web.xml报错: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.
在写xml的时候又一次总是报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。
后来在外文网站上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
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
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"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd ">
