前端form表单中datetime类型数据传到后台

前端jsp页面用EasyUI写了个form表单，要传到后台的数据里面有个date和datetime格式的，后台直接用对象接收的，所以需要对datetime格式的数据进行处理。

js部分代码：

    //把字符串转为日期
    function dateFormat(stringTypeDate){
        var dateType = "";
        var date = new Date(stringTypeDate);
        dateType = date.getFullYear()+"-"+getMonth(date)+"-"+getDay(date);
        return dateType;
    }
    function datetimeFormat(stringTypeDate){  
        var datetimeType = "";  
        var date = new Date(stringTypeDate);  
        datetimeType = date.getFullYear()+"-"+getMonth(date)+"-"+getDay(date)+" "+
        getHours(date)+":"+getMinutes(date)+":"+getSeconds(date);//yyyy-MM-dd 00:00:00格式日期
        return datetimeType;
    }
    //返回 01-12 的月份值   
    function getMonth(date){  
        var month = "";  
        month = date.getMonth() + 1; //getMonth()得到的月份是0-11  
        if(month<10){  
            month = "0" + month;  
        }  
        return month;  
    }  
    //返回01-30的日期  
    function getDay(date){  
        var day = "";  
        day = date.getDate();  
        if(day<10){  
            day = "0" + day;  
        }  
        return day;  
    }
    //返回小时
    function getHours(date){
        var hours = "";
        hours = date.getHours();
        if(hours<10){  
            hours = "0" + hours;  
        }  
        return hours;  
    }
    //返回分
    function getMinutes(date){
        var minute = "";
        minute = date.getMinutes();
        if(minute<10){  
            minute = "0" + minute;  
        }  
        return minute;  
    }
    //返回秒
    function getSeconds(date){
        var second = "";
        second = date.getSeconds();
        if(second<10){  
            second = "0" + second;  
        }  
        return second;  
    }
    $(function() {
        $("#add").click(function() {
            var client = {
                    "client_name": $('#client_name').val(),
                    "client_id": $('#client_id').val(),
                    "client_sex": $("input[name='client_sex']:checked").val(),
                    "client_birthday":dateFormat($('#client_birthday').datebox('getValue')),
                    "client_address": $('#client_address').val(),
                    "room_no": $('#room_no').val(),
                    "isVip": $("input[name='isVip']:checked").val(),
                    "check_in":datetimeFormat($('#check_in').datetimebox('getValue'))
                }
                console.log(client)
            $.post("../insertClient.action",client,function(flag){
                if("OK"==flag){
                    window.location.href="allRoomsInfo.jsp";
                }
            })
        })
    })

controller部分代码：

    @RequestMapping(value="insertClient")
    @ResponseBody
    public String insertClient(@Param("client") Client client) {
        //System.out.println(client);
        clientService.insertClient(client);
