StaleStateException：批量更新从更新 [0] 返回了意外的行数；实际行数：0；预期：1
StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1
我在这个网站上找到了太多的答案，但我无法解决错误。请帮我解决这个问题。
当(Transaction) tx.commit 执行时抛出异常但我不知道 why.If 我评论 tx.commit, Employee values will be inserted进入 table 但证书值不会插入证书 table.Please 检查它。
