");
                // 回到当前页面
                to_Page(currentPage);
            }
        });

 @ResponseBody
    @RequestMapping(value = "/update/{empId}",method = RequestMethod.PUT)
    public Msg UpdateEmp(Employee employee,HttpServletRequest request) {
        System.out.println("请求体中的值:" + request.getParameter("gender"));
        System.out.println("将要更新的员工数据:" + employee);
        employeeService.updateEmp(employee);
        return Msg.success();
    }

 <filter>
        <filter-name>HiddenHttpMethodFilter</filter-name>
        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>HiddenHttpMethodFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <filter>
        <filter-name>HttpPutFormContentFilter</filter-name>
        <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>HttpPutFormContentFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

困扰:
无论是直接发PUT请求还是POST请求都无法获取和封装请求参数到,只能获取到请求路径中的empId

[jio可]

date => data ajax options 字段敲错了
