Liferay Freemarker - 如何在内容模板中获取标签
Liferay Freemarker - How to get tags in a Content Template
我有一个包含结构和模板的内容,我想访问内容的标签以在模板中显示它。
在以前的资产发布者的应用程序显示模板中,我得到了带有 ServiceLocator 的标签,如下所示:
<#list entries as entry>
<#assign assetEntryLocalService = serviceLocator.findService("com.liferay.portlet.asset.service.AssetEntryLocalService") />
<#assign assetTagLocalService = serviceLocator.findService("com.liferay.portlet.asset.service.AssetTagLocalService") />
<#assign assetTags = assetTagLocalService.getEntryTags(entry.getEntryId()) />
<#list assetTags as tag>
<#if tag.getName() != "startseite">
${tag.getName()}
</#if>
</#list>
</#list>
在我的模板中,我将条目与 .vars['reserved-article-id'].data
交换,但随后出现错误:
Method public final java.util.List com.sun.proxy.$Proxy562.getEntryTags(long) throws com.liferay.portal.kernel.exception.SystemException threw an exception when invoked on com.liferay.portlet.asset.service.impl.AssetTagLocalServiceImpl@6bc73e2b
你如何让它在模板中工作?
标签使用它的 resourcePrimKey 与 assetEntry 相关联,因此您可以这样做:
<#assign assetEntryLocalService = serviceLocator.findService("com.liferay.portlet.asset.service.AssetEntryLocalService") />
<#assign journalArticleLocalService = serviceLocator.findService("com.liferay.portlet.journal.service.JournalArticleLocalService") />
<#assign article = journalArticleLocalService.getArticle(getterUtil.getLong(scopeGroupId), .vars['reserved-article-id'].data)>
<#assign asset = assetEntryLocalService.getEntry('com.liferay.portlet.journal.model.JournalArticle', article.resourcePrimKey) >
<#list asset.getTags() as tag>
<code>${tag.name}</code>
</#list>
从 Liferay 7 开始,您应该可以使用以下内容:
<#list entries as entry>
<#assign
entry = entry
/>
<#list entry.tagNames as tag>
${tag}
</#list>
</#list>
