将 Hibernate 5.2 与 Spring 框架 4.x 集成答案

【问题标题】：Integrate Hibernate 5.2 with Spring framework 4.x将 Hibernate 5.2 与 Spring 框架 4.x 集成
【发布时间】：2016-10-05 17:32:57
【问题描述】：

我正在使用最新的稳定 Spring 版本 (4.2.6.RELEASE)。

在将 Hibernate 从 5.1 升级到 5.2 并将 hibernate-entitymanager 依赖项更改为 hibernate-core 后，由于休眠文档：https://github.com/hibernate/hibernate-orm/wiki/Migration-Guide---5.2

我没有收到任何编译错误，但我的所有测试都因此堆栈跟踪而失败：

【问题讨论】：

Spring 框架 4.3.0.RC2 可用，它支持 Hibernate 5.2。这是RC版本，但GA很快就会推出。您可以升级spring，但需要在GA可用时跟踪和更新

标签： java spring hibernate jpa

【解决方案1】：

Hibernate 5.2 支持在Spring framework 4.3 中添加，其稳定版本将在下周提供。 Spring 4.2 仅支持 Hibernate 到 5.1。

看到这个：

https://jira.spring.io/browse/SPR-14334

【讨论】：

【解决方案2】：

该问题仅与版本有关。将 Hibernate 版本 5.1.0 与 Spring 4.3.7 一起使用。它将解决这个问题。
将以下依赖项与 4.3.x 版本的 Spring 框架依赖项一起添加。

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>5.1.0.Final</version>
</dependency>`

【讨论】：

【解决方案3】：

方法是

applyFlushModeHint

protected boolean applyFlushModeHint(FlushMode flushMode)

Apply the FlushMode hint.

Parameters:
    flushMode - The FlushMode value specified as hint
Returns:
    true if the hint was "applied"

FlushMode 可以在哪里

总是在每次查询之前刷新会话。
AUTO有时会在查询执行之前刷新会话，以确保查询永远不会返回过时状态。COMMIT Session 在 Transaction.commit() 被调用时被刷新。
MANUAL 只有在 Session.flush() 被显式调用时，Session 才会被刷新应用程序。
从不已弃用。请改用 MANUAL。

【讨论】：

我不直接用这个方法。它由 Spring 事务管理器调用！这是否意味着我应该等待春季发布新版本以支持 Hibernate ORM 5.2？
你可以在这里阅读休眠文档。 docs.jboss.org/hibernate/orm/5.2/javadocs/overview-summary.html
试试 applyFlushModeHint 函数。
