avoid duplication with auto increment key in Hibernate
- by Lily
I am trying to use Hibernate to auto increment the id, however, I try to avoid duplication.
class Service
{
Long id; // auto increment
String name;
String owner;
// setter and getter
}
What I want to achieve is, whenever name and owner are the same, it will be a duplicated entry. In this case, I don't want to add another entry into the Database anymore. How to revise the hbm.xml files to avoid this issue?
