我想从CRUDRepository中得到一些东西，比如(werkstattId是一个字符串):

appointment.dealerid = dealerRepository.findByIdOrNull(werkstattId)

经销商类：

@Entity
@Table(name = "dealer", schema = "app-db")
open class Dealer {
    @Id
    @Column(name = "dealerid", nullable = false, length = 10)
    open var id: String? = null

    @Column(name = "name", length = 30)
    open var name: String? = null

    @Column(name = "max_parallel_appointments")
    open var maxParallelAppointments: Int? = null
}

回购看起来像这样

interface DealerRepository : CrudRepository<Dealer, String> {
}

并连接到PostgreSQL数据库，表如下所示

CREATE TABLE IF NOT EXISTS dealer (
    dealerId varchar(10) NOT NULL PRIMARY KEY,
    name varchar(30),
    max_parallel_appointments smallint
);

表中有两个条目，但尽管如此，当我运行findByIdOrNull函数时，我还是得到了下面的异常:
