Question

我有一个Calendar对象，我正在尝试将其传递给JSP并使用JSTL格式化为我自己的自定义格式：

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

<c:forEach items="${employees}" var="employee" varStatus="loop">
                <fmt:parseDate value="${employee.startDate}" var="parsedStartDate" pattern="HH:mm dd/MM/yyyy z" />
                <fmt:parseDate value="${employee.endDate}" var="parsedEndDate" pattern="HH:mm dd/MM/yyyy z" />
                var contentString = '<div id="content">' +
                        '<h1 id="firstHeading" class="firstHeading" style="font-size: 11px;"><p style="color: green">${parsedStartDate}</p> to <p style="color: orange">${parsedEndDate}</p></h1>' +
                        '<div id="bodyContent">' +
                        '<p style="font-size: 14px;">${employee.details}</p>' +
                        '</div>' +
                        '</div>';
</c:forEach>

employee对象是标准Calendar.getInstance();对象。

编辑，完全例外：

java.text.ParseException: Unparseable date: "java.util.GregorianCalendar[time=1417392000000,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="Europe/London",offset=0,dstSavings=3600000,useDaylight=true,transitions=242,lastRule=java.util.SimpleTimeZone[id=Europe/London,offset=0,dstSavings=3600000,useDaylight=true,startYear=0,startMode=2,startMonth=2,startDay=-1,startDayOfWeek=1,startTime=3600000,startTimeMode=2,endMode=2,endMonth=9,endDay=-1,endDayOfWeek=1,endTime=3600000,endTimeMode=2]],firstDayOfWeek=2,minimalDaysInFirstWeek=4,ERA=1,YEAR=2014,MONTH=11,WEEK_OF_YEAR=49,WEEK_OF_MONTH=1,DAY_OF_MONTH=1,DAY_OF_YEAR=335,DAY_OF_WEEK=2,DAY_OF_WEEK_IN_MONTH=1,AM_PM=0,HOUR=0,HOUR_OF_DAY=0,MINUTE=0,SECOND=0,MILLISECOND=0,ZONE_OFFSET=0,DST_OFFSET=0]"

at com.example.controller.EmployeeController.doGet(EmployeeController.java:48)是：request.getRequestDispatcher("/index.jsp").forward(request, response);

parseDate用于解析字符串输入并转换为Date对象。你不应该使用parseDate。而是使用formatDate

<c:forEach items="${employees}" var="employee" varStatus="loop">
   var contentString = '<div id="content">' +
     '<h1 id="firstHeading" class="firstHeading" style="font-size: 11px;"><p style="color: green">
    <fmt:formatDate type="time" value="${employee.startDate.time}" pattern="HH:mm dd/MM/yyyy z"/></p> to <p style="color: orange">
    <fmt:formatDate type="time" value="${employee.endDate.time}" pattern="HH:mm dd/MM/yyyy z" /></p></h1>' +
    '<div id="bodyContent">' +
    '<p style="font-size: 14px;">${employee.details}</p>' +
    '</div>' +
    '</div>';
</c:forEach>

javax.servlet.ServletException：javax.servlet.jsp.JspException：在＆lt; parseDate＆gt;中，无法解析value属性
