Java JPA OneToMany Manytone

我拥有以下实体：

@Entity
@Table(name="NOTE")
public class Note implements Serializable {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private long id;

    @Column(name="DATE")
    private Calendar date;

    @Column(name="TOTAL")
    private double total;

    @ManyToOne
    private Collaborateur collaborateur;

    @OneToMany(cascade=CascadeType.ALL)
    private List<Frais> listfrais = new ArrayList<Frais>();

    // getters and setters
}

错误是：

Collabour上缺少您的级联首选项。你的代码里有这个

@ManyToOne(cascade =CascadeType.ALL)
private Collaborateur collaborateur;

---

在此处添加级联类型。

您想告诉我们您具体要求什么吗？您可以在Collabour上添加级联，或执行循环，然后逐个保存每个元素，然后在Collabour上保存。谢谢，但在将级联添加到ManyTone后，我出现了新错误。我将其发布在topdetached entity错误中，表示您的交易不起作用。检查您是否将票据保存在提取票据的同一事务中。还要确保私有协作器上的级联类型正确；我不知道我有什么要改变你，我张贴了你能看到的所有课程，告诉我问题是什么，谢谢你的回答。 déc. 04, 2014 4:37:09 PM org.jboss.ejb.client.remoting.ChannelAssociation resultReady INFO:
