Question

我将 Spring 4.3.4.RELEASE 与 Hibernate 5.1.15
一起使用作为从3到5的休眠迁移的一部分，我面临与事务注释相关的一些问题。

请考虑一种方法包含两种带有/不带有事务注释的不同方法的情况。
在休眠3中，它曾经可以正常工作。但是在升级到休眠5方法后，setEMSStatus失败了，因为subscribedEms为空。

createAndSaveSubscribedEms不会将数据刷新到数据库。因此，setEMSStatus不会从数据库获取数据，因此会为null。

显式添加冲洗将起作用。但是，可能有100个地点的情况类似。因此添加显式刷新似乎不是可行的解决方案。

//Class1
@Transactional(rollbackFor = Exception.class)
public void validateAndSave(List<EmsDto> gridList) {
    //Removing unnecessary code
    emsEntityManager.createAndSaveSubscribedEms(EmsDto.getMessageName(), EmsDto.getDescription(), SubscribeEmsStatus.UNKNOWN.toString());
    //Removing unnecessary code
    emsEntityManager.setEMSStatus(entry.getKey(), SubscribeEmsStatus.VALID.toString());
}

//Class2
@Transactional
public void createAndSaveSubscribedEms(final String messageName, final String description, final String status) {
    session.save(SubscribedEms.create(messageName, description, status));
}
// Note: No transactional and it was working earlier in hibernate 3 
public void setEMSStatus(String emsName, String newStatus) {
    SubscribedEms subscribedEms = (SubscribedEms) session.createCriteria(SubscribedEms.class).
        add(Restrictions.eq(SubscribedEms_.messageName, emsName)).
        uniqueResult();
    subscribedEms.setStatus(newStatus);
}

我遇到了类似的问题 https://www.javacodegeeks.com/2013/03/migrating-from-hibernate-3-to-4-with-spring-integration.html
但是在休眠5.1.17中，我看不到该类本身。

我应该进行哪些更改才能使其正常工作？

我启用了日志以查看使用了哪种事务管理器。

session.getTransaction（）。getStatus（）是 NOT_ACTIVE
session.getFlushMode（）是 AUTO
***** jtaTransactionManager有什么问题吗？ ****

Spring-@Transactional-什么时候刷新数据？
