------解决方法--------------------------------------------------------
错误说明很清楚呀
------解决方法--------------------------------------------------------
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

//检查spring相关的jar在不在tomcat的发布工程的lib下
------解决方法--------------------------------------------------------
xml设置里面用到的bean不对，可能名字写错了。
------解决方法--------------------------------------------------------
web.xml 文件的
<listener>
标签必须在
<servlet>
之前

<listener>
<listener-class>
  org.springframework.web.context.ContextLoaderListener
  </listener-class>
</listener>
<servlet>
<description>
</description>
<display-name>
TimeServlet </display-name>
<servlet-name>TimeServlet </servlet-name>
<servlet-class>
TimeServlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TimeServlet </servlet-name>
<url-pattern>/TimeServlet </url-pattern>
</servlet-mapping>

要是位置颠倒的话，就会报错！
