java.lang.NoClassDefFoundError：org / hibernate / cache / EntityRegion配置EHCache

我正在尝试将ehcache （v2.6.0）添加到我的Hibernate 4.1.5.SP1项目中，但有一些配置问题。 具体来说，当我尝试构建我的Hibernate配置时，我收到了java.lang.NoClassDefFoundError ： org/hibernate/cache/EntityRegion错误

  true net.sf.ehcache.hibernate.EhCacheRegionFactory 

这是我的Maven依赖…

  4.1.5.SP1 4.3.0.Final 2.6.0 ...   org.hibernate hibernate-validator ${hibernate.validator.version}   org.hibernate hibernate-entitymanager ${hibernate.version}   net.sf.ehcache ehcache-core ${ehcacheVersion}  

这是我用来配置它的Java代码……

  Configuration config = new Configuration() .setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect") .setProperty("hibernate.connection.driver_class", "org.hsqldb.jdbcDriver") .setProperty("hibernate.connection.url", "jdbc:hsqldb:mem:myprojectTestDb") .setProperty("hibernate.connection.username", "sa") .setProperty("hibernate.connection.password", "") .setProperty("hibernate.connection.pool_size", "1") .setProperty("hibernate.connection.autocommit", "true") .setProperty("hibernate.cache.provider_class", "org.hibernate.cache.HashtableCacheProvider") .setProperty("hibernate.hbm2ddl.auto", "create-drop") .setProperty("hibernate.show_sql", "true") .setProperty("hibernate.current_session_context_class", "thread") .setProperty("hibernate.cache.use_second_level_cache", "true") .setProperty("hibernate.cache.region.factory_class", "net.sf.ehcache.hibernate.EhCacheRegionFactory") .addAnnotatedClass(Organization.class) .addAnnotatedClass(State.class) .addAnnotatedClass(Country.class) .addAnnotatedClass(Domain.class) .addAnnotatedClass(Community.class); final ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry(); sessionFactory = config.buildSessionFactory(serviceRegistry); 

这是可怕的错误。 我错过了什么配置？

Answer 1

ehcache-core文件基本上适用于Hibernate 3.x. Hibernate 4.x附带了自己的ehcache实现。 您不需要在hibernate 4.x中显式使用ehcache。 这是您问题的最佳答案。

Answer 2

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

对于Hibernate 4，请使用

 org.hibernate.cache.ehcache.EhCacheRegionFactory instead of net.sf.ehcache.hibernate.EhCacheRegionFactory

Answer 3

我检查了maven的依赖项。 当加载hibernate-ehcache包时，Maven总是加载ehcache-code。

依赖树：

 +--- org.hibernate:hibernate-ehcache:4.3.0.Final | +--- org.jboss.logging:jboss-logging:3.1.3.GA | +--- org.jboss.logging:jboss-logging-annotations:1.2.0.Beta1 | +--- org.hibernate:hibernate-core:4.3.0.Final (*) | \--- net.sf.ehcache:ehcache-core:2.4.3 | \--- org.slf4j:slf4j-api:1.6.1 -> 1.6.6 

请检查您的持久性配置。 它不应该包含包名称以“net.sf”开头的任何类

例如，您必须在代码中替换以下字符串：

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

使用以下字符串：

 .setProperty("hibernate.cache.region.factory_class", "org.hibernate.cache.ehcache.EhCacheRegionFactory") 

Answer 4

从Hibernate 4开始，新的hibernate-cache引入了缓存。 这需要net.sf.ehcache最新依赖为2.6。 以下文章将点击链接 。 当我在我的pom中添加以下依赖项时，错误将删除：

   net.sf.ehcache ehcache 2.8.3
