我看到您当前的型号：

房间---有许多--->房间设施

如果这是真的，根据使用

OnetoMany

@Entity
@Table(name = "room")
public class Room implements Serializable {
    //... some code previous

    @OneToMany
    @JoinColumn(name = "facility_id") //enough to use the @JoinColumn annotation
    private Set<Facility> facilities;

    //... more code after
}

@实体
@表（name=“房间”）
公共教室实现了可序列化{
//…以前的一些代码
@独身癖
@JoinColumn（name=“facility\u id”）//足以使用@JoinColumn注释
私人设施；
//…后面还有更多代码
}

注释

@JoinTable

更多地用于反映多对多关系

我检查了您的映射-它是正确的

Hibernate创建一个连接表

room\u facility

，将room连接到facility

 create table room_facility (
        facility_id bigint not null,
        room_id bigint not null,
        primary key (facility_id, room_id)
    )

并向表中添加三个约束

alter table room_facility 
        add constraint UK_7agxlay88uohhk0oiulxd8o2f unique (room_id)

alter table room_facility 
    add constraint F_room_facility_room_id 
    foreign key (room_id) 
    references facility

alter table room_facility 
    add constraint F_room_facility_facility_id 
    foreign key (facility_id) 
    references room

约束是正确的，但名称混乱。原因-指定的联接列名不正确

你应该改变这个

@JoinTable(name = "room_facility", joinColumns = @JoinColumn(name = "facility_id"),
        inverseJoinColumns = @JoinColumn(name = "room_id"))

对此

@JoinTable(name = "room_facility", joinColumns = @JoinColumn(name = "room_id"),
        inverseJoinColumns = @JoinColumn(name = "facility_id"))

因此，将使用正确名称的约束

alter table room_facility 
    add constraint UK_ps5vy16iklc6x2w1etbbt98q7 unique (facility_id)

alter table room_facility 
    add constraint FKj7d5o0yjvyvev7owenan66mcy 
    foreign key (facility_id) 
    references facility

alter table room_facility 
    add constraint FKt8cyiqxlu6kpr29sa7n1vk4pm 
    foreign key (room_id) 
    references room

错误原因

如我们所见，我们对联接表

room\u facility

的

facility\u id

列有一个唯一的约束。所以我们不能有两间有相同设施的房间

如果您需要为多个房间使用相同的设备，您可以尝试使用

@manytomy
