java - 如何在其他实体中映射同一列两次

标签 java hibernate jpa

我是新使用 hibernate 来映射实体，我试图在两个不同变量中为我的一个实体使用同一列，让我解释一下，我有一个名为“匹配”的实体，该实体将包含有关比赛的信息，包括本地球队和客场球队。

另一个实体是团队，一场比赛有两个不同的团队，团队可以与其他团队进行多场比赛。

当我尝试检索所有匹配项时，出现异常

我正在使用 SpringBoot 2.1.7、Java 8 和 Hibernate 5


@Entity(name = "matches")
public class Matches {

    //Attributes
    @Id
    @Column(name = "id", unique = true, nullable = false)
    private Long id;

    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "local_team_id", referencedColumnName = "id")
    private Team localTeam;

    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "away_team_id", referencedColumnName = "id")
    private Team awayTeam;


@Entity(name = "teams")
public class Team {

    //Attributes
    @Id
    @Column(name = "id", unique = true, updatable = false, nullable = false)
    private Long id;


    @OneToOne(mappedBy = "localTeam")
    private Matches localMatches;

    @OneToOne(mappedBy = "awayTeam")
    private Matches awayMatches;

当我尝试加载所有比赛时，我得到了这个，我可以弄清楚我是如何声明比赛与团队之间的关联的，但我仍然对应该如何声明它感到困惑。

最佳答案

我认为您与 local/awayTeam -> matches 存在 @oneToMany 连接，因为 一个团队还可以参加多场比赛。

|Team A | matches | team B |

| 1 | a | 2 |

| 1 | b | 3 |

| 1 | c | 4 |

| 1 | d | 5 |

等等

@OneToMany(mappedBy = "localTeam")
private Iterable<Matches> localMatches;

@OneToMany(mappedBy = "awayTeam")
private Iterable<Matches> awayMatches;
