我在让 liquibase 在我的 Spring Web 应用程序中使用 atomikos 时遇到问题。在我尝试将 liquibase 添加到混合物中之前，该项目运行良好。当我为我的项目配置 liquibase 时，我看到了一个异常。关键是它说的地方：

原因：com.atomikos.jdbc.AtomikosSQLException：连接已关闭 - 不再允许调用 hashCode！

Liquibase 正在尝试在已关闭的 JDBC 连接上调用 hashCode()。我试图弄清楚是否有一种方法可以配置 Atomikos（或者可能是 Hibernate？）以保持连接打开足够长的时间让 liquibase 做它的事情？

有人有使用 liquibase + atomikos 的经验吗？

这是堆栈跟踪：

以下是一些有关根本原因的其他详细信息。

在 liquibase 发挥它的魔力之后，它会关闭数据库连接（一切都很好）。然后它尝试通过调用从 ConcurrentHashMap 中删除关联的“执行程序”实例ConcurrentHashMap#remove(Object key)，其中映射的键是数据库连接对象。

当然，此时哈希映射必须计算密钥上的哈希码。这就是我们遇到 Atomikos 问题的地方。

在这种情况下，键是 AtomikosConnectionProxy 的一个实例。尝试调用 hashCode() 会导致调用该AtomikosConnectionProxy#invoke(Object proxy, Method method, Object [] args)方法。该方法中的逻辑只允许在数据库连接关闭后调用 getInvocationHandler、reap 和 isClosed 方法。连接关闭后的任何其他方法调用都会导致上述异常。

如果您希望 liquibase 使用现有的 Atomikos 代码，则 liquibase 必须在关闭连接之前从映射中清除执行程序。
