在java hibernate中，父id不插入到子表中

Question

    @OneToMany(mappedBy = "serviceConfig", fetch = FetchType.EAGER, cascade = CascadeType.ALL, orphanRemoval = true)
    private List<NotificationItem> notificationItems;

    @OneToMany(mappedBy = "serviceConfig", fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
    private List<QosItem> qosItems;

    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "TD_SERVICE_CONFIG_ID")
    private ServiceConfig serviceConfig;

Answer 1

你的配置看起来不错。

我怀疑（尽管在没有看到您的代码的情况下显然无法确定）您没有设置关系的反向面，这是必需的。您将添加notificationitem，如下所示：

NotificationItem item = new NotificationItem();
item.setServiceConfig(service);  //set the other side of the bi-directional relationship
servive.getNotificationItems().add(item);

中线是这里重要的一条。
