Spring，迁移到hibernate4，由于关闭连接，Interceptor无法正常工作

Question

我正在尝试将Hibernate的使用升级到Hibernate 4。

我们有一堆Hibernate拦截器。这些使用了界面

public void beforeTransactionCompletion(Transaction tx)

接线完全正确，可在Hibernate3中使用。但是，通过对H4实用程序类的适当更改，它不会。

原因似乎是在调用接口之前数据库连接已关闭，因此我们得到了“连接已关闭”异常。

挖掘源代码，这似乎是因为在'triggerBeforeCompletion'的机制中，连接确实被关闭了。这似乎归结为 DataSourceUtils.beforeCompletion，它有以下注释：

// Release Connection early if the holder is not open anymore
// (that is, not used by another resource like a Hibernate Session
// that has its own cleanup via transaction synchronization),
// to avoid issues with strict JTA implementations that expect
// the close call before transaction completion.

在交易完成之前确保我的连接没有关闭的正确方法是什么？

    return properties;
