No WebApplicationContext found: no ContextLoaderLi

记录一下自己解决tomcat部署遇得到问题的全过程
首先，在tomcat部署上面部署项目时，报如下错误：
严重: Error listenerStart
2014-7-24 14:25:44 org.apache.catalina.core.StandardContext start
严重: Context [/filemanager] startup failed due to previous errors
查了查说是版本问题，将WEB-INF下的web.xml中的

<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener </listener-class>
    </listener>

改为：

<listener>
        <listener-class>org.springframework.web.context.ContextLoaderServlet</listener-class>
 </listener>

就可以了，结果部署过程中，系统报如下错误：
2014-7-24 14:15:24 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet fileUpload threw exception
java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?

at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489)
at java.lang.Thread.run(Thread.java:619)

找了好多办法，最后只有将：

<listener-class>org.springframework.web.context.ContextLoaderServlet</listener-class>

换成：

<servlet>
<servlet-name>SpringContextServlet </servlet-name>
<servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
<load-on-startup>1 </load-on-startup>

结果，在部署项目是报了如下错误：
严重: StandardWrapper.Throwable
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sessionFactory‘ defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/collections/map/LRUMap

在百度上查了好长时间，最后确定是：在commons-collections-2.1.1.jar包中找到了LRUMap.class文件但他没在map文件夹下而是直接放在了collections下。后来换了个包commons-collections-3.1.jar.问题解决。
然后呢，我有突发奇想将WEB-INF/web.xml中的

<servlet-name>SpringContextServlet </servlet-name>
<servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
<load-on-startup>1 </load-on-startup>

改回了

<listener-class>org.springframework.web.context.ContextLoaderListene</listener-class>

结果还是一切正常，万事大吉。
