对于Freemarker 来说，宏就相当于函数，其定义了签名及参数列表。
所以在freemarker页面应这样写：
<#macro menuTree menus>
<#if menus?? && menus?size gt 0>
<#list menus as menu>
<tr>
<td>
<input type="checkbox" name="ids" value="${menu.id}" />
</td>
<td>
<span title="${menu.name!}" style="margin-left: ${menu.leaf * 30}px;[#if menu.leaf == 0] color: #000000;[/#if]">
${menu.menuName!}
</span>
</td>
<td>
${menu.url!}
</td>
<td>
${menu.permissionText!}
</td>
<td>
${menu.sortNo!}
</td>
<td>
<a href="edit.jhtml?id=${menu.id}">[编辑]</a>
</td>
</tr>
<#if menu.menuBeans?? && menu.menuBeans?size gt 0>
<@menuTree menus = menu.menuBeans/>
</#if>
</#list>
</#if>
</#macro>
<!-- 调用宏 生成递归树 -->
<@menuTree menus = dto />后台数据：
