我正在尝试使用 JPA 2（使用 Hibernate）与有序多端（使用 List）建立双向关系。

基于以下问题报告的问题@OneToMany(mappedBy：
Hibernate 3.5 中的 JPA 2.0 @OrderColumn 注释
和
https://hibernate.onjira.com/browse/HHH-5732

我尝试了不同的方法，建议在：http:
//josian.wordpress.com/2006/09/09/hibernate-annotations-bidirectional-one-to-many/

但是，在持久化数据时，我遇到了异常。

考虑以下实体类：

@Entity
public class Schedule implements Serializable {
    private List<Presentation> presentations;
    private String name = null;

    ...

    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, orphanRemoval = true)
    @JoinColumn (name = "SCHEDULE_NAME")
    @IndexColumn(name = "PRESENTATION_POSITION")
    public List<Presentation> getPresentations() {
        return presentations;
    }

    @Id
    @NotNull
    @Index(name = "ScheduleNameIdx")
    @Column(name = "SCHEDULE_NAME")
    public String getName() {
        return name;
    }

...
}

@Entity
public class Presentation implements Serializable {
    private Long id;
    private Schedule schedule;

    ...

    @Id
    @GeneratedValue
    @Index(name = "PresentationIdIdx")
    @Column(name = "PRESENTATION_ID")
    public Long getId() {
        return id;
    }

    @ManyToOne(optional = false)
    @JoinColumn(name="SCHEDULE_NAME", nullable = false, updatable = false, insertable = false)
    public Schedule getSchedule() {
        return schedule;
    }
...
}

我得到的例外是：

在您的 Presentation 实体中，将 getSchedule() 的 insertable 和 updateble 属性更改为true。见下文;

   @ManyToOne(optional = false)
   @JoinColumn(name="SCHEDULE_NAME", nullable =false, updatable = true, insertable = true)
   public Schedule getSchedule() {
      return schedule;
   }

对于你的persist策略，hibernate会先将记录插入'Presentation'表，然后更新它的'schedule_id'，但是你设置schedule_id不为null，所以插入会失败。

一种解决方案是删除“非空”约束。</p>

第二种方案是重新设计关系配置，让hibernate只执行一个插入语句（包括'schedule_id'），不需要更新

删除@NotNull。非关键字段不允许空值。考虑输入数据。

为什么要updatable = false, insertable = false在PresentationtoSchedule映射中指定？

当然，这个值需要是可插入和可更新的以维持关系。尝试删除它，您应该在尝试插入时看到 SQL 更改。
