当你遇到这些问题时，你从哪里开始？我在开发环境中重现这些错误时遇到问题。
我们在树脂服务器上运行这段代码。我们有在事务中的线程中运行的插件。
我们有一些代码可以刷新 session ，有些则不能。是否有一些日志记录提供比这更有用的信息。

最佳答案
不是真正的答案，但请查看:http://community.jboss.org/thread/170092 (如果你还没有看到那个帖子)
关于java - org.hibernate.exception.JDBCConnectionException : could not insert, 如何在生产环境中查找问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7362313/
