Java解决LocalDateTime传输前端为时间的数组

        ,cols: [[ //表头
            {type: 'checkbox', fixed: 'left'}
            ,{field: 'purchaseId', title: 'ID',  sort: true, fixed: 'left',hide:true}
            ,{field: 'supplierName', title: '供应商名称',sort: true}//当field是直属属性时，可以不用temple去获取！
            ,{field: 'userName', title: '采购员', sort: true}
            ,{field: 'purchaseDate', title: '采购时间',sort: true,templet:function(resp){
                return dateArrayTransfer(resp.purchaseDate,'yyyy-MM-dd HH:mm:ss');
                }}
            ,{fixed:'right',title:'操作',toolbar:'#operatBtn'}



function dateArrayTransfer(dateArray) {
    if(dateArray == null || dateArray == ''){
        return '';
    }
    var returnDate = dateArray[0]+"-"+
        returnDoubleNum(dateArray[1])+"-"+
        returnDoubleNum(dateArray[2])+" "+
        returnDoubleNum(dateArray[3])+":"+
        returnDoubleNum(dateArray[4])+":"+
        returnDoubleNum(dateArray[5]);
    return returnDate;
}
//保证两位数
function returnDoubleNum(number) {
    return (Array(2).join(0) + number).slice(-2);//创建一个长度为2的数组，且默认用0填充；然后用传过来的数添加都右边，然后从右向左截取两位！
