Bulk Insert Entity

The BulkInsertEntity abstract class is designed to facilitate bulk insert operations in JPA entities.

It provides common fields and functionality required for bulk inserts, allowing entities to be saved in batches using saveAll method provided by JpaRepository.

Usage

To use the BulkInsertEntity abstract class:

1. Create your entity class by extending BulkInsertEntity.
2. Use JpaRepository provided by Spring Data JPA to save entities in bulk using the saveAll method.

BulkInsertEntity

@Getter
@ToString
@MappedSuperclass
@Audited
@EntityListeners(AuditingEntityListener.class)
public abstract class BulkInsertEntity implements Persistable<Long> {

    @Transient
    private boolean isNew = true;

    @Override
    public boolean isNew() {
        return isNew;
    }

    @PostLoad
    private void markIsNotNew() {
        isNew = false;
    }

    @CreatedDate
    @Column(nullable = false, updatable = false)
    protected LocalDateTime createdDatetime;

    @LastModifiedDate
    @Column(nullable = false)
    protected LocalDateTime updatedDatetime;

    @CreatedBy
    protected Long createdBy;

    @LastModifiedBy
    protected Long updatedBy;

}

Example

@Entity
@Getter
@ToString
@Builder
@AllArgsConstructor(access = AccessLevel.PROTECTED)
@NoArgsConstructor(access = AccessLevel.PROTECTED)
@Table(name = "Books")
public class Book extends BulkInsertEntity {

    @Id
    @Column
    private Long bookSeq;

    @Column
    private String title;

    @Column
    private String author;

    @Column
    private LocalDateTime publicationDate;

    @Column(precision = 20, scale = 5)
    private BigDecimal price;

    @Override
    public Long getId() {
        return bookSeq;
    }

}

public interface BookRepository extends JpaRepository<Book, Long> {
    // No additional methods required
}

@Service
public class BookService {

    private final BookRepository repository;

    @Autowired
    public BookService(BookRepository repository) {
        this.repository = repository;
    }

    public void saveEntitiesInBulk(List<Book> entities) {
        repository.saveAll(entities);
    }
}
