如何在jsp页面上将int值转换为字符串 [英] How to convert int value into string on jsp page

问题描述

我有一个包含Map的地图，我使用

I have a map that contains Map , which i iterate it on jsp page using

    <c:forEach var="schoolDetails" items="${schoolCodeIdMap}"> 
                                                  //below i am getting value from another map which contains String as a key.     
    <c:set var="smsStatsCalendar" value="${smsStats.get(schoolDetails.value)}"></c:set>

<c:foreach>

在上面的代码中，smsStats包含String作为键，并且我正在传递Integer Value以获取对象.我如何将那个schoolDetails.value(int)值转换为字符串以获取对象.

In above code smsStats contains String as key and I am passing Integer Value to get object. How can i convert That schoolDetails.value (int) value into string to get object.

推荐答案

您可以使用c:set将其设置为另一个变量，该变量应为您执行隐式字符串转换:

You could set it to another variable using c:set, which should do implicit String conversion for you:

<c:forEach var="schoolDetails" items="${schoolCodeIdMap}"> 
    <c:set var="detailValue">${schoolDetails.value}</c:set>
    <c:set var="smsStatsCalendar" value="${smsStats.get(detailValue)}"/>
<c:foreach>

c:set标记的主体将始终被解释为纯文本，因此该标记会将其转换为String变量.这与使用:

The body of a c:set tag will always be interpretted as plain text, and so get converted to a String variable by the tag. This is in contrast to using:

<c:set var="detailValue" value="${schoolDetails.value}"/>

将属性类型保持为整数.

which would maintain the property type as an integer.
