我正在尝试在 TOMCAT 中部署一个应用程序，但遇到了这个不寻常的错误(我的意思是以前从未遇到过)。
27-Jul-2015 12:41:49.870 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.listenerStart Error configuring application listener of class websocket.drawboard.DrawboardContextListener
java.lang.ClassNotFoundException: websocket.drawboard.DrawboardContextListener
27-Jul-2015 12:41:49.870 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.listenerStart Skipped installing application listeners due to previous error(s)
27-Jul-2015 12:45:35.141 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.listenerStart Error configuring application listener of class listeners.ContextListener
java.lang.ClassNotFoundException: listeners.ContextListener
27-Jul-2015 12:45:35.146 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.listenerStart Error configuring application listener of class listeners.SessionListener
java.lang.ClassNotFoundException: listeners.SessionListener
该应用程序是基于 spring 的。 web.xml 如下所示:
<!--Application Context-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--Dispatcher Servlet-->
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
pom.xml 文件如下所示:

我想知道这里有什么问题。我之前已经在 TOMCAT 中部署了应用程序，但没有收到任何错误消息。我已经看过其他帖子和论坛，但无法解决。
提前致谢!
最佳答案
我不知道是什么问题，但在我下载了 Tomcat VERSION 8.0.24 之后，我再也没有遇到过这个问题。与 VERSION 8.0.21 一样的问题
关于java - Tomcat错误信息 : java. lang.ClassNotFoundException : listeners. ContextListener/SessionListener/websocket.drawboard.DrawboardContextListener，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31659129/
