I use Hibernate with Spring. I have marked a table called Person with First_Name and Last_Name as unique. I used Springs transaction manager and have marked the service layer method to rollback for Exception.class
I can see that the create(Person person) works and Spring is able to catch if a unique constraint violation happens. However my update(Person) which is exactly of same nature does not. The update code completes and somewhere down the line I get a strack trace such as this.
Why does it work for create though? How is update's transaction different from create. ? Is there anything else that needs to be configured via annotation or in the applicationContext.xml?
Any thoughts will be helpful.
