SSM报错“No bean named 'cacheManager' is defined”

错误

No bean named 'cacheManager' is defined。

错误代码

<?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:mvc="http://www.springframework.org/schema/cache"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd

       http://www.springframework.org/schema/cache
       http://www.springframework.org/schema/cache/spring-cache.xsd">

    <!-- 使用扫描机制，扫描包 -->
    <context:component-scan base-package="controller"/>
    <context:component-scan base-package="service"/>
    <context:component-scan base-package="dao"/>
    <context:component-scan base-package="pojo"/>

    <mvc:annotation-driven/>

    <!-- 配置视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          id="internalResourceViewResolver">
        <!-- 前缀 -->
        <property name="prefix" value="/html/"/>
        <!-- 后缀 -->
        <property name="suffix" value=".html"/>
    </bean>
</beans>

原因

IDEA会自动补全为cache。

解决

将cache改为mvc。
