用户通知处理程序：自定义通知处理程序在liferay 7.1中不起作用

Question

我们已经使用@component(service=UserNotificationHandler.class)创建了自定义通知处理程序，但是它不起作用。

用户通知处理程序代码

package com.alert.service.notification;

import com.liferay.petra.string.StringBundler;
import com.liferay.petra.string.StringUtil;
import com.liferay.portal.kernel.json.JSONFactoryUtil;
import com.liferay.portal.kernel.json.JSONObject;
import com.liferay.portal.kernel.model.UserNotificationEvent;
import com.liferay.portal.kernel.notifications.BaseUserNotificationHandler;
import com.liferay.portal.kernel.notifications.UserNotificationHandler;
import com.liferay.portal.kernel.service.ServiceContext;

import org.osgi.service.component.annotations.Component;

@Component(immediate=true, service= UserNotificationHandler.class)
public class NotificationHandler extends BaseUserNotificationHandler {

    public NotificationHandler() {
        setPortletId("travelportalertportlet_WAR_travelportalertportlet");
    }

    @Override
    protected String getBody(UserNotificationEvent userNotificationEvent, ServiceContext serviceContext)
            throws Exception {
        // TODO Auto-generated method stub
        JSONObject json=JSONFactoryUtil.createJSONObject(userNotificationEvent.getPayload());
        return com.liferay.portal.kernel.util.StringUtil.replace(getBodyTemplate(), new String[] {"[$TITLE$]","[$SENDERNAME$]","[$BODY_TEXT$]"}, new String[] {json.getString("title"),json.getString("senderName"),json.getString("notificationText")});
    }

    @Override
    protected String getBodyTemplate() throws Exception {
        // TODO Auto-generated method stub
        StringBundler s=new StringBundler(5);
        s.append("<div> [$TITLE$] <div>");
        s.append("<div> [$SENDERNAME$] <div>");
        return s.toString();
    }
}

呼叫用户通知

final NotificationEvent notificationEvent = NotificationEventFactoryUtil.createNotificationEvent(
                            System.currentTimeMillis(), portletKey, notificationEventJSONObject);

                    UserNotificationEventLocalServiceUtil.addUserNotificationEvent(userId, notificationEvent);

->获取上一行的输出，但是通知未保存在usernotificationregistry表中，并且用户也未收到此通知。

  

输出：-{mvccVersion = 0，uuid = 4735d3f5-3403-d354-b575-ceed6e50b5cc，   userNotificationEventId = 1985806，companyId = 20155，userId = 58202，   type = travelportalertportlet_WAR_travelportalertportlet，   timestamp = 1562321525263，deliveryType = 0，deliverBy = 0，delivered = true，   有效载荷= {“ classPK”：“ 6001”，“ createdDate”：“”格林尼治标准时间07年4月4日14:17:34   2019“，” modifiedDate“：” Fri Jul 05 10:03:02 GMT   2019“，” entryDescription“：”警报为   working“，” entryURL“：” http://localhost:8080/group/agency/service-alerts?p_p_id=travelportalertportlet_WAR_travelportalertportlet&p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&_travelportalertportlet_WAR_travelportalertportlet_id=6001&_travelportalertportlet_WAR_travelportalertportlet_render=alert-view“，” className“：” com.travelport.alert.model.Alert“，” tagText“：” _ AND_0“，” notificationType“：1，” entryTitle“：”警报   正在工作”，“ emailSubject”：“服务警报已更新-警报为   working'“，” userId“：” 58202“，” status“：” ONGOING“}，actionRequired = false，   archived = false}
