How I treat a Unique field when it’s time to update with Hibernate.
It features duplicate field msg.
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '41987523699' for key 'UK_4yakf5drp3py7vaalfeb1mrv7'
A little more about UNIQUE: It is possible to have more than one Primary key in a table?
