我们在GlassFish中运行了一个用Java编写的Web应用程序，该应用程序将EhCache用作第二级缓存机制。我们确定流量不保证二级缓存，并已选择将其删除。但是，显然这比最初的想象要简单。

我将persistence.xml更改为包括... <property name="hibernate.cache.use_second_level_cache" value="false"/>，并从我们的Maven POM中删除了ehcache。

通过... EntityManagerFactory emf = Persistence.createEntityManagerFactory("devDB");对其进行读取和初始化。

完整的persistence.xml ...

当我将应用程序部署到Glassfish时，它抱怨... Caused by: org.hibernate.cache.NoCacheRegionFactoryAvailableException: Second-level cache is used in the application,but property hibernate.cache.region.factory_class is not given; please either disable second level cache or set correct region factory using the hibernate.cache.region.factory_class setting and make sure the second level cache provider (hibernate-infinispan,e.g.) is available on the classpath.

还有其他可以设置的地方吗？
