default value for CascadeType in Hibernate

Question

I am using Hibernate to persist this bean.

import javax.persistence.*;  @Entity public class Person {     @Id @GeneratedValue     private int id;     @Column     private String name;     @OneToOne     private Address addr; } 

What is the CascadeType for addr?

Answer 1

CascadeType defaults to the empty array . See CascadeType in Annotation Type OneToOne

By default no operations are cascaded.

Answer 2

You can check the source of @OneToOne at here . No operations are cascaded by default

  /**      * (Optional) The operations that must be cascaded to       * the target of the association.      *      * <p> By default no operations are cascaded.      */    CascadeType[] cascade() default {};
