Spring-boot, JPA, как сохранить коллекцию для объекта

Question

Я пытаюсь сохранить объект, который имеет коллекцию объектов, например, Invoice с коллекцией InvoiceItems.Я получил JSON с Invoice и InvoiceItems, но после сохранения только Invoice находится в базе данных InvoiceItems не сохраняются.

Invoice repository

import org.springframework.data.repository.Repository;

import java.util.List;

@org.springframework.stereotype.Repository
public interface InvoiceRepository extends Repository<GpInvoice, Long> {

    void save(GpInvoice invoice);
}

Контроллер

@PostMapping(path = "/new")
public void createInvoice(@RequestBody() InvoiceDto gpInvoice) {
    mInvoiceService.saveAndFlush(gpInvoice.invoice, gpInvoice.invoiceItems);
}

Сервис

@Override
@Transactional
public void saveAndFlush(GpInvoice invoice, List<GpInvoiceitem> gpInvoiceItem) {
    invoice.setGpInvoiceitemsByGpInvoiceRecid(gpInvoiceItem);
    mInvoiceRepository.save(invoice);
}

Почему InvoiceItems не сохраняются?

Answer 1

Учитывая ситуацию, я думаю, что вам не хватает "(cascade = CascadeType.ALL)".Вот как должно выглядеть ваше сопоставление OneToMany -

            @OneToMany(mappedBy = "gpInvoiceByGpInvitInvoicerecid", cascade=CascadeType.ALL)
            public Collection<GpInvoiceitem> getGpInvoiceitemsByGpInvoiceRecid() {
                return mGpInvoiceitemsByGpInvoiceRecid;
            }
