CRM项目报错笔记——web.xml中<async-supported>报错

错误一：

cvc-complex-type.2.4.a: Invalid content was found starting with element 'async-supported'. One of

 '{"http://java.sun.com/xml/ns/javaee":init-param}' is expected.


<async-supported>true</async-supported>
解决方案：

xmlns中再加两行

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

如：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://java.sun.com/xml/ns/javaee
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/javaee 
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
