我将 Web 内容嵌入到部署到 Liferay EE 6.1 GA 1 的自定义 portlet 中，使用：

<liferay-ui:journal-article   articleId="REMEMBER"  groupId="<%=portletGroupId%>" />

此错误开始显示在日志中，并且 Web 内容不存在：

请参考以下网址： http ://www.liferay.com/community/wiki/-/wiki/Main/Liferay+UI+Taglib

期刊文章参数：

articleId = uniqueID of content article
groupId = group of user
showTitle = show title of article true or false
templateId = which of the defined templates for this journal article to use. Note that there is a bug (reported here) in liferay versions before 6.0.2 where templateId is ignored.

示例：< liferay-ui:journal-article articleId="22745" groupId="<%=scopeGroupId%>" />

一件事似乎有帮助。更新了 WEB-INF/liferay-plugin-package.properties 以包含以下行：

portal.dependency.jars=commons-logging.jar,commons-fileupload.jar

来自https://www.liferay.com/community/wiki/-/wiki/Main/Liferay+Developer+Cookbook：

如果 portal\WEB-INF\lib 中已经存在任何 jar 文件，并且您还想在插件中使用它们。不要再次打包这些罐子，只需将引用添加到 docroot\WEB-INF\liferay-plugin-package.properties.

史密斯，我已经创建了自定义 portlet，并在下面的 jsp 中添加了一个 web 内容是代码，也在 plugin-package.properties 中我添加了所有在 JSP 页面中使用的 tld 文件，并且没有在属性中添加任何 jar 文件文件。

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<%@ taglib uri="http://liferay.com/tld/theme" prefix="liferay-theme" %>
<%@ taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui" %>
<portlet:defineObjects />
<liferay-theme:defineObjects/>

<liferay-ui:journal-article articleId="11414" articleResourcePrimKey="11416" groupId="<%=themeDisplay.getScopeGroupId() %>" languageId="<%=themeDisplay.getLanguageId() %>" showAvailableLocales="<%=true %>" ></liferay-ui:journal-article>

我使用了最新版本的 liferay 6.1.1 EE GA2，但我已经通过 LR6.1 EE GA1 对其进行了验证，它在那里也可以正常工作。
