本文介绍了我累了要用JpaRepository做一些事，但是用findById找不到行，的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试使用findById方法按ID获取行，但它不成功
在DB中找不到行.当我在findById之前调用findAll时，一切正常.我使用PostgreSQL.
I have tried to get row by id with findById method but it it not succeed
can't find row in DB . and when I call findAll before findById it's work fine.I use 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

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

推荐答案
您的所有ManyToOne关系都是非可选的或非空的.
All your ManyToOne relationships are either non-optional or not-null.
因此，Hibernate生成INNER JOINS.您必须确保您的数据遵循此规则.
So Hibernate generates INNER JOINS. You have to make sure that your data is following this rules.
如果定义非可选关系或非null关系，则还应该对数据库表中的外键具有NOT NULL约束.
If you define non-optional or not null relationships you should also have a NOT NULL constraint on the foreign key in the database table.
