Hi guys,

I'm new to spring and I'm trying to figure out if I'm doing something wrong or this is the way that spring-data-jpa behaves.

Let's say that I have an entity Customer where the primary key is called cid and it's an int. Also it is not auto_inc.

Therefore in my class I have something like that

Code:
@id
@Column(name="cid")
private int customerId;
Also, I have a repository that extends CrudRepository.
Now, let's say that I have already 3 customers with ids 1, 2, 3.

The strange this is that if I create a new customer and give him id=3, then I get no exception and the existing customer with id=3 is overwritten by the new one!
Also, if I edit customer with id=2 and change his id to 1, then again customer with id=1 is overwritten by the update of customer with id=2!!.

Thank you in advance
