Spring 数据 JPA + H2 嵌入式持久性：CrudRepository.save 仅在重新启动时保存到内存中不再看到更改
Spring Data JPA + H2 embedded persistence : CrudRepository.save saves only to memory on restart no longer see the changes
我有一个带有 h2 嵌入式持久性的简单 Spring Data JPA 设置。我创建了一堆实体并设置 spring.jpa.hibernate.ddl-auto=update 因为我只打算将它用作轻量级嵌入式持久性机制并且不 need/want 手动定义模式或担心模式迁移等（因为此数据不会迁移）。
现在，当我执行 CrudRepository.save 时，它可以完美运行，随后 find 调用 return 保存的实体。我也可以在 H2 控制台的休眠自动创建 tables 中看到这些。
然而，奇怪的是，当我重新启动服务时，一些更改消失了。当我稍微挖掘一下时，我发现这只发生在与封闭的 'parent' 实体处于 @OneToMany 关系中的实体。
例如，在下面的示例中，此问题仅发生在 IpInterface 实体中，当我添加另一个 IpInterface 实体并从 enclosingContainerRepository.save() 保存时。我看到一切正常，新的 IpInterface 也显示在控制台的 table 中。但是当我重新启动服务时，新的 IpInterface 实体就消失了。但是，如果我添加一个新的 EnclosingContainer 实体，该实体会在服务重新启动时正确保留。
我也尝试使用 JpaRepository 和它的 saveAndFlush 得到相同的结果。
有人知道为什么会这样吗？
public interface EnclosingContainerRepository extends CrudRepository<EnclosingContainer, String> {
...
...
}
@Entity
public class EnclosingContainer implements Serializable {
...
...
@Id
private String ipAddress;
@OneToOne(cascade = CascadeType.ALL, orphanRemoval=true)
private SomeDTO someDTO;
@OneToMany(cascade=CascadeType.ALL, orphanRemoval=true)

@Entity
public class SomePort implements Serializable {

更新（2020 年 11 月 22 日）：
伙计们，打扰了，我想这是我在更新 parent 实体时所做的愚蠢事情的原因，该实体的 ID 与我在应用程序启动时测试编辑操作时使用的 ID 相同（错过了删除 post 我的初始验证）导致更改的外观在重新启动后不会持续存在。当我删除它时，它就像 breeze.
感谢每一位看过的人。特别感谢@Shawrup 关于检查启动时发生的事情的有用说明，这帮助我意识到我正在做的错误。
只想回答并关闭这个。
事实证明，问题是因为我的测试代码更新了我在启动时测试编辑操作时使用的同一实体，这使得更改看起来不会在重新启动后持续存在，而实际上它们确实存在。
感谢@Shawrup 通过查看启动日志帮助我发现问题。
谢谢

更新（2020 年 11 月 22 日）： 伙计们，打扰了，我想这是我在更新 parent 实体时所做的愚蠢事情的原因，该实体的 ID 与我在应用程序启动时测试编辑操作时使用的 ID 相同（错过了删除 post 我的初始验证）导致更改的外观在重新启动后不会持续存在。当我删除它时，它就像 breeze.
感谢每一位看过的人。特别感谢@Shawrup 关于检查启动时发生的事情的有用说明，这帮助我意识到我正在做的错误。
只想回答并关闭这个。
事实证明，问题是因为我的测试代码更新了我在启动时测试编辑操作时使用的同一实体，这使得更改看起来不会在重新启动后持续存在，而实际上它们确实存在。
感谢@Shawrup 通过查看启动日志帮助我发现问题。
谢谢
