Spring Boot JPA - OneToMany relationship causes infinite loop

Question

I have a two objects with simple @OneToMany relationship which looks as follows:

parent:

@Entity
public class ParentAccount {

  @Id
  @GeneratedValu         


        

Answer 1

As the first answer suggests:

Do not use Lombok's @Data annotation on @Entity classes.

Reason: @Data generates hashcode(), equals() and toString() methods that use the generated getters. Using the getter means of course fetching new data even if the property was marked with FetchType=LAZY.

Somewhere along the way hibernate tries to log the data with toString() and it crashes.
