无法使用 Hibernate 连接到 Informix
Posted
技术标签:
【中文标题】无法使用 Hibernate 连接到 Informix【英文标题】：Cannot connect to Informix using Hibernate 【发布时间】：2017-09-17 17:00:26 【问题描述】：我正在尝试使用 Hibernate 5.2.10 连接到 Informix 数据库，但程序没有响应并且卡住而没有抛出任何错误消息。
我在控制台中找不到任何东西。关于我犯了什么错误的任何建议？我是 Hibernate 的新手

【问题讨论】：
可能在 Ifx 连接后（在 openSession() 中）出现异常，但未在控制台中记录/转储。尝试连接到虚拟数据库或使用错误密码时是否出现异常？ 【参考方案1】：我使用 5.2 和最新的 jdbc 驱动程序进行了快速测试，它似乎对我来说工作正常。我正在使用您的 HibernateUtil 和类似的 Hibernate 配置文件：

我得到类似“挂起”的唯一方法是如果我在打开的 session() 期间遇到异常。我强制使用没有“经典”方法的旧 Hibernate 版本库 (3.x) 编译该方法：

和你一样，“最后一个”INFO 消息是“从 JdbcConnectionAccess 获得的连接”，但之后我也得到了 nosuchmethod 异常。我必须按 control+c 才能出去。
也许您的异常已发送到其他地方；）
编辑
这是我用来直接从控制台测试它的代码，应该是运行它所需的一切。

但我想它应该与您已经拥有的没有太大不同。
【讨论】：
我在其他任何地方都看不到我的异常，我使用的是 4.10.9 版本的 Informix JDBC 驱动程序。您使用的哪个版本可以正常工作？ JC8 和 JC9 之间的东西 ;) 刚刚用 JC9 测试过，它的工作原理是一样的。使用虚拟用户时是否看到异常？【参考方案2】：感谢您尝试帮助我。从休眠配置文件中删除此属性后，问题得到解决。
<property name="hbm2ddl.auto">update</property>

以上是关于无法使用 Hibernate 连接到 Informix的主要内容，如果未能解决你的问题，请参考以下文章
