java - Ehcache:找不到缓存

Question

我在我的应用程序中使用Ehcache+Spring+Hibernte，这里有一些详细信息 低于异常

Caused by: com.googlecode.ehcache.annotations.CacheNotFoundException: Unable to find cache 'com.ccc.spring.model.Validuserrole' at com.googlecode.ehcache.annotations.impl.CacheAttributeSourceImpl.getCache(CacheAttributeSourceImpl.java:223) at com.googlecode.ehcache.annotations.impl.CacheAttributeSourceImpl.parseCacheableAnnotation(CacheAttributeSourceImpl.java:325) at com.googlecode.ehcache.annotations.impl.CacheAttributeSourceImpl.findMethodAttribute(CacheAttributeSourceImpl.java:268) at com.googlecode.ehcache.annotations.impl.CacheAttributeSourceImpl.computeMethodAttribute(CacheAttributeSourceImpl.java:242) at com.googlecode.ehcache.annotations.impl.CacheAttributeSourceImpl.getMethodAttribute(CacheAttributeSourceImpl.java:167) at com.googlecode.ehcache.annotations.impl.CacheAttributeSourceImpl.getAdviceType(CacheAttributeSourceImpl.java:122) at com.googlecode.ehcache.annotations.impl.CacheStaticMethodMatcherPointcut.matches(CacheStaticMethodMatcherPointcut.java:46) at org.springframework.aop.support.AopUtils.canApply(AopUtils.java:225) at org.springframework.aop.support.AopUtils.canApply(AopUtils.java:262) at org.springframework.aop.support.AopUtils.findAdvisorsThatCanApply(AopUtils.java:294) at org.springframework.aop.framework.autoproxy.AbstractAdvisorAutoProxyCreator.findAdvisorsThatCanApply(AbstractAdvisorAutoProxyCreator.java:118) at org.springframework.aop.framework.autoproxy.AbstractAdvisorAutoProxyCreator.findEligibleAdvisors(AbstractAdvisorAutoProxyCreator.java:88) at org.springframework.aop.framework.autoproxy.AbstractAdvisorAutoProxyCreator.getAdvicesAndAdvisorsForBean(AbstractAdvisorAutoProxyCreator.java:69) at org.springframework.aop.framework.autoproxy.AbstractAutoProxyCreator.wrapIfNecessary(AbstractAutoProxyCreator.java:376) at org.springframework.aop.framework.autoproxy.AbstractAutoProxyCreator.postProcessAfterInitialization(AbstractAutoProxyCreator.java:339) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsAfterInitialization(AbstractAutowireCapableBeanFactory.java:421) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1558) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:539) ... 21 more

这是我的 ehcache.xml 文件

<ehcache>

    <defaultCache maxElementsInMemory="100" eternal="false"
        timeToIdleSeconds="120" timeToLiveSeconds="200" />
    <cache name="com.ccc.spring.model.Validuserrole" maxElementsInMemory="100"
        eternal="false" timeToIdleSeconds="5" timeToLiveSeconds="2000" />

</ehcache>

applicationContext.xml 文件条目

<ehcache:annotation-driven />

    <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="/WEB-INF/ehcache.xml" />

    </bean>

    <context:component-scan base-package="com.ccc.spring" />

在 DAO 中我使用下面的代码

@Cacheable(cacheName="com.ccc.spring.model.Validuserrole")
    public List<Validuserrole> getRoleList() {
        List list = getSessionFactory().getCurrentSession()
                .createQuery("from Validuserrole where active = ?")
                .setParameter(0, true).list();
        return list;
    }

但仍然找不到缓存。

编辑

@Cacheable( value = { "com.ccc.spring.model.Validuserrole" })
    public List<Validuserrole> getRoleList() {
        List list = null;
        try{
          list = getSessionFactory().getCurrentSession()
                .createQuery("from Validuserrole ").list();
        }
        catch(Exception e){
            e.printStackTrace();
        }
        return list;
    }

另一次编辑

问题是您在 Spring + EhCache 集成中使用了错误的注释。您需要使用 org.springframework.cache.annotation.Cacheable 而不是 com.googlecode.ehcache.annotations.Cacheable。

查看this和 this有关如何使用 Spring 的缓存支持(随 Spring 3.1 引入)和 EhCache 作为缓存提供程序的更多信息
