Spring OneToMany双向映射，缺少列

我想不出是什么问题。由于某种原因，Hibernate正在抛出关于“总线表中缺少route_id列”的错误。如果我创建列并让它为空，那么一切都可以按我所希望的方式工作。为什么它需要它？我不需要它。也许有人能帮我，提前谢谢

@Entity
@Getter
@Setter
@Table(name = "bus")
public class Bus {
    @Id
    @Column(name = "bus_id", columnDefinition = "VARCHAR(36)")
    private String id = UUID.randomUUID().toString();

    @NotBlank
    @Length(min = 4, max = 15)
    private String name;

    @OneToMany(mappedBy = "bus", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    private Set<Route> routes;
}

您的

路线

实体上有过多的

@SecondaryTable（name=“bus”）

同时，您与总线有@manytone关系：

@ManyToOne
@JoinColumn(name = "bus_id", referencedColumnName = "bus_id")
private Bus bus;

这告诉我，辅助表毫无意义——它仅用于一个实体在两个表之间拆分的情况（例如：主表和明细表）。这里有两个实体

这句话同样适用于

@SecondaryTable（name=“location”）

-您需要删除此注释

有关正确使用@SecondaryTable的更多信息，请参阅

@Entity
@Getter
@Setter
@Table(name = "route")
@SecondaryTables({
        @SecondaryTable(name = "location"),
        @SecondaryTable(name = "bus")
})
public class Route {
    @Id
    @Column(name = "route_id", columnDefinition = "VARCHAR(36)")
    private String id = UUID.randomUUID().toString();

    private int leaving;
    private int arrival;
    @Column(columnDefinition = "DECIMAL", precision = 4, scale = 2)
    private BigDecimal price;

    @ManyToOne
    @JoinColumn(name = "bus_id", referencedColumnName = "bus_id")
    private Bus bus;

    @ManyToOne
    @JoinColumn(name = "route_to", referencedColumnName = "name")
    private Location routeTo;

    @ManyToOne
    @JoinColumn(name = "route_from", referencedColumnName = "name")
    private Location routeFrom;
}
