嗨,我遇到了一些hibernate二级缓存的问题.作为缓存提供程序,我使用ehcache.
来自persistence.xml的配置的一部分
<property name="hibernate.cache.use_second_level_cache" value="true"/>
<property name="hibernate.cache.provider_class" value="net.sf.ehcache.hibernate.EhCacheProvider" />
<property name="hibernate.cache.provider_configuration_file_resource_path" value="/ehcache.xml" />
我使用注释配置我的实体,所以:
@Cache(region = "Kierunek", usage = CacheConcurrencyStrategy.READ_WRITE)
public class Kierunek implements Serializable {
这些注释的导入是:
import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;
我的ehcache.xml
<diskStore path="java.io.tmpdir" />
<defaultCache maxElementsInMemory="10000" eternal="false"
timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true"
diskSpoolBufferSizeMB="30" maxElementsOnDisk="10000000"
diskPersistent="false" diskExpiryThreadIntervalSeconds="120"
memoryStoreEvictionPolicy="LRU" />
<cache name="Kierunek" maxElementsInMemory="1000"
eternal="true" overflowToDisk="false" memoryStoreEvictionPolicy="LRU" />
谁知道为什么我会得到以下错误？
WARNING: Could not find a specific ehcache configuration for cache named [persistence.unit:unitName=pz2EAR.ear/pz2EJB.jar#pz2EJB.Kierunek]; using defaults.
