关于 class path resource [applicationContext.xml] cannot be opened because it does not exist 的异常处理

写这篇文章  谨记让我找了4个小时的bug!!!!!

Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [applicationContext.xml]; nested exception is Java.io.FileNotFoundException: class path resource [applicationContext.xml] cannot be opened because it does not exist

web配置文件

 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:applicationContext.xml</param-value>
 </context-param>

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

发现是由于classpath不是指向resource路径，导致一直找不到文件。需要在classpath后面加个*，这样就解决问题了。
