java - 公司范围的首选项设置在 Liferay 中不起作用

Question

我创建了 2 个测试 portlet:myportlet1 和 myportlet2。两个描述都很相似，在 portlet.xml

中看起来像这样

<portlet>
    <portlet-name>myportlet1</portlet-name>
    <display-name>MyPortlet1</display-name>
    <portlet-class>com.inthemoon.tests.MyPortlet1</portlet-class>
    <init-param>
        <name>view-jsp</name>
        <value>/html/myportlet1/view.jsp</value>
    </init-param>
    <expiration-cache>0</expiration-cache>
    <supports>
        <mime-type>text/html</mime-type>
        <portlet-mode>VIEW</portlet-mode>
    </supports>
    <portlet-info>
        <title>MyPortlet1</title>
        <short-title>MyPortlet1</short-title>
        <keywords></keywords>
    </portlet-info>
    <portlet-preferences>
        <preference>
            <name>testPreferenceForMyPortlet1</name>
            <value>C:\WINDOWS1</value>
        </preference>
    </portlet-preferences>
    <security-role-ref>
        <role-name>administrator</role-name>
    </security-role-ref>
    <security-role-ref>
        <role-name>guest</role-name>
    </security-role-ref>
    <security-role-ref>
        <role-name>power-user</role-name>
    </security-role-ref>
    <security-role-ref>
        <role-name>user</role-name>
    </security-role-ref>
</portlet>

就像这样在liferay-portlet.xml

<portlet>
    <portlet-name>myportlet1</portlet-name>
    <icon>/icon.png</icon>
    <preferences-company-wide>true</preferences-company-wide>
    <instanceable>false</instanceable>
    <header-portlet-css>/css/main.css</header-portlet-css>
    <footer-portlet-javascript>
        /js/main.js
    </footer-portlet-javascript>
    <css-class-wrapper>myportlet1-portlet</css-class-wrapper>
</portlet>

区别在于索引。

因此，如您所见，这两个 portlet 都不可实例化，并且设置为在公司范围内共享其首选项。

不过，下面的代码表明每个 portlet 只知道它自己的首选项，而不知道其他 portlet 的首选项:

@Override
public void doView(RenderRequest renderRequest,
        RenderResponse renderResponse) throws IOException, PortletException {

    javax.portlet.PortletPreferences prefs1 = renderRequest.getPreferences();
    //com.liferay.portal.model.PortletPreferences prefs2 = PortletPreferencesLocalServiceUtil.

    String portletResource = ParamUtil.getString(renderRequest, "portletResource");
    if (Validator.isNotNull(portletResource)) {
        try {
            prefs1 = PortletPreferencesFactoryUtil.getPortletSetup(renderRequest, portletResource);
        } catch (SystemException e) {
            e.printStackTrace();
        }
    }

    String testPreferenceForMyPortlet1 = prefs1.getValue("testPreferenceForMyPortlet1", "(not set)");
    String testPreferenceForMyPortlet2 = prefs1.getValue("testPreferenceForMyPortlet2", "(not set)");

    renderRequest.setAttribute("testPreferenceForMyPortlet1", testPreferenceForMyPortlet1);
    renderRequest.setAttribute("testPreferenceForMyPortlet2", testPreferenceForMyPortlet2);

    renderRequest.setAttribute("prefs1", prefs1);

    super.doView(renderRequest, renderResponse);
}

我做错了什么？谢谢

“问题”是 preferences-company-wide 没有告知首选项将与不同的 portlet 共享。

它的用途是在单个 portlet 内但在不同的社区/组织/user_pages ...(不同的组 ID)中共享首选项。

要获取另一个 portlet 的首选项，您必须使用

PortletPreferencesFactoryUtil.getPortletSetup(portletRequest, "another portlet's id");
