이런 오류가 발생하네.

 

원인은 아래처럼 Embadeable 클래스를 만들었는데..

그것을 사용하는 쪽에서 객체를 잘못 생성해서 발생하는 원인 이었음.

import jakarta.persistence.Embeddable;
import lombok.Getter;

@Embeddable
@Getter
public class Address {

    private String city;
    private String street;
    private String zipcode;

    protected Address() {
    }
    public Address(String city, String street, String zipcode) {
        this.city = city;
        this.street = street;
        this.zipcode = zipcode;
    }

}

 

잘못사용한 예

    @Embedded
    private String address;

 

올바르게 사용한 예

    @Embedded
    private Address address;
