您好，我在 Spring 批处理应用程序中遇到休眠错误

根据错误日志，我在抽象作业类（由 Spring Batch 提供）遇到代理错误
我猜由于抽象作业类没有任何非参数构造函数，CGLIB 无法提供任何代理类。
我该如何解决这个问题问题？

我现在正在使用 spring batch admin

那个例外

org.springframework.dao.OptimisticLockingFailureException: Attempt to update job execution id=33 with wrong version (0), where current version is 1

意味着由于某种原因您的步骤事务锁定失败。

可能导致您的业务逻辑事务被设置为 RollbackOnly 模式，这会导致弹簧表的状态也不一致 => 发生乐观锁定。

尝试为休眠添加日志记录并显示实际的 sql。这可能会帮助您找出问题所在。
