1.在原来xmlns下面添加一行
xmlns:context="http://www.springframework.org/schema/context"
2.在原来xsi:schemaLocation中添加不同的内容(也可以直接复制粘贴全部替代全部xsi的内容)
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"
