我有一个在 spring 和 hibernate 3.0 上开发并部署在 apache tomcat 6 上的 Web 应用程序。当我尝试将数据插入到表之一（'CAR_ATTRIBUTE'表）时，我遇到了错误。

此错误只能在生产环境中重现。相同的代码在我的本地环境中工作，指向相同的数据库。我尝试添加记录器语句，发现序列生成器每次都生成相同的值，即“0”。等待您的帮助。

谢谢您的回复。是的，异常清楚地表明它违反了约束。CARS.XAK1CAR_ATTRIBUTE 是组合键，它应该是唯一的。我已经验证了所有数据（通过记录器）并且找不到可能违反此约束的数据。此外，如果它违反了这个约束，那么它不应该在我指向同一个数据库的本地环境中工作。这可以特定于服务器吗？如果可以帮助解决问题，我可以提供更多详细信息，例如表 DDL 和我要插入的数据。——桑托什

这似乎是休眠缓存的问题......在单个缓存刷新中，您无法更新两次包含集合的对象。尝试在代码末尾添加 session.flush() ...

在不了解您在此保存中具体做什么的情况下，我只能说答案在堆栈跟踪中

unique constraint (CARS.XAK1CAR_ATTRIBUTE) violated

你违反了某种约束。当您打算更新时，也许您正在保存？

我尝试使用 session.flush 解决方案，但我仍然面临同样的问题 -

然后我尝试了下面的事情 - 在我的 id 列上有 updatable=false - 现在它似乎对我有用 - 你可以试试这个解决方案，看看它是否有效

@Id
@Column(name = "MY_COLUMN_NAME",unique=true,nullable=false,updatable=false)
@GeneratedValue(strategy=GenerationType.SEQUENCE,generator="MY_SEQ_GEN" )
private Integer id;
