[spring-mvc] 启动时报 No bean named 'cacheManager' available

简介

今天在配制一个mvc web项目时，居然出现了如下异常，百思不得其解

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'cacheManager' available

解决办法

原因 xml mvc的命名空间 配制错误了，错误的配制如下：

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

    <mvc:annotation-driven/>
</beans>    

把其改为如下配制，就不会报异常了
xmlns:mvc=”http://www.springframework.org/schema/mvc”
xsi:schemaLocation=”http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd”

<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
