Question

你好，我在Spring批处理应用程序中遇到了hibernate错误

ERROR: org.springframework.batch.core.job.AbstractJob - Encountered fatal error executing job
org.springframework.dao.OptimisticLockingFailureException: Attempt to update job execution id=33 with wrong version (0), where current version is 1

根据错误日志，我在Abstract Job Class（由Spring Batch提供）遇到代理错误我想因为Abstract Job Class没有任何非参数构造函数，所以CGLIB不能提供任何代理类。
如何解决这个问题？
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

表示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，这将导致spring表也是不一致的状态=＆gt;发生乐观锁定。

尝试为hibernate添加日志记录并显示实际的sql。这可能有助于您找出问题的实际位置。

Spring Batch中的启动作业发生了Hibernate代理错误
