我試圖建立我自己的模型，並通過initial-data.yml填充它。播放框架2.0 Java - 定義模型錯誤和初始data.yml
那就是：
#Artists
artists:
- !!models.Artist
id: 1
name: orelsan
occupation: chanteur
#Records
records:
- !!models.Record
id: 1
title: Le chant des sirenes
vinylType: La classe
pressInfo: a
style: rap
hits: 11
artist: !!models.Artist
id: 1
而不同的java文件，它描述了模型：Record.java -
@Entity
public class Record extends Model{
@Id
public Long id;
@Required
public String title;
public String vinylType;
public String pressInfo;
public String style;
@ManyToOne
public Artist artist;
public int hits;//Number of time played-consulted
/**
* Generic query helper for entity record with id Long
*/
public static Finder<Long,Record> find = new Finder<Long, Record>(Long.class, Record.class);
}
Artist.java -
@Entity
public class Artist extends Model{
@Id
public Long id;
@Required
public String name;
@Required
public String occupation;
/**
* Generic query helper for entity Computer with id Long
*/
public static Finder<Long,Artist> find = new Finder<Long, Artist>(Long.class, Artist.class);
public String toString(){
return name;
}
}
和運行我的應用程序給我以下例外：

我真的不明白這是從哪裏來的。我基本上基於我的代碼ZenTask示例。雖然它會起作用。
有沒有人有想法？
