Spring4集成Hibernate5

Spring4集成Hibernate5

Hibernate5相比hibernate4做了一些调整会涉及到配置文件的变更

Hibernate官方给出的文档中描述了这些变更

The transaction SPI underwent a major redesign as part of 5.0 as well. From a user perspective this generally only comes into view in terms of configuration. Previously applications would work with the different backend transaction stratagies directly via the org.hibernate.Transaction API. In 5.0 a level of indirection has been added here. The API implementation of org.hibernate.Transaction is always the same now. On the backend, the org.hibernate.Transactionimpl talks to a org.hibernate.resource.transaction.TransactionCoordinator which represents the "transactional context" for a given Session according to the backend transaction strategy. Users generally do not need to care about the distinction.

The change is noted here because it might affect your bootstrap configuration. Whereas previously applications would specify hibernate.transaction.factory_class and refer to a org.hibernate.engine.transaction.spi.TransactionFactoryFQN, with 5.0 the new contract is org.hibernate.resource.transaction.TransactionCoordinatorBuilder and is specified using the hibernate.transaction.coordinator_class setting. Seeorg.hibernate.cfg.AvailableSettings.TRANSACTION_COORDINATOR_STRATEGY JavaDocs for additional details.

The following short-names are recognized: jdbc::(the default) says to use JDBC-based transactions (org.hibernate.resource.transaction.backend.jdbc.internal.JdbcResourceLocalTransactionCoordinatorImpl) jta::says to use JTA-based transactions (org.hibernate.resource.transaction.backend.jta.internal.JtaTransactionCoordinatorImpl)

See the User Guide for additional details.

hibernate4中事务管理配置方式

hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

hibernate5中使用以下方式

hibernate.transaction.coordinator_class=jdbc

 

配置的值使用短名称，不再使用完整的类名，jdbc代表org.hibernate.resource.transaction.backend.jdbc.internal.JdbcResourceLocalTransactionCoordinatorImpl，

jta代表org.hibernate.resource.transaction.backend.jta.internal.JtaTransactionCoordinatorImpl
