SSM框架遇到异常Error creating bean with name 'org.springframework.cache.interceptor.CacheInterceptor#0'

昨天搭ssm框架时，遇到上面的异常，一脸懵比，我没用过这个bean啊，后来度娘找到了解决方法，是mvc的配置文件

<mvc:annotation-driven/>

，idea自动导入命名空间时出现了问题，导成了↓(含 cache) 这种，删除掉重新导入就行了。

1. ​​<beans xmln="http://www.springframework.org/schema/beans"​​
2. ​​xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"​​
3. ​​xmlns:context="http://www.springframework.org/schema/context"​​
4. ​​<span style="color:#ff0000;"> xmlns:mvc="http://www.springframework.org/schema/cache"</span>​​
5. ​​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 <span style="color:#ff0000;">http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd</span>">​​

正确的命名空间是↓ 这种：

<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:mvc="http://www.springframework.org/schema/mvc"
       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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
