Hibernate：OneToMany 關系中的 PSQLException

Question

我有 SpringBoot 應用程序，其中有一個帶有電影院列表的 postgres 數據庫：

cinemadb=# select * from cinemas;
 id |           name            
----+---------------------------
  1 | London''s Electric Cinema
  2 | Alamo Drafthouse
  3 | Cineteca Matadero
  4 | Cine-de Chef
  5 | Castro Theatre
  6 | Cine Thisio

每個電影院都顯示一部電影或多部電影（位於另一個數據庫中）。 我創建了一個關系表：

cinemadb=# select * from cinema_movie;
 cinema_id | movie_id 
-----------+----------
         1 |        1
         1 |        5
         1 |        8
         2 |        2
         3 |        3
         3 |        9
         4 |        1
         4 |        2
         4 |        8
         4 |        9
         6 |        9
         7 |        9
         7 |        1
         8 |        1

在最后一張表中，cinema_id 是鏈接到cinemas 表中的id 的外鍵。 movie_id 只是一個 integer 代表另一個數據庫中的 id。

我的實體表示：

@Entity
@Table(name = "cinemas")
data class Cinema(
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        val id: Long = -1,
        val name: String = "",
        @OneToMany(mappedBy = "cinema", cascade = [CascadeType.ALL])
        @JsonIgnore
        val movies: Set<CinemaMovies> = HashSet()) {

    override fun toString(): String {
        return "Cinema[id=$id, name=$name]"
    }
}

@Entity
@Table(name = "cinema_movie")
data class CinemaMovies(
        @Id
        @ManyToOne
        @JoinColumn(name="cinema_id", nullable=false)
        val cinema: Cinema? = null,
        @Id
        @Column(name = "movie_id")
        val movieId: Long = -1): Serializable

當我嘗試觀看屬於單個電影院的電影時，問題就來了：

我究竟做錯了什么？

Answer 1

這似乎是ManyToMany關系而不是OneToMany關系。 同樣，在單個實體類中，不能使用@Id注釋兩個實例變量。 您必須使用創建ManyToMany關系。
參考示例： https : //www.baeldung.com/hibernate-many-to-many

Answer 2

為電影和電影創建單獨的表並使用 @JoinTable 而不是 @JoinColumn

@JoinTable(
  name = "cinema_movie",
  joinColumns = @JoinColumn(name = "cinema_id"),
  inverseJoinColumns = @JoinColumn(name = "movie_id")
)
