Question

I just want to know if transitive relation(i don’t know if it can be called so) can be persisted in hibernate using annotations.
ie, i have 3 pojo classes namely A,B and C.
i just map C’s instance into B and B’s instance into A.
when i save A (session.save(A)), can i get B and C persisted?

For example:

a = new A();

b = new B();

c = new C();

b.setC(c);

a.setB(b)

then,

session.save(a);

if the above line execute, i just want to know whether b and c would get persisted?

i think all of you got it what i meant.
Else, i can more elaborate my problem..
Please help me..
Thanks in advance.

Answer 1

You can define what object to save along with your current object. In your case

For A When A is saved, save the B object along with it.

public class A {
    @ManyToOne(cascade={CascadeType.PERSIST})
    B b;
}

For B When B is saved, save the C object automatically along with it

public class B {
    @ManyToOne(cascade={CascadeType.PERSIST})
    private C c;
}

For C (Nothing to save along with it)

public class C {

}
