注：我无法通过各种scenario.but当本地重现此问题我查看生产服务器日志文件上面的问题不断发生。让我把它的代码块同步一个或其他服务层的事务management.line实例？.save（flush：true）导致问题确切..请给你的想法前进

Answer 1

你一定要移动你的数据库访问到一个交易服务。尽管如此，这并不一定会阻止这个问题。此外，同步绝对不是这里的方式

这是一个乐观锁定失败。 （请参阅https://grails.github.io/grails-doc/latest/guide/GORM.html#locking）

根据您提供的信息，我无法提供明确的答案，但基于之前所见，我怀疑您有双击问题：用户正在触发在第一个动作完成之前再次执行动作。第一个操作完成并更新受影响对象的版本。当第二个动作写入数据库时​​，它会失败，因为对象的版本在对象加载后已更新。

为了帮助验证这是否是问题，您应该将日志记录添加到您的生产系统，以便您可以看到此方法何时启动以及标识是什么。如果您看到具有几乎相同时间戳的同一对象的两个（或更多）日志条目，那么这就是您的问题。

要解决它，请修改您的网页以阻止双击或修改您的代码以接受StaleObjectStateException。
