我想在nuxeo IDE中安排一个事件,但是我收到错误java.lang.ClassCastException:

  

org.nuxeo.ecm.core.event.impl.EventContextImpl无法强制转换为   org.nuxeo.ecm.core.event.impl.DocumentEventContext。

我的日程安排贡献是:

<?xml version="1.0"?>

<component name="org.nuxeo.sample.ScheduleCall" version="1.0">
<extension target="org.nuxeo.ecm.core.scheduler.SchedulerService"
 point="schedule">
 <schedule id="testschedule">
 <username>Administrator</username>
 <eventId>user_created</eventId>
 <eventCategory>default</eventCategory>

 <cronExpression>0 1 * * * ?</cronExpression>
 </schedule>
 </extension>  

</component>

我的听众贡献是:

<component name="org.nuxeo.sample.listener.contrib.ScheduleListener">

  <extension target="org.nuxeo.ecm.core.event.EventServiceComponent"
    point="listener">

    <listener name="schedulelistener" async="false" postCommit="true"
      class="org.nuxeo.sample.ScheduleListener" priority="140">
      <event>user_created</event>
    </listener>
  </extension>

</component>

我的侦听器java类是:

/**
 * 
 */

package org.nuxeo.sample;

import org.nuxeo.ecm.core.event.EventListener;
import org.nuxeo.ecm.core.event.Event;





/**
 * @author Parul.Puri01
 */


public class ScheduleListener implements EventListener {

    public void handleEvent(Event event){
        try{
            if(event!=null && event.getName().equals("user_created")){
                System.out.println("parul");
            }
            System.out.println("not an event");
       }
        catch (Exception e){
            e.printStackTrace();

        }


    }

}

错误是:

请告诉我如何在nuxeo IDE中创建侦听器扩展点。我正在创建它作为文档监听器。如何解决错误?

答案 0 :(得分:2)

user_created eventId由Nuxeo平台在文档上下文中内部使用。

因此,您无法使用没有文档上下文的调度程序触发此同一事件。

如果您想让您的示例正常工作,只需将 user_created 重命名为 my_user_created 或其他任何内容。

最佳,
