Liferay PortalUtil.getPlidFromPortletId不起作用

编程问答 2022-06-13

问题描述

我正在尝试创建从一个Portlet到另一个Portlet的链接，其中两个Portlet位于不同的页面中。请注意，这两个页面确实存在于同一个包中。

我已经在Liferay 6.x中广泛使用了此功能，但是相同的代码在Liferay 7.3.4中不起作用。

我用来生成此链接的代码如下：

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet"%>

<%@ taglib uri="http://liferay.com/tld/aui" prefix="aui"%>
<%@ taglib uri="http://liferay.com/tld/frontend" prefix="liferay-frontend"%>
<%@ taglib uri="http://liferay.com/tld/portlet" prefix="liferay-portlet"%>
<%@ taglib uri="http://liferay.com/tld/theme" prefix="liferay-theme"%>
<%@ taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui"%>
<%@ taglib uri="http://liferay.com/tld/util" prefix="liferay-util"%>

<liferay-theme:defineObjects />
<portlet:defineObjects />

<%
    long myThemeId = themedisplay.getScopeGroupId();
    String orgCreatePortletName = com.xyz.portal.masterdata.organization.constants.OrganizationPortletKeys.OrganizationCreate;
    long orgCreatePlid = com.liferay.portal.kernel.util.PortalUtil.getPlidFromPortletId(myThemeId,orgCreatePortletName);
%>

<br />
myThemeId: <%=myThemeId%>
<br />
orgCreatePlid: <%=orgCreatePlid%>
<br />
orgCreatePortletName: <%=orgCreatePortletName%>
<br />

我要生成链接的页面的组件声明如下：

@Component(immediate = true,property = {
        "com.liferay.portlet.display-category=" + OrganizationPortletKeys.OrganizationCategory,"com.liferay.portlet.header-portlet-css=/css/main.css","com.liferay.portlet.instanceable=true","javax.portlet.display-name=Organization - Create","javax.portlet.init-param.template-path=/","javax.portlet.init-param.view-template=/organizationCreate/view.jsp","javax.portlet.init-param.copy-request-parameters=true","javax.portlet.name=" + OrganizationPortletKeys.OrganizationCreate,"javax.portlet.resource-bundle=content.Language","javax.portlet.security-role-ref=power-user,user"
},service = Portlet.class)
public class OrganizationCreatePortlet extends MVCPortlet

Liferay项目是使用Maven构建的，在pom.xml中具有以下依赖项：

生成的页面如下，表明PortalUtil.getPlidFromPortletId的结果无效：

myThemeId: 20122
orgCreatePlid: 0
orgCreatePortletName: com_xyz_portal_masterdata_organization_OrganizationCreatePortlet

我为PortalUtil.getPlidFromPortletId（）获得的结果为零，情况并非如此。

同样，这在以前使用Liferay 6.2构建的项目中也能正常工作。 Liferay 7.3.4无法获得同样的成功。

好奇是否有人遇到过类似问题。

谢谢， 兰迪

解决方法

好的，我知道了。以下相关问题有所帮助：

https://issues.liferay.com/browse/LPS-74443?page=com.atlassian.streams.streams-jira-plugin%3Aactivity-stream-issue-tab

此问题讨论了getPlidFromPortletId适用于特定页面类型（例如整页应用程序）的问题。

经过一些试验，很明显，getPlidFromPortletId不适用于内容页面中嵌入的portlet，但是对于嵌入在小部件页面中的portlet很好。

我不确定这是否是错误。但是，那些希望使用getPlidFromPortletId的用户应该使用小部件页面。
