ManyToOne not mapped with the parent ID - spring

Question

I am trying to implement tests in my spring boot app, but I have problems with ManyToOne/OneToMany links.
It seems that the link from the subobject is not created, while I use CascadeType = ALL.
I tried creating it in the BusinesDomain.addSubdomain, adding "subDomain.domain(this);" but this causes a loop.
I found out other topics with the same error but non of them seem to cover my issue.
Could you please help me find out what seems to be the issue ?
Thanks a lot!
Here are my Entities
import lombok.AccessLevel;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.NonNull;
import lombok.Setter;
import lombok.experimental.Accessors;
#Accessors(fluent = true)
#Data
#Entity
#NoArgsConstructor
public class BusinessDomain {
#Setter(AccessLevel.NONE)
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;
#NonNull
#Column(unique=true)
private String name;
#OneToMany(mappedBy = "domain", cascade = CascadeType.ALL, orphanRemoval = true)
private Set<BusinessSubDomain> subDomains = new LinkedHashSet<>();
public void addSubDomain(BusinessSubDomain subDomain) {
subDomains.add(subDomain);
}
}
#Accessors(fluent = true)
#Data
#Entity
#NoArgsConstructor
public class BusinessSubDomain {
#Setter(AccessLevel.NONE)
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;
#ManyToOne(optional = false)
#JoinColumn(name = "business_domain_id", referencedColumnName="id")
private BusinessDomain domain;
}
My service class:
#Override
public BusinessDomain saveOrUpdate(BusinessDomain businessDomain) throws OrcaException {
try {
BusinessDomain domain = businessDomainRepository.findByName(businessDomain.name());
if(null == domain) {
// Repository class not overriden (extends CrudRepository<BusinessDomain, Long>)
return businessDomainRepository.save(businessDomain);
} else {
domain.description(businessDomain.description());
domain.subDomains(businessDomain.subDomains());
return businessDomainRepository.save(domain);
}
} catch (Exception e) {
throw new OrcaException(e);
}
}
And my Test:
#RunWith(SpringRunner.class)
#SpringBootTest
public class BusinessDomainTest {
#Test
#Transactional
public void createBusinessDomainWithSubDomain() throws OrcaException {
BusinessDomain passengerBusinessDomain = new BusinessDomain().name(DOMAIN_NAME).description(DOMAIN_DESCRIPTION);
BusinessSubDomain distributionBusinessSubDomain = new BusinessSubDomain().name(SUBDOMAIN_NAME)
.description(SUBDOMAIN_DESCRIPTION);
passengerBusinessDomain.addSubDomain(distributionBusinessSubDomain);
businessDomainService.saveOrUpdate(passengerBusinessDomain);
BusinessDomain domain = businessDomainService.findByName(DOMAIN_NAME);
}
}
With this I get the error message:

Answer 1

Finally I understood.
First, the entity adder must be
public void addSubDomain(BusinessSubDomain subDomain) {
subDomains.add(subDomain);
subDomain.domain(this);
}
But this was causing an infinite loop with an infinite call to hash method.
I solved this (caused by lombok) using #Getter and #Setter instead of #Data in my entity.
Thanks
