【Spring】The matching wildcard is strict……

applicationContext.xml 文件抛出了这个异常信息。
解决方法：
需要在 namespace 后加上对应的 schemaLocation，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
	   http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd ">

PS: Spring 的 schemaLocation 参考 http://www.springframework.org/schema/
