web.xml <async-supported>标签报错解决方法

 在MyEclipse中配置web.xml加上：
  1、 http://www.springmodules.org/schema/cache/springmodules-cache.xsd

   2、http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd 

如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance http://www.springmodules.org/schema/cache/springmodules-cache.xsd http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd "
xmlns="http://java.sun.com/xml/ns/javaee"
