在ormlite中，我如何拥有前字段和字段列？

Question

我的实体就是这样。

@Data
public class Comment implements Persistable<Long>, CBHistoryTable
{
    @Id
    private Long tid;
    // sid and pid is required for serialized to json
    @DatabaseField
    private Long pid;
    @DatabaseField
    private Long sid;

    @DatabaseField(foreign = true, foreignColumnName = "sid", columnName = "sid")
    private Article article;

    @DatabaseField(foreign = true, foreignColumnName = "pid", columnName = "tid")
    private Comment parent;
}

当我插入时，将导致SQL语法异常， Column 'sid' specified twice 。 在ormlite表配置中， sid和article都被视为具有相同名称的列。

我该如何实现？

这是我的文章实体

@Data
@DatabaseTable(daoClass = ArticleServiceImpl.class)
public class Article implements Persistable<Long>, CBHistoryTable
{
    @Id
    @SerializedName("SID")
    private Long sid;

    @SerializedName("SN")
    @DatabaseField
    private String sn;

    @ForeignCollectionField(foreignFieldName = "article")
    private Collection<Comment> comments = Sets.newHashSet();
}

您更改了问题，所以最后一个答案不再起作用，请尝试一下并告诉我是否是您要的内容：

@Data
public class Comment implements Persistable<Long>, CBHistoryTable
{
    @Id
    private Long tid;
    // sid and pid is required for serialized to json
    private Long pid;
    private Long sid;

    @DatabaseField(canbenull = true, foreign = true, foreignColumnName = "sid")
    private Article article;

    @DatabaseField(canbenull = true, foreign = true, foreignColumnName = "tid")
    private Comment parent;

    @ForeignCollectionField(foreignFieldName = "parent")
    private Collection<Comment> comments = Sets.newHashSet();

    public void setArticle(Article article) {
        this.article = article;
        sid=article.getSid();
    }

    public void setParent(Comment parent) {
        this.parent = parent;
        pid=comment.getTid();
    }
}

@Data
@DatabaseTable(daoClass = ArticleServiceImpl.class)
public class Article implements Persistable<Long>, CBHistoryTable
{
    @Id
    @SerializedName("SID")
    private Long sid;

    @SerializedName("SN")
    private String sn;

    @ForeignCollectionField(foreignFieldName = "article")
    private Collection<Comment> comments = Sets.newHashSet();
}
