In Spring Boot @prepersist und @CreatedBy verursachen den gefundenen gemeinsamen Referenzfehler ⇐ Java

[Guest]

Ich habe zwei Einheiten, die eine bidirektionale Beziehung des Onetomany -Relations haben, wie unten gezeigt: < /p>

Code: Select all

@Data
@Accessors(chain = true)
@Builder
@Entity
@FieldDefaults(level = AccessLevel.PRIVATE)
@AllArgsConstructor
@NoArgsConstructor
@Table(name = "refund_initiates")
public class RefundInitiate extends BaseEntityV3 {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
Integer id;

//    ... other fields

@OneToMany(mappedBy = "refundInitiate", cascade = CascadeType.ALL, orphanRemoval = true)
List refundLedgers = new ArrayList();
}
< /code>
@Data
@Accessors(chain = true)
@AllArgsConstructor
@NoArgsConstructor
@Table(name = "refund_ledger")
@Entity
@Builder
public class AutomatedRefundLedger extends BaseEntityV3 {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
Integer id;

// ... Other Fields

@ManyToOne
@JoinColumn(name = "refund_initiate_id", nullable = false)
RefundInitiate refundInitiate;
}
< /code>
As you see both are extending a base entity BaseEntityV3, this is an abstract class for audit purpose:
@Getter
@Setter
@ToString
@FieldDefaults(level = AccessLevel.PRIVATE)
@AllArgsConstructor
@NoArgsConstructor
@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public class BaseEntityV3 {

@CreatedBy
@Column(name = "created_by")
Integer createdBy;

@CreatedDate
@Column(name = "created_on")
Date createdOn;

@LastModifiedBy
@Column(name = "updated_by")
Integer updatedBy;

@LastModifiedDate
@Column(name = "updated_on")
Date updatedOn;

@Column(name = "is_deleted")
Boolean deleted = Boolean.FALSE;
}
< /code>
This class is using @CreatedBy, @LastModifiedDate and other JPA Audit annotations.
Below we have AuditorAwareConfig

Klasse:

Code: Select all

@Configuration
@EnableJpaAuditing(auditorAwareRef = "userIdAuditorProvider")
public class AuditorAwareConfig {

@Bean(name = "userIdAuditorProvider")
public AuditorAware userIdAuditorProvider() {
return new AuditorAwareImpl();
}
}

@Component
class AuditorAwareImpl implements AuditorAware {

@Autowired
EmployeeRepository employeeRepo;

@Override
public Optional getCurrentAuditor() {
try {
final Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
return Optional.of((principal instanceof UserDetails)
? this.getEmployeeId(((UserDetails) principal).getUsername())
: 1);
} catch (Exception e) {
return Optional.of(1);
}
}

private Integer getEmployeeId(String username) {
// TODO: Remove TEST CODE
return employeeRepo.findFirstByUsername(username).map(Employee::getId).orElse(1);
}
}
< /code>
Now here's the issue:
public AutomatedRefundLedger updateAutomatedRefundLedger(AutomatedRefundLedgerReq updateReq) {

AutomatedRefundLedger existingLedger = automatedRefundLedgerRepo.findById(updateReq.getId()).orElseThrow();

// Updates the fields of existingLedger (doesnt save it in DB)
this.updateFieldOfExistingLedger(existingLedger, updateReq);

// Saving the changes: This is where I get the error
return automatedRefundLedgerRepo.save(existingLedger);
}
< /code>
While saving the change I get error saying that:
[Request processing failed; nested exception is org.springframework.orm.jpa.JpaSystemException: Found shared references to a collection: payments.module.data.model.RefundInitiate.refundLedgers; nested exception is org.hibernate.HibernateException: Found shared references to a collection: payments.module.data.model.RefundInitiate.refundLedgers] with root cause

org.hibernate.HibernateException: Found shared references to a collection: payments.module.data.model.RefundInitiate.refundLedgers
< /code>
If I remove the JPA audit annotation like @CreatedBy, @CreatedDate, @LastModifiedBy and @LastModifiedDate, then it will work fine, also if I remove the extend BaseEntityV3

von beiden. Es verwendete manuell @prepersit und @PreUpdate und verwendete eine statische Klasse, um IDs von Mitarbeitern zu erhalten, aber immer noch den gleichen Fehler, den ich bekam. Da ich in den neuesten Fehler keinen solchen Fehler erhalte, wird hier die Version des Springboot verwendet: < /p>

Code: Select all

id 'org.springframework.boot' version '2.3.4.RELEASE'
