菜单权限管理

MAP集合key  value   应用

<div class="accordion" fillSpace="sidebar">
<c:forEach var="setting" items="${settings}">
<div class="accordionHeader">
<h2>
<span>Folder</span>${setting.key.resourcename}
</h2>
</div>
<div class="accordionContent">
<c:forEach var="sr" items="${setting.value}">

<ul class="tree">
<li><a href="${ctx}/${sr.key.url}" target="navTab" rel="${sr.key.rel}" <c:if test="${sr.key.isExist==1}">checked="true" </c:if>>${sr.key.resourcename}</a>

<c:forEach var="thr" items="${sr.value}">
<ul>
<li><a href="${ctx}/${thr.url}" target="navTab" rel="${thr.rel}" <c:if test="${r.isExist==1}">checked="true" </c:if>>${thr.resourcename}</a></li>
</ul>
</c:forEach>
</li>
</ul>
</c:forEach>
</div>
</c:forEach>
</div>
