未配置带有CacheDecoratorFactory的Spring的Ehcache

Question

我正在用Spring项目实现ehcache，但没有成功。

下面是我在applicationContext.xml中的设置：

<ehcache:annotation-driven />
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
    <property name="configLocation" value="/META-INF/spring/ehcache.xml" />
</bean>

下面是我在ehcache.xml中的设置：

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">    

    <diskStore path="java.io.tmpdir" /> 
    <defaultCache eternal="true" maxElementsInMemory="100" overflowToDisk="false" />
    <cache name="listTop" maxElementsInMemory="10" eternal="true" overflowToDisk="false" />

</ehcache>

下面是我的实现类：

@Cacheable(cacheName="listTop")
public void listTop(News news, String regionCode, Integer count, Integer categoryId, String listType){
//code here//
}

我收到以下消息，似乎缓存未配置：

有没有人知道并提供帮助？非常感谢。

Answer 1

您需要告诉EhCache将装饰器应用于已定义的缓存，如下所示(并且您必须实现MyCacheDecoratorFactory来执行您想要的操作)：

<cache name="listTop" maxElementsInMemory="10" eternal="true" overflowToDisk="false" ><cacheDecoratorFactory class="com.test.MyCacheDecoratorFactory", properties="blah=true,someValue=2000" /></cache>

Answer 2

缓存不工作与CacheDecoratorFactory无关。这些是调试日志，告诉您没有使用CacheDecoratorFactory。

CacheDecorator是开发人员向缓存添加功能的一种方式。更多关于Ehcache 2.8 documentation的信息。

请注意，3.0中的CacheDecoratorFactory类消失了
