解决方法:

将“http://www.springmodules.org/schema/cache/springmodules-cache.xsd http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd”这段话加入到xml文件的"xmlns:xsi="的标签中

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance http://www.springmodules.org/schema/cache/springmodulescache.xsd 
               http://www.springmodules.org/schema/cache/springmodulesehcache.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
