简单ehcache项目异常

Question

我目前正在将一些项目转换为maven，并且在战争开始时遇到了一些问题。因此，我刚刚创建了一个非常简单的ehcache maven项目，我得到了一个类加载器类型的问题。这是我的POM：

<ehcache:annotation-driven />

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
    <property name="cacheManager" ref="ehcache" />
</bean>

<bean id="ehcache"
    class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
    <property name="configLocation" value="/WEB-INF/ehcache.xml" />
</bean>

<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-INF/pages/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

我在springmvc部分中还没有使用ehcache就已经有了HelloWorld类型的mvc设置。

我错过了什么？我假设它很简单，但我的项目看起来就像一个简单的ehcache项目的几乎所有hello world类型的配置。

Spring的EHCacheCheManager类充当EhCacheCacheManager实例的包装器。EHCacheManagerFactoryBean生成已经包装在EHCacheCheManager对象中的bean。所以基本上你是在尝试包装一个已经包装好的对象。相反，只需创建一个bean（使用工厂），您就会得到您想要的：

<bean id="cacheManager" 
    class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
  <property name="configLocation" value="/WEB-INF/ehcache.xml" />
</bean>

如果需要引用EhCacheCacheManager实例，则可以在此CacheManagerbean的getCacheManager()字段中获得该实例。
