我尝试使用findById方法按 id 获取行，但它没有成功，
无法在 DB 中找到行。当我findAll之前打电话时findById工作正常。我使用 PostgreSQL。

public void updateOffer(OrderOfferDTO orderOfferDTO) {

  //        List<OrderOfferEntity> all = orderOfferRepository.findAll();
        OrderOfferEntity orderOfferEntity = orderOfferRepository.findById(orderOfferDTO.getId()).orElse(null);

        assert(orderOfferEntity != null);

        if (!isCanOfferUpdate(orderOfferEntity)) return;

        orderOfferEntity.setNumberOffer(orderOfferEntity.getNumberOffer() + 1);
        orderOfferEntity.setOfferDelivery(orderOfferDTO.getOfferDelivery());
        orderOfferEntity.setOfferPickup(orderOfferDTO.getOfferPickup());

        orderOfferRepository.save(orderOfferEntity);
    }

存储库

@Repository
public interface OrderOfferRepository extends JpaRepository<OrderOfferEntity, Long> {
    OrderOfferEntity findByUserEntityAndOrderEntity(UserEntity userEntity, OrderEntity orderEntity);

    List<OrderOfferEntity> findByUserEntityNotAndOrderEntity(UserEntity supplierEntity, OrderEntity orderEntity);
    List<OrderOfferEntity> findByOrderEntity(OrderEntity orderEntity);
    List<OrderOfferEntity> findByUserEntity(UserEntity userEntity);
}

实体

@Entity
@Table(name = "AUCTION_SUPPLIER")
@Data
public class OrderOfferEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY) …

我有固定的列宽，需要使用apache POI自动调整行高，但我找不到它的工作决定。我尝试过这个决定，但它不适用于此文本

Lorem ipsum dolor sat amet，consectetur adipiscing elit，sed do eiusmod tempor incididunt ut laboure et dolore magna aliqua

列宽为33.00（236 像素），表格中的单元格具有换行文本属性。仅当内容高度大于现有行高度时，我才能更改行高度。

那么，我想问是否有任何方法或决定可以按内容自动调整行高？

private float calculateRowLinesForText(Font cellFont, float columnWidthInPoints, String value) {
        java.awt.Font currFont = new java.awt.Font(cellFont.getFontName(), 0, cellFont.getFontHeightInPoints());

        FontRenderContext frc = new FontRenderContext(null, true, true);

        int lineCnt = 0;
        for (String partValue : value.split("\n")) {
            AttributedString attrStr = new AttributedString(partValue);
            attrStr.addAttribute(TextAttribute.FONT, currFont);
            LineBreakMeasurer measurer = new LineBreakMeasurer(attrStr.getIterator(), frc);

            while (measurer.getPosition() < partValue.length()) …
