如何将数据从Json转换为java
如何将数据从Json转换为java
提问于 2018-07-27 04:57:20
我正在尝试通过Ajax调用在JSP页面中获取开始日期，但它作为Json对象返回，即153452636268，我想将我的日期从JSon转换为Java，你能帮助我吗？
$.ajax({
type: "GET",
url: "${pageContext.request.contextPath}" + "/status/id?city="+city,
async: false,
cache : false,
contentType: "application/json",
success: function (response) {
var $tab = $("#Table");
$tab.css("display", "inline");
$.each(response.statusId, function(index,statusDetail) {
$tab.append("<tr><td align='center'><input id='Radio"+index+"' name='statRadio' title='"+index+"' type='radio'/></td>"+
"<td id='productId"+index+"' align='center' style='display: none;'>"+statusDetail.key.StudId+"</td>"+
"<td id='startDate"+index+"' align='center'>"+statusDetail.key.startDate+"</td></tr>");
//
});
},
failure: function (response) {
return;
},
error: function (response) {
return;
}
});回答 3

如果您有一个带有毫秒的变量，则可以将其提供给Date构造函数来创建Date对象，您可以根据需要使用和操作该对象。
var milliseconds = 1532318400000;
//whatever variable holds your timestamp
var turnItIntoADate = new Date(milliseconds);
console.log(turnItIntoADate.toString());
但我想强调的是，所有这些都不是Java。这都是Javascript。
如果需要以特定的方式格式化日期，可以看到相关的问题：How to format a JavaScript date

System.out.println("current Date: " + currentDate);
DateFormat df = new SimpleDateFormat("dd:MM:yy:HH:mm:ss");
//formatted value of current Date
System.out.println("Milliseconds to Date: " + df.format(currentDate));
//Converting milliseconds to Date using Calendar
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(currentDateTime);
System.out.println("Milliseconds to Date using Calendar:"
+ df.format(cal.getTime()));
//copying one Date's value into another Date in Java
Date now = new Date();
System.out.println("original Date: " + df.format(now));
}
}希望这能对你有所帮助。

In JSP page. You can use JSP Tag library.
<jsp:useBean id="dateObject" class="java.util.Date" /> <jsp:setProperty name="dateObject" property="time" value="${timeInMilliSeconds}" />
Date is :
<b><fmt:formatDate value="${dateObject }" pattern="dd/MM/yyyy"><b>
Time is :
<b><fmt:formatDate value="${dateObject }" pattern="hh:mm a" /></b>
output:
Date is : 26/02/2018 Time is : 06:27 PM页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
