在配置注解处理器映射器、处理器适配器时，已引入 xmlns:mvc="http://www.springframework.org/schema/mvc"和
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
后，在写<mvc:annotation-driven/>时，报The matching wildcard is strict, but no declaration can be found for element 'mvc:annotation-driven'.错误可以在xsi:schemaLocation中添加tx支持，即添加如下代码：
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd" >
问题就解决啦！
