Infinite loop with spring-boot in a one to many relation

Question

In a rest application, I use spring boot with jpa.

I have a class Lodger

who have

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, m         


        

Answer 1

It happens when you have a cycle in return object and spring tries to serialize it to other type.

Try to create DTO or Value Object (simple POJO) without cycles from returned model and then return it.
