mysql - ConstraintViolationException 未显示约束名称 MySQL

Question

我正在尝试将记录保存在具有多个唯一约束的表中。其中之一称为 UK_ESTABLISHMENT_REGISTERS_003，基于 2 列。

当用户尝试在表中输入重复值时，会引发约束冲突异常，但我无法检索约束名称以显示有意义的错误消息。根错误仅显示:键 4 的重复条目 '2-3'
我需要约束名称而不是键 4。
为了获得要解析的约束名称，我需要做什么配置？
代码栈如下:

任何帮助将非常感激。我正在使用 hibernate 3.6、mysql 服务器 5 和 spring 框架 3
