如何使用jstl在jsp的日历类型方法中获取日期设置?

问题描述：

我正在使用执行查询

select lastlevel as VERSION,name as DESCRIPTION,
TO_DATE(lastdate, 'DDMONYYYY_HH24:MI:SS') as RELEASEDATE
from mytable where rownum<=10

此处lastdate列为varchar类型

here the column lastdate is of varchar type

给出这样的结果

Version     Release Date        
1.0         2002-11-22

2.0     2003-02-08

我正在像这样设置以上查询的结果这里的setLastDate是日历类型，所以我用

i am setting the result of the above query like this here setLastDate is of calender type,so i am setting the result of release date in the method like

if (rs.getString("VERSION") != null ) {             bean.setLastLevel(rs.getString("VERSION").trim());
}

if (rs.getDate("RELEASEDATE") != null ) 
{
Calendar calendar = Calendar.getInstance();
calendar.setTime(rs.getDate("RELEASEDATE"));
bean.setLastDate(calendar);
}

正在像2003-02-08这样在bean中设置值. 最后，我将此结果bean添加到数组列表列表"中，例如 list.add(bean);

the value is being set in the bean like this 2003-02-08. at the end i am adding this result bean to an array list "list" like list.add(bean);

现在我希望在jsp中使用所有这些值.我正在使用spring mvc，所以我用arraylist"list"返回视图. 当我迭代jsp中的值时像这样

now i want all this value in jsp. I am using spring mvc so i return view with the arraylist "list". when i am iterating the value in jsp like this

<c:forEach var="list" items="${list}">
<td valign="top">${list.lastLevel}</td>
<td valign="top">${list.lastDate}</td>
</c:forEach>

在jsp中，我没有得到日期，就像这样

in jsp instead of getting date i am getting like this

Version     Release Date        
1.0          java.util.GregorianCalendar[time=1037775600000,areFieldsSet=true,

areAllFieldsSet = true，lenient = true，zone = sun.util.calendar.ZoneInfo [id ="US/Arizona"，offset = -25200000，dstSavings = 0，useDaylight = false，transitions = 12，lastRule = null] ，firstDayOfWeek = 1，minimumDaysInFirstWeek = 1，ERA = 1，YEAR = 2002，MONTH = 10，WEEK_OF_YEAR = 47，WEEK_OF_MONTH = 4，DAY_OF_MONTH = 20，DAY_OF_YEAR = 324，DAY_OF_WEEK = 4，DAY_OF_WEEK_IN_MONTH = 3，AM_PM = 0 = 0，HOUR_OF_DAY = 0，MINUTE = 0，SECOND = 0，MILLISECOND = 0，ZONE_OFFSET = -25200000，DST_OFFSET = 0]

areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="US/Arizona",offset=-25200000,dstSavings=0,useDaylight=false,transitions=12,lastRule=null],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2002,MONTH=10,WEEK_OF_YEAR=47,WEEK_OF_MONTH=4,DAY_OF_MONTH=20,DAY_OF_YEAR=324,DAY_OF_WEEK=4,DAY_OF_WEEK_IN_MONTH=3,AM_PM=0,HOUR=0,HOUR_OF_DAY=0,MINUTE=0,SECOND=0,MILLISECOND=0,ZONE_OFFSET=-25200000,DST_OFFSET=0]

2.0          java.util.GregorianCalendar[time=1044687600000,areFieldsSet=true,
areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="US/Arizona",offset=-25200000,dstSavings=0,useDaylight=false,transitions=12,lastRule=null],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2003,MONTH=1,WEEK_OF_YEAR=6,WEEK_OF_MONTH=2,DAY_OF_MONTH=8,DAY_OF_YEAR=39,DAY_OF_WEEK=7,DAY_OF_WEEK_IN_MONTH=2,AM_PM=0,HOUR=0,HOUR_OF_DAY=0,MINUTE=0,SECOND=0,MILLISECOND=0,ZONE_OFFSET=-25200000,DST_OFFSET=0]

请帮助我解决这个问题.我需要得到结果的日期.如何解决这个问题. 预先感谢.

please help me in solving this.I need to get the date as in result.How to resolve this. Thanks in advance.

答

使用

<td valign="top">${list.lastDate.time}</td>

它将在日历实例上调用getTime()方法，该方法返回Date实例

It will call getTime() method on calendar instance which returns the Date instance

最好不要使用与属性相同的var名称，而是将其命名为row(或其他有意义的变量名)，然后再命名为${row.lastDate.time}

It is preferable not to use same var name as the attribute, call it row (or someother sensible variable name) instead and then ${row.lastDate.time}

<c:forEach var="row" items="${list}">
</c:forEach>

如果要自定义格式输出，则

if you want the custom format output then

添加

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

并像使用它

<fmt:formatDate pattern="yyyy-MM-dd"  value="${list.lastDate.time}" />
