我想知道是否有人可以给我一些关于如何创建 Velocity 模板以循环浏览特定结构的 Web 内容项并根据特定结构字段的值呈现内容的想法/片段？

Here is a snippet from navigation.vm that will render group links:

#set($groupLocalService = $serviceLocator.findService("com.liferay.portal.service.GroupLocalService"))
#set($groupCount = $groupLocalService.getGroupsCount())
#set($groups = $groupLocalService.getGroups( 0, $groupCount))
<div id="community-links">
    <ul>
        #foreach ($group in $groups)
            #if ($group.community && $group.name != 'Guest' && $group.hasPublicLayouts())
                #set ($groupURL = $portletURLFactory.create($request, $group.name, $group.defaultPublicPlid, "ACTION_PHASE"))
                ${groupURL.setWindowState("normal")}
                ${groupURL.setPortletMode("view")}
                ${groupURL.setLifecycle("0")}
                ${groupURL.setParameter("groupId", ${group.getGroupId().toString()})}
                ${groupURL.setParameter("privateLayout", "false")}
                #if ($group.getGroupId() == $themeDisplay.getLayout().getGroup().getGroupId() )
                    #set ($className = "selected")
                #else
                    #set ($className = "unselected")
                #end
                <li class="${className}">                         
                    <a href="${groupURL.toString()}"><span>$group.getName()</span></a>
                </li> 
            #end
        #end    
    </ul>
</div>
