<ul class="nav nav-list">
        <#list permission as perm>
            <li>
                <a id="" href="#" target="_blank" rel="external nofollow"  class="dropdown-toggle tooltip-success" data-rel="tooltip"
                   data-placement="right" title="${perm.menuName}">
                    <i class="${perm.icon}"></i>
                    <span class="menu-text">${perm.menuName} </span>
                </a>
                <b class="arrow"></b>
                <ul class="submenu">
                    <#if perm.childrens??>
                        <#list perm.childrens as child>
                            <li id="${child.no}" class="">
                                <a href="${child.menuUrl}" target="_blank" rel="external nofollow"  class="tooltip-success" data-rel="tooltip"
                                data-placement="right" title="${child.menuName}">
                                    <i class="${child.icon}"></i>
                                    <span>${child.menuName}</span>
                                </a>
                                <b class="arrow"></b>
                            </li>
                        </#list>

                    </#if>
                </ul>
            </li>
        </#list>
    </ul><!-- /.nav-list -->
           

上面的代码为集成cas单点登录后在session中获取permission对象，利用freemarker指令遍历这个对象，动态加载菜单栏。
