java - Liferay portlet 配置

Question

我正在尝试个性化 Liferay portlet 的配置。

configuration.jsp 是:

<%@include file="/init.jsp" %>

<liferay-portlet:actionURL portletConfiguration="true" var="configurationURL" />

<%
boolean showLocationAddress_cfg = GetterUtil.getBoolean(portletPreferences.getValue("showLocationAddress", StringPool.TRUE));
%>

<aui:form action="<%= configurationURL %>" method="post" name="fm">
    <aui:input name="<%= Constants.CMD %>" type="hidden" value="<%= Constants.UPDATE %>" />

    <aui:input  name="preferences--showLocationAddress--" type="checkbox" value="<%= showLocationAddress_cfg %>" />
    <aui:input key="mailAddress" type="text" name="preferences--mailAddress--"/>
    <aui:button-row>
       <aui:button name="save-Boutton" type="submit" value="Save"/>
    </aui:button-row>
</aui:form>

ConfigurationActionImpl.java 是:

package com.nosester.portlet.eventlisting.action;

import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.PortletConfig;
import javax.portlet.PortletPreferences;

import com.liferay.portal.kernel.portlet.DefaultConfigurationAction;
import com.liferay.portal.kernel.servlet.SessionErrors;
import com.liferay.portal.kernel.servlet.SessionMessages;
import com.liferay.portal.kernel.util.Constants;
import com.liferay.portal.kernel.util.ParamUtil;
import com.liferay.portlet.PortletPreferencesFactoryUtil;

    public class ConfigurationActionImpl extends DefaultConfigurationAction {

        @Override
        public void processAction(
            PortletConfig portletConfig, ActionRequest actionRequest,
            ActionResponse actionResponse) throws Exception {

            super.processAction(portletConfig, actionRequest, actionResponse);

           PortletPreferences prefs = actionRequest.getPreferences();


            String mailAddress=prefs.getValue("mailAddress", "default");


           System.out.println("address mail= "+mailAddress);
        }

但在所有情况下显示的邮件地址都是:默认。

有人可以帮助我更正此代码，以便它可以显示用户在文本字段中输入的内容吗？

我相信，当您调用 DefaultConfigurationAction 的 processAction 方法时，actionRequest 并未使用 portletPreferences 值进行更新。您可以使用下面的代码来正确获取它。

 String portletResource = ParamUtil.getString(
        actionRequest, "portletResource");

 PortletPreferences portletPreferences =
        PortletPreferencesFactoryUtil.getPortletSetup(
            actionRequest, portletResource);

 portletPreferences .getValue("mailAddress", "default");
