Bidirectionnal relations go in infinite loop during check #633
Description
Hello,
It's been several times I go through this error :
I have two entities that know each other :
@Entity
public class CbdHardwareEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/* other properties */
@OneToOne(mappedBy = "cbd", fetch = FetchType.LAZY, cascade = CascadeType.REMOVE)
private CbdHardwareBomEntity bom;
}@Entity
public class CbdHardwareBomEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/* other properties */
@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "fk_cbd_id", referencedColumnName = "id", columnDefinition = "integer")
private CbdHardwareEntity cbd;
}And my tzatziki tests :
And that the CbdHardwareEntity entities will contain:
"""yml
- conceptionCode: 123456
"""
And that the CbdHardwareBomEntity entities will contain:
"""yml
- name: bom pace name
perimeter: perimeter pace
paceId: 50
cbd.id: 1
"""When I do a And the CbdHardwareEntity entities contain: to check the content of my main table after I called my service, it goes into an infinite loop :
com.fasterxml.jackson.databind.JsonMappingException: Document nesting depth (1001) exceeds the maximum allowed (1000, from `StreamWriteConstraints.getMaxNestingDepth()`) (through reference chain: com.decathlon.buysmart.datacost.hardware.repository.models.CbdHardwareEntity["bom"]->com.decathlon.buysmart.datacost.hardware.repository.models.CbdHardwareBomEntity["cbd"]->com.decathlon.buysmart.datacost.hardware.repository.models.CbdHardwareEntity["bom"]->com.decathlon.buysmart.datacost.hardware.repository.models.CbdHardwareBomEntity["cbd"]->com.decathlon.buysmart.datacost.hardware.repository.models.CbdHardwareEntity["bom"]->com.decathlon.buysmart.datacost.hardware.repository.models.CbdHardwareBomEntity["cbd"]-
I have tried the @JsonManagedReference and @JsonBackReference, it did work but I prefer not to modify my entities just to make tests work.
Do you have a solution to propose if I ever met this problem ? I will call my api to get resources to make the check I need; but it make more sense to directly check the content of a table.
Thanks
