使用Idea构建springmvc框架，出现no bean named ‘cacheManager’ is defined 错误。

不可否认IDEA确实是最好的java开发软件，各种提示智能的有点非人类，集成的git也很强大，git命令几乎都不需要敲啦，界面也比较美观。。。：

但也是由于提示太多啦也导致一堆的问题：
下面是我构建springmvc的步骤：其中就是由于一个不注意，产生一大波错误困扰我好久好久……

首先创建一个maven项目，在pom文件中添加依赖的jar包

这个是所以的依赖，我这主要是出错啦为防止意外所以
以相关的包都导入啦。

配置springmvc-servlet.xml文件，配置好包扫描，mvc注解，及视图解释配置

由于IDEA的自动补全功能非常强大，当你配置 <mvc:annotation-driven/>后编译器会帮你自动补全上面两个配置文件约束。这个时候如果你没注意的就会爆出一个很莫名奇妙的错：
- 上面主要爆这个错：九月 25, 2017 823 上午 org.apache.catalina.core.ApplicationContext log
信息: Initializing Spring FrameworkServlet ‘springmvc’
九月 25, 2017 823 上午 org.apache.catalina.core.ApplicationContext log
严重: StandardWrapper.Throwable
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.cache.interceptor.CacheInterceptor#0’: Cannot resolve reference to bean ‘cacheManager’ while setting bean property ‘cacheManager’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named ‘cacheManager’ is defined
at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:329).getSingleton(DefaultSingletonBeanRegistry.java:223)
at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:292)。

报错原因是：Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named ‘cacheManager’ is defined

这里主要是因为上面springmvc-servlet.xml配置文件中由于IDEA自动配置啦cache,但配置文件中又没有指定缓存的空间，JVM虚拟机中也有个cacheManage,这就导致spring进行bean管理时扫描到两个cache Manage 导致都不能正常加载，爆错，而你在配置时明明没有使用到缓存，却老是报一个缓存的错误，实在很懵逼。
