web.xml 节点错误提示 cvc-complex-type.2.4.a: Invalid content was found starting with element

     在写xml的时候总是报cvc-complex-type.2.4.a: Invalid content was found starting with element 错误，还出现小红叉，在网上找了很多，有说是把报红叉的代码写在<jsp-config></jsp-config>之间，试了之后发现完全没用。 

   后来找到了一个方法就把问题解决了

 解决办法为：

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 id="WebApp_ID" version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.springmodules.org/schema/cache/springmodules-cache.xsd http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
