方法一: 
第一:發現原來是他的配置文件不是放在WEB-INF下，而是放在src目錄下，解決的方法可將其spring的配置文件applicationContext轉移陣地，轉到WEB-INF下，或在web.xml下加入如下語句： 
<!-- Spring ApplicationContext配置文件的路徑,可使用通配符，多個路徑用,號分隔此參數用於後面的Spring-Context loader --> 

<context-param> 

<param-name>contextConfigLocation</param-name> 

<param-value>/WEB-INF/applicationContext*.xml,classpath*:applicationContext*.xml</param-value> 

</context-param> 

第二:在web.xml裏面加上樓上說的 
<listener> 
<listener-class> 
org.springframework.web.context.ContextLoaderListener 
</listener-class> 
</listener>
