我刚刚从 Hibernate 4.2.19 更新到 Hibernate 5.1.2。当然，这并不是说事情没有按计划进行。在解决了几个问题（其中 JOIN FETCH 必须替换为 JOIN）之后，我现在遇到了下一个问题：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'idolConfig': Invocation of init method failed; nested exception is org.hibernate.resource.transaction.backend.jta.internal.JtaPlatformInaccessibleException: Unable to access TransactionManager or UserTransaction to make physical transaction delegate

我没有persistence.xml文件。这是我的spring.xml:

<tx:jta-transaction-manager />
<tx:annotation-driven/>
EDIT:
将以下内容添加到 bean 属性并没有解决我的问题（我还降级到 Hibernate 5.0.0，但问题仍然存在）：
<prop key="hibernate.transaction.coordinator_class">org.hibernate.resource.transaction.backend.jta.internal.JtaTransactionCoordinatorBuilderImpl</prop>
这也不起作用：
<prop key="hibernate.transaction.coordinator_class">jta</prop>
这也删除
<prop key="javax.persistence.transactionType">jta</prop>
但这也失败了。
