时间比较

后台：

//创建实例

Calendar currentTime = Calendar.getInstance();
Calendar compareTime = Calendar.getInstance();
currentTime.setTime(new Date());
compareTime.setTime(sponsorOrganizerNotices.get(0).getEvaluateEndTime());
//加一天

compareTime.add(Calendar.DATE, +1);
if (currentTime.compareTo(compareTime) < 0) {

//前面时间小于后面时间
    
}

前台获取服务器时间：

<script type="text/javascript">
    $.ajax({
        type:"OPTIONS",
        async:false,
        url:"/",
        complete:function(x){
            //alert(getLocalDate(x.getResponseHeader("Date")))
            window.serverDate =new Date(getLocalDate(x.getResponseHeader("Date")));
        }
    })

</script>

var endDate = new Date(dataArr[1]);
endDate.setDate(endDate.getDate()+1);//时间+1天

if(serverDate<endDate) {

//前面时间等于或小于当前时间

}
