Java 处理批量更新时C3po和oracle的锁定情况

有时我的线程卡在这个状态，我认为db连接上有一个锁，所以我如何解决这个锁；这种情况发生在一个唯一的约束错误然后进入一个对每个记录处理的逐个方法时

在事务上发出回滚后，所有锁都应该消失。让我试试，我想它会工作的。是的，在添加事务注释后工作。有趣的一点是，当使用Welbogic数据源Jndi时，这段代码可以正常工作，不管怎样，永远是springboot:）在事务上发出回滚后，所有锁都应该消失。让我试试，我认为它可以工作是的，它在添加事务注释后工作。有趣的一点是，当使用Welbogic数据源Jndi时，这部分代码可以正常工作，不管怎样，永远是springboot:）
