Question

Let\'s I have entity A and entity B. Entity A have @OneToOne relationship with B.
I want do next:
if

Answer 1

The cascade from A to B should be placed on the field referencing B in class A, the cascade from B to A should be placed on the field referencing A in class B.

public class A {
    @OneToOne(cascade = {CascadeType.ALL})
    B b;
}

Should be in class A, as you want every action to be cascaded to B.

public class B {
    @OneToOne(cascade = {CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH})
    A a;
}

Should be in class B, as you only want certain actions cascaded to A
