JPA二级缓存在wildfly8.2中，hibernate-entitymanager 4.3.8.Final [英] JPA second level cache in wildfly8.2, hibernate-entitymanager 4.3.8.Final

问题描述

我试图在wildfly8.2中使用二级缓存
我通过JavaConfig设置属性
Properties properties = new Properties（）;
properties.setProperty（hibernate.hbm2ddl.auto，hibernateHbm2ddlAuto）;
properties.setProperty（hibernate.dialect，hibernateDialect）;
properties.setProperty（hibernate.show_sql，true）;
properties.setProperty（hibernate.cache.use_second_level_cache，true）;
properties.setProperty（hibernate.cache.use_query_cache，true）;

但我得到以下错误：

• 引起：org.hibernate.cache.NoCacheRegionFactoryAvailableException：在应用程序中使用二级缓存，但未给出属性hibernate.cache.region.factory_class;请使用hibernate.cache.region.factory_class设置禁用二级缓存或设置正确的区域工厂，并确保二级缓存提供程序（例如hibernate-infinispan）在类路径中可用。

为什么按照文档给出错误并不是必需的。任何输入都会有帮助。

JPA在WildFly共享缓存/二级缓存

  Configuration.setProperty（hibernate.cache.region.factory_class，net.sf.ehcache.hibernate.EhCacheRegionFactory）
  

我会使用C3P0或Infinispam作为二级缓存。

I am trying to use second level cache in wildfly8.2 I am setting the properties via JavaConfig Properties properties = new Properties(); properties.setProperty("hibernate.hbm2ddl.auto", hibernateHbm2ddlAuto); properties.setProperty("hibernate.dialect", hibernateDialect); properties.setProperty("hibernate.show_sql", "true"); properties.setProperty("hibernate.cache.use_second_level_cache", "true"); properties.setProperty("hibernate.cache.use_query_cache" , "true");

but I get the following error

• 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.

Why is it giving that error as per documentation it is not required. Any input would be helpful.

JPA shared cache / second level cache in WildFly

Thanks Sanjeev.

解决方案

You need to define the property hibernate.cache.region.factory_class, something like:

Configuration.setProperty("hibernate.cache.region.factory_class", "net.sf.ehcache.hibernate.EhCacheRegionFactory")

I would use C3P0 or Infinispam as second level cache.
