[英]JPA unique constraint validation
How to validate Multiple column unique constraint in JPA entity. 如何在JPA实体中验证多列唯一约束。 Is there any Hibernate validator for this purpose.
是否有用于此目的的Hibernate验证器。 I have added @UniqueConstraint annotation.
我添加了@UniqueConstraint注释。 But it is not doing any validation.And I also want to customize the error message.
但它没有进行任何验证。我还想自定义错误消息。
The @UniqueConstraint
is not related to hibernate-validator. @UniqueConstraint
与hibernate-validator无关。 It cannot be handled by java-only validation, it needs a trip to the database. 它不能通过仅Java验证来处理,它需要访问数据库。
It tells hibernate that the database has a unique constraint. 它告诉hibernate数据库有一个唯一的约束。 If the database does not have a unique constraint, I think the insert should pass.
如果数据库没有唯一约束,我认为插入应该通过。
