我的Transactional Service中有一个方法可以验证对象并保存它。在此保存期间假设由于“子”对象中的垃圾数据 - 抛出DataException。
这是一个RuntimeException，Hibernate触发回滚。我从日志中验证了如下所示。
当我在Action中捕获异常时，我看到Session中的“child”对象具有与之关联的标识符。为什么会这样？
当用户更正该值并尝试再次保存该对象并且hibernate尝试更新该对象时，会导致出现问题，导致批量更新StaleStateException。
我找到了一个描述确切问题{{3}}的博客。我有什么解决方案吗？是使用合并的出路？ hibernate.use_identifier_rollback = true help？

查看类似问题的答案：It's not a bug, but a feature
总而言之，生成 id 的过程是无事务的，因此即使发出回滚，生成的 id 也不会“未生成”。
我遇到了基本相同的问题，我尝试设置 hibernate.use_identifier_rollback=true 但无济于事。该属性的文档指出，如果实体被移除，Hibernate 将清除 id，但事实并非如此。
当我知道它是一个新实体时，我通过使用 persist() 解决了这个问题，否则使用 merge()。请注意，即使您的实体已经具有生成的 ID，persist() 也会起作用。
