PersistentObjectException: Uninitialized proxy passed to persist - spring

Question

I am working with Spring Data JPA and an MySQL database for a records management system. Below are two entities that I have modeled and I am trying to persist a Policy record to the database:
Policy Entity:
public class Policy {
private String policyNumber;
private String policyName;
private Steward steward;
private PolicyHolder policyHolder;
#Id
#Column(length = 30)
public String getPolicyNumber() {
return policyNumber;
}
public void setPolicyNumber(String policyNumber) {
this.policyNumber = policyNumber;
}
#Column(length = 80)
public String getPolicyName() {
return policyName;
}
public void setPolicyName(String policyName) {
this.policyName = policyName;
}
#OneToOne(cascade = ALL, mappedBy = "policy", orphanRemoval = true, optional = false)
public PolicyHolder getPolicyHolder() {
return policyHolder;
}
}
PolicyHolder Entity:
#Entity
public class PolicyHolder extends PolicyMember {
private Policy policy;
public PolicyHolder() {
super();
}
#OneToOne
#JoinColumn(name = "policy_policyNumber", referencedColumnName = "policyNumber")
public Policy getPolicy() {
return policy;
}
public void setPolicy(Policy policy) {
this.policy = policy;
}
#Override
public String toString() {
return "PolicyHolder{" +
"policy=" + policy +
"} " + super.toString();
}
}
PolicyMember Entity:
#Entity
public abstract class PolicyMember {
private CompositePolicyMemberPK policyMemberId;
private String firstname;
private String surname;
private LocalDate dateOfDeath;
private LocalDate dateOfBirth;
private MemberStatus status;
private BillingStatus billingStatus;
private String nationalId;
private LocalDateTime creationDate;
private Gender gender;
private String msisdn;
private LocalDate closureDate;
private String createdBy;
private String memberType;
private PackageBenefit packageBenefit;
private List<DependantTransferRequest> transferRequests;
#EmbeddedId
public CompositePolicyMemberPK getPolicyMemberId() {
return policyMemberId;
}
public void setPolicyMemberId(CompositePolicyMemberPK policyMemberId) {
this.policyMemberId = policyMemberId;
}
#Column(length = 50)
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
#Column(length = 50)
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
#Convert(converter = MemberStatusConverter.class)
public MemberStatus getStatus() {
return status;
}
public void setStatus(MemberStatus status) {
this.status = status;
}
#Convert(converter = BillingStatusConverter.class)
public BillingStatus getBillingStatus() {
return billingStatus;
}
public void setBillingStatus(BillingStatus billingStatus) {
this.billingStatus = billingStatus;
}
#Column(length = 20)
public String getNationalId() {
return nationalId;
}
public void setNationalId(String nationalId) {
this.nationalId = nationalId;
}
#Enumerated(EnumType.STRING)
public Gender getGender() {
return gender;
}
public void setGender(Gender gender) {
this.gender = gender;
}
#Column(length = 15)
public String getMsisdn() {
return msisdn;
}
public void setMsisdn(String msisdn) {
this.msisdn = msisdn;
}
#Column(length = 50)
public String getCreatedBy() {
return createdBy;
}
public void setCreatedBy(String createdBy) {
this.createdBy = createdBy;
}
#Column(name = "memberType", insertable = false, updatable = false)
public String getMemberType() {
return memberType;
}
public void setMemberType(String memberType) {
this.memberType = memberType;
}
#OneToOne(mappedBy = "policyMember", optional = false, cascade = CascadeType.ALL)
public PackageBenefit getPackageBenefit() {
return packageBenefit;
}
public void setPackageBenefit(PackageBenefit packageBenefit) {
this.packageBenefit = packageBenefit;
}
public LocalDate getDateOfDeath() {
return dateOfDeath;
}
public void setDateOfDeath(LocalDate dateOfDeath) {
this.dateOfDeath = dateOfDeath;
}
public LocalDate getDateOfBirth() {
return dateOfBirth;
}
public void setDateOfBirth(LocalDate dateOfBirth) {
this.dateOfBirth = dateOfBirth;
}
public LocalDate getClosureDate() {
return closureDate;
}
public void setClosureDate(LocalDate closureDate) {
this.closureDate = closureDate;
}
public LocalDateTime getCreationDate() {
return creationDate;
}
public void setCreationDate(LocalDateTime creationDate) {
this.creationDate = creationDate;
}
#OneToMany(orphanRemoval = true, mappedBy = "dependantToTransfer")
public List<DependantTransferRequest> getTransferRequests() {
return transferRequests;
}
public void setTransferRequests(List<DependantTransferRequest> transferRequests) {
this.transferRequests = transferRequests;
}
}
Composite Key:
#Embeddable
public class CompositePolicyMemberPK implements Serializable {
private String policyNumber;
private String suffixNumber;
private static final long serialVersionUID = 1L;
public CompositePolicyMemberPK(String policyNumber, String suffixNumber) {
super();
this.policyNumber = policyNumber;
this.suffixNumber = suffixNumber;
}
public CompositePolicyMemberPK() {
super();
}
#Column(length = 30)
public String getPolicyNumber() {
return this.policyNumber;
}
public void setPolicyNumber(String policyNumber) {
this.policyNumber = policyNumber;
}
#Column(length = 2)
public String getSuffixNumber() {
return this.suffixNumber;
}
public void setSuffixNumber(String suffixNumber) {
this.suffixNumber = suffixNumber;
}
#Override
public boolean equals(Object o) {
if (o == this) {
return true;
}
if (!(o instanceof CompositePolicyMemberPK)) {
return false;
}
CompositePolicyMemberPK other = (CompositePolicyMemberPK) o;
return (getPolicyNumber() == null ? other.getPolicyNumber() == null : getPolicyNumber().equals(other.getPolicyNumber())) && (getSuffixNumber() == null ? other.getSuffixNumber() == null : getSuffixNumber().equals(other.getSuffixNumber()));
}
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + (getPolicyNumber() == null ? 0 : getPolicyNumber().hashCode());
result = prime * result + (getSuffixNumber() == null ? 0 : getSuffixNumber().hashCode());
return result;
}
#Override
public String toString() {
return this.getPolicyNumber() + "-" + this.getSuffixNumber();
}
}
The code that is responsible for persisiting the policy is as follows:
public Subscriber addMemberToSteward(Long stewardId, Subscriber subscriber) {
Steward steward = this.findStewardById(stewardId);
if(steward == null){
throw new EcosureException(String.format("No steward found with id '%s'.",stewardId));
}
final BillingStatus billingStatus = BillingStatus.REG_IN_PROGRESS;
final MemberStatus memberStatus = MemberStatus.NEW;
final ProductPackage product = productService.findPackageById(subscriber.getProductPackageId());
subscriber.setNationalId(nationalIDNumberUtils.formatIdNumber(subscriber.getNationalId()));
final PolicyHolder policyHolder = convertToPolicyHolder(subscriber, product, billingStatus, memberStatus);
Policy policy = getPolicyFromSubscriberInfo(subscriber, policyHolder);
policy.setSteward(steward);
policy.setStatus(PolicyStatus.NEW);
System.out.println("Policy Holder" + policyHolder);
policyRepository.save(policy);
return subscriber;
}
The getPolicyFromSubscriberInfo method is below:
private Policy getPolicyFromSubscriberInfo(final Subscriber subscriberInfo, final PolicyHolder policyHolder) throws {
final Policy policy = new Policy();
policy.setMsisdn(subscriberInfo.getMsisdn());
policy.setPolicyNumber(policyNumberGenerator.getNextPolicyNumber());
policy.setPolicyName(policyHolder.getFirstname() + " " + policyHolder.getSurname());
policyHolder.setPolicy(policy);
CompositePolicyMemberPK policyMemberId = new CompositePolicyMemberPK();
policyMemberId.setPolicyNumber(policy.getPolicyNumber());
policyMemberId.setSuffixNumber(policyNumberGenerator.getNextSuffix(policy.getPolicyNumber(),true));
policyHolder.setPolicyMemberId(policyMemberId);
policy.setPolicyHolder(policyHolder);
return policy;
}
The PolicyRepository is shown below:
public interface PolicyRepository extends JpaRepository<Policy, String> {
}
When I try to persist a Policy entity I am getting the error below:
