如何为具有ForeignCollection的类创建DataTableConfig？

Question

我希望通过 ormlite 4.48 保留两个遗留类。 这些课程无法修改，因此我无法使用优秀的注释。

幸运的是，DatabaseTableConfig来救援。

这是我的课程：

public class RedditLink extends RedditType {

    // Thing
    private String id;
    private String name;
    private String kind;
    private String data;

    // Votable
    private int ups;
    private int downs;
    // Uncomment if this ever matters private boolean likes;

    // Created
    private long created_utc;

    // Link
    private String author;
    private String domain;
    private int num_comments;
    private boolean over18;
    private boolean is_self;
    private String permalink;
    private String subreddit;
    private String subredditId;
    private String title;
    private String url;
    private String selftext;

    private String thumbnail;

    private RedditLinkList list;

       ... Getters and setters
}

和

public class RedditLinkList {

    private int id;

    public static final RedditLinkList EMPTY = new RedditLinkList();

    public Collection<RedditLink> links = new ArrayList<RedditLink>();

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public Collection<RedditLink> getLinks() {
        return links;
    }

    public void setLinks(Collection<RedditLink> links) {
        this.links = links;
    }
}

我收到以下错误

以下是我用来生成DatabaseFieldConfig的代码：

        //
        // Link
        //
        List<DatabaseFieldConfig> fieldConfigs = new ArrayList<DatabaseFieldConfig>();
        DatabaseFieldConfig field1 = new DatabaseFieldConfig("id");
        field1.setId(true);
        fieldConfigs.add(field1);

        DatabaseFieldConfig field2 = new DatabaseFieldConfig("name");
        field2.setCanBeNull(false);
        fieldConfigs.add(field2);

        DatabaseFieldConfig field3 = new DatabaseFieldConfig("url");
        fieldConfigs.add(field3);

        DatabaseFieldConfig field4 = new DatabaseFieldConfig("title");
        fieldConfigs.add(field4);

        DatabaseFieldConfig field6 = new DatabaseFieldConfig("author");
        fieldConfigs.add(field6);

        DatabaseFieldConfig field5 = new DatabaseFieldConfig("subreddit");
        fieldConfigs.add(field5);

        // @DatabaseField(foreign = true, foreignAutoRefresh = true,
        // canBeNull =
        // true, columnName = "list_id")
        DatabaseFieldConfig field7 = new DatabaseFieldConfig("list");
        field7.setForeign(true);
        field7.setForeignAutoRefresh(true);
        field7.setCanBeNull(true);
        field7.setColumnName("list_id");

        fieldConfigs.add(field7);

        DatabaseTableConfig<RedditLink> link = new DatabaseTableConfig<RedditLink>(
                RedditLink.class, fieldConfigs);

        //
        // List
        //
        List<DatabaseFieldConfig> fieldListConfigs = new ArrayList<DatabaseFieldConfig>();
        DatabaseFieldConfig fieldList1;

        fieldList1 = new DatabaseFieldConfig("id");
        fieldList1.setColumnName("list_id");
        fieldList1.setGeneratedId(true);
        fieldListConfigs.add(fieldList1);

        DatabaseFieldConfig fieldList2 = new DatabaseFieldConfig("links");
        fieldList2.setForeignCollection(true);
        fieldList2.setForeignCollectionEager(false);
        fieldListConfigs.add(fieldList2);

        DatabaseTableConfig<RedditLinkList> list = new DatabaseTableConfig<RedditLinkList>(
                RedditLinkList.class, fieldListConfigs);
        // Cross references
        field7.setForeignTableConfig(list);
        fieldList2.setForeignTableConfig(link);

我做错了什么？

注意：我的应用使用ormlite_config.txt缓存
