假设您将 JPA 与 Spring 一起使用,并将 Hibernate 作为 JPA 实现。JPA事务模式为“JTA”,所以需要将容器transactionManager传递给Hibernate。经典答案是hibernate.transaction.manager_lookup_class
为您的服务器设置匹配类。
但是,我认为这取决于服务器特定的配置是一种耻辱,因为您已经在 Spring 中找到了带有<tx:jta-transaction-manager>
.
有没有办法通过类似的配置将此 transactionManager 提供给 Hibernate
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="persistence_unit_name"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.transaction.manager_lookup_class">
org.hibernate.transaction.SunONETransactionManagerLookup
</prop>
</props>
</property>
</bean>
<tx:jta-transaction-manager/>
目标是摆脱org.hibernate.transaction.SunONETransactionManagerLookup
财产。顺便说一句,我确实想到了两种不同的服务器实现。
编辑:如果没有事务管理器配置,Hibernate 在创建 EntityManagerFactory 时会阻塞:
