Liferay PortalUtil.getPlidFromPortletId不工作

Question

我正在尝试创建一个从一个portlet到另一个portlet的链接，这两个portlet位于不同的页面中。注意，这两个页面确实存在于同一捆绑包中。

我在Liferay 6.x中广泛使用了这一点，但相同的代码在Liferay 7.3.4中不起作用。

我用来生成这个链接的代码如下：

<%@ 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中可以找到以下依赖项：

生成的页面如下所示，展示了PortalUtil.getPlidFromPortletId的无效结果：

myThemeId: 20122
orgCreatePlid: 0
orgCreatePortletName: com_xyz_portal_masterdata_organization_OrganizationCreatePortlet

对于PortalUtil.getPlidFromPortletId()，我得到的结果是零，这不应该是这种情况。

同样，这在我之前用Liferay6.2构建的项目中工作得很好。我没有在Liferay 7.3.4上获得同样的成功。

我很好奇是否有人遇到过类似的问题。

谢谢，兰迪

好吧，我想通了。下面的相关问题对我们有一点帮助：

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

本期讨论了使用getPlidFromPortletId处理特定页面类型的问题，例如全页面应用程序。

经过一些试验后，很明显，getPlidFromPortletId不适用于内容页面中嵌入的portlets，但可以很好地适用于Widget Page中嵌入的portlets。

我不确定这是不是一个bug。但是那些希望使用getPlidFromPortletId的人应该使用Widget页面。
