Java 找不到HibernateListener类错误

我正在尝试创建hibernate侦听器。我是在本文的帮助下创建的侦听器。 在web.xml中，我配置了侦听器。我遇到以下错误。如何解决此问题

    SEVERE: Exception sending context initialized event to listener instance of class

我将共享web.xml

您是否将dom4j添加为maven依赖项？你用maven吗？如果不只是下载dom4j并将jar放在类路径中，我没有使用maven依赖项。我还将jar添加到类路径中。这一行仍然显示issueError正在发生，config=new Configuration（）.configure（url）；问题是您的jar对于tomcat仍然不可用。Hibernate在configure方法中使用XMLHelper类，XMLHelper使用Jdom将这个dom4j jar放在tomcat lib目录中
