我正在尝试使用EhCache使用Sping Annotation缓存。所以，首先，我将依赖项添加到我的pom.xml中，并将application-context.xml配置为：
<ehcache:annotation-driven cache-manager="cacheManager" />
<ehcache:config cache-manager="cacheManager">
<ehcache:evict-expired-elements interval="60" />
</ehcache:config>
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation" value="ehcache.xml"/>
</bean>
这是ehcache.xml配置文件：
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
<defaultCache eternal="true" maxElementsInMemory="100" overflowToDisk="false" />
<cache name="alfresco" maxElementsInMemory="10" eternal="true" overflowToDisk="false" />
</ehcache>
最后，我将Annontation @Cachable添加到需要缓存的方法中：
@Cacheable(value="alfresco")
public EMContents getContents(RestTemplate restTemplate, String ticket, String webScriptUrl, String em_name)
我创建一个junit类来调用两次相同的方法，并且第二次不使用缓存（第一次不创建键值）。
似乎工作正常，但我收到了这条消息：

有任何线索吗？我的配置似乎有些问题。
感谢您的时间和安德里亚

安德烈，
确保带有@Cachable注释的bean实例是Spring管理的实例，而不是您自己创建的实例。如果您有正确的日志，则在调用该方法时，日志将生成类似的内容：
2012-11-16 09:40:21,731 [http-8081-2] DEBUG com.googlecode.ehcache.annotations.interceptor.EhCacheInterceptor - Generated key '1396312488991822982' for invocation: ReflectiveMethodInvocation: public edu.wmich.gowmu.sso.dataobject.User edu.wmich.gowmu.sso.bl.UserManager.getUser(java.lang.String,java.lang.String); target is of class [edu.wmich.gowmu.sso.bl.UserManager]
