我正在尝试将 ehcache（v2.6.0）添加到我的 Hibernate 4.1.5.SP1 项目中，但一些配置问题。具体来说，当我尝试使用时，会出现 java.lang.NoClassDefFoundError: org/hibernate/cache/EntityRegion 错误构建我的 Hibernate 配置。
<property name="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</property>
以下是我的Maven依赖...
<hibernate.version>4.1.5.SP1</hibernate.version>
<hibernate.validator.version>4.3.0.Final</hibernate.validator.version>
<ehcacheVersion>2.6.0</ehcacheVersion>
...
<!-- Hibernate dependencies -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>${hibernate.validator.version}</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>${hibernate.version}</version>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache-core</artifactId>
<version>${ehcacheVersion}</version>
</dependency>
这是我用来配置的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);
这里出现了一个令人不爽的错误。我缺少哪些配置？
