org.hibernate.cache.CacheException：不支持的访问类型[读写]

我正在尝试使用EhCache启用二级缓存，但在我的服务器启动时遇到问题 . 当我为我的DTO类指定@Cache（usage = CacheConcurrencyStrategy.READ_WRITE）时，我收到以下错误：

16：20：42,882 ERROR [org.jboss.as.controller.management-operation]（控制器启动线程）JBAS014612：操作（“部署”）失败 - 地址：（[（“deploy ment”=>“PORTAL.ear “）] - 失败描述：{”JBAS014671：Failed services“=> {”jboss.persistenceunit . \“PORTAL.ear＃AppPU \”“=>”org.jb oss.msc.service.StartException in service jboss . persistenceunit . \“PORTAL.ear #AppPU \”：javax.persistence.PersistenceException：[PersistenceUnit：AppPU]无法构建EntityManagerFactory引起：javax.persistence.PersistenceException：[PersistenceUnit：AppPU]无法构建EntityManagerFactory引起：org . hibernate.cache.CacheException：不支持的访问类型[读写]“}}

如果我使用CacheConcurrencyStrategy.READ_ONLY，我没有遇到任何启动问题 .

Below is my persistence.xml:

<persistence-unit name="AppPU" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:jboss/myDS</jta-data-source>
      <exclude-unlisted-classes>false</exclude-unlisted-classes>
      <shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>
      <properties>
          <!-- Auto-detect entity classes -->
          <property name="hibernate.archive.autodetection" value="class, hbm"/>

          <!-- Print sql executed - useful for debugging -->
          <property name="hibernate.show_sql" value="false"/>
          <property name="hibernate.format_sql" value="false"/>

         <!-- Properties for Hibernate -->
         <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
          <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
          <property name="hibernate.cache.provider_class" value="net.sf.Ehcache.hibernate.SingletonEhcacheProvider"/>
         <!--  <property name="hibernate.cache.region.factory_class" value="net.sf.ehcache.hibernate.EhCacheRegionFactory"/> -->
        <property name="net.sf.Ehcache.configurationResourceName" value="/ehcache.xml"/>
        <property name="hibernate.cache.use_query_cache" value="true"/>
        <property name="hibernate.cache.use_second_level_cache" value="true"/>
        <property name="hibernate.generate_statistics" value="true"/>
       </properties>
   </persistence-unit>

我想使用READ_WRITE来启用二级缓存 .

有人可以帮我解决这个问题吗？提前致谢 .
