org.springframework.dao.DataIntegrityViolationException

while adding some data to 开发者_StackOverflow社区table from jsp, only one row of data gets inserted

Also an org.springframework.dao.DataIntegrityViolationException is thrown.

Can you say why this exception is raised?


The exception is in most cases about database constraint violation. - In your case I would guess it is some unique constraint - but this is only guessing.
