在使用foreach标签之前,需要在JSP中导入标签

<table align="center" width="98%" border="0" cellspacing="1" cellpadding="0" class="resulttable">
    <tr>
        <th width="18%">卡种类型</th>
        <th width="82%">卡种等级</th>
    </tr>
    <c:if test="${ empty command.cardList}">
        <tr><td align="center" colspan="10" class="oddbgc" >无记录</td>
        </tr>
    </c:if>             
    <c:if test="${ not empty command.cardList}">
        <c:forEach  var="bean" items="${ command.cardList}" varStatus="s">
            <c:if test="${bean.dataLevel=='1'}">
            <tr>
                <td align="left" class="<c:choose ><c:when test='${s.index%2 ==0}'>oddbgc</c:when><c:otherwise>evenbgc</c:otherwise></c:choose>"> 
                    <c:out value="${bean.cardName}"/>
                </td>
                <td align="left" class="<c:choose ><c:when test='${s.index%2 ==0}'>oddbgc</c:when><c:otherwise>evenbgc</c:otherwise></c:choose>">
                <c:forEach  var="childbean" items="${ command.cardList}" varStatus="sr">
                <c:if test="${bean.cardCode eq childbean.parentCardCode}">
                <c:out value="${childbean.cardName}"/>
                </c:if>
                </c:forEach>
                </td>
            </tr>
            </c:if>
        </c:forEach>
    </c:if> 
</table>

jsp页面itertor或forEach循环输出list:

JSP遍历后台传过来的List(总结的比较好):
三种方法:使用jstl标签
使用jsp内嵌Java代码遍历list(在后台把list放到session中)
使用struts标签
