My entities as below

@Entity
public class A {

@ManyToOne
private B b;
}

@Entity
public class B {

@OneToMany
private Set c;
}

@Entity
public class C {
…
}

when I try
“select a from A a
left outer join fetch a.b b1
left outer join fetch b1.c c1

I can see there are lot of select c…

How can I avoid multiple round trip of c in this case?

I tried to use @BatchSize on B entity as well as C collection, still see lot of round trip call
