Can not set java.lang.Integer field com.persistence.entity.CustomerOrderEntity.tenantId to java.lang.String

Question

每當我從 CustomerOrderEntity 中刪除一對一關系時，我的下一個示例就會出現問題，我的測試通過沒有問題但是當我放回關系時，它失敗告訴我不能將字符串分配給 Integer 怎么辦我的代碼有問題嗎？ 我該如何解決？

    private CustomerOrderEntity order;
}

與下一個 spring 引導存儲庫

@Repository
public interface CustomerOrderEntityRepository extends JpaRepository<CustomerOrderEntity, String>, JpaSpecificationExecutor<CustomerOrderEntity> {

    @EntityGraph(CustomerOrderEntity.GRAPH_WITH_LINES)
    @Query("select entity from CustomerOrderEntity entity where entity.tenantId = :#{#param.tenantId} and entity.fulfilLocationId = :#{#param.fulfilLocationId} and entity.fulfilOrderId = :#{#param.fulfilOrderId}")
    Optional<CustomerOrderEntity> findOneByOrderIdWithLines(CustomerOrderEntity param);

    @EntityGraph(CustomerOrderEntity.GRAPH_WITH_DELIVERY)
    @Query("select entity from CustomerOrderEntity entity where entity.tenantId = :#{#param.tenantId} and entity.fulfilLocationId = :#{#param.fulfilLocationId} and entity.fulfilOrderId = :#{#param.fulfilOrderId}")
    Optional<CustomerOrderEntity> findOneByOrderIdWithDelivery(CustomerOrderEntity param);

    @EntityGraph(CustomerOrderEntity.GRAPH_WITH_ALL_PROPS)
    @Query("select entity from CustomerOrderEntity entity where entity.tenantId = :#{#param.tenantId} and entity.fulfilLocationId = :#{#param.fulfilLocationId} and entity.fulfilOrderId = :#{#param.fulfilOrderId}")
    Optional<CustomerOrderEntity> findOneByOrderIdWithAllProps(CustomerOrderEntity param);

}

和下一個測試：

當我嘗試從存儲庫中檢索 CustomerOrderEntity 時，它會給出下一個錯誤跟蹤：

我認為您需要為域對象的屬性添加 getter 和 setter。 您可以首先為 CustomerOrderEntity.tenantId 添加一個 getter 和一個 setter，以查看在您嘗試重現此問題時是否會改變行為。
