注意：我无法通过各种场景在本地重现此问题。但是当我查看上面的生产服务器日志文件时，问题反复发生。我将其作为同步的代码块或者用于事务的服务层management.line实例？.save（flush：true）导致问题的确切...请让你的想法继续前进
答案 0 :(得分：1)
您绝对应该将数据库访问权限转移到事务性服务中。但这并不一定能阻止这个问题。此外，同步绝对不是这里的方式
这是乐观的锁定失败。 （见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，但根据我之前看到的情况，我怀疑您有双击问题：用户之前第二次触发操作第一个动作完成。第一个操作完成并更新受影响对象的版本。当第二个操作写入数据库时，它会失败，因为对象的版本自加载对象后已更新。
为了帮助验证是否存在问题，您应该将日志记录添加到生产系统，以便您可以查看此方法何时启动以及ID是什么。如果您看到同一对象的两个（或更多）日志条目具有几乎相同的时间戳，那么这就是您的问题。
要解决此问题，请修改网页以阻止双击或修改代码以接受StaleObjectStateException。
