Hibernate 5 id uniqueness

Question

In Hibernate 5 is it a problem if I use the same id value in different tables?

I have two entities with this annotation:

@Id
@Column(name = "ID")
public String getId()
{
     return id;
}

If I call session.get(MyClass.class, "theId") I can get the right entity?

Answer 1

Yes, you can create such mappings because

• two classes in Java may have a field with the same name
• two tables in database may have a column with the same name

There is nothing else to it.
