java - ORMLite 外部字段类没有 id 字段

Question

我在有关此问题的其他问题上看到了同样的错误。正如你所看到的，我似乎没有什么问题!除非我的眼睛欺骗了我。有什么帮助吗？

这是我的两个模型:

public class Outer {

    @DatabaseField(id = true, canBeNull = false, columnName = "id")
    private int id;

    @DatabaseField
    private long parentOuterId;

    @ForeignCollectionField(eager = false)
    private ForeignCollection<Item> items;
    //getters and setters
}


public class Item {

    @DatabaseField(canBeNull = false, columnName = "id")
    private int id;

    @DatabaseField(canBeNull = false, foreign = true, foreignAutoRefresh = true)
    private Outer out;

    //getters and setters
}

Answer 1

您忘记将 id = true 或 generatedId = true 添加到 @DatabaseField 注释中:

@DatabaseField(id = true, canBeNull = false, columnName = "id")
private int id;
