web.xml配置文件中<async-supported>true</async-supported>报错的解决方案

web.xml总是报cvc-complex-type.2.4.a: Invalid content was found starting with element 错误

在eclipse中的web.xml添加： 1、 http://www.springmodules.org/schema/cache/springmodules-cache.xsd 2、http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd 如下面代码：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
