地图<entity1，list <entity2 =“”>＆gt;的Hibernate映射

Question

我不知道如何映射？！在这里，我的课程..如果没有手动填写地图，它甚至可能吗？

public class Configuration {
  @Id
  private long id;
  ??
  private Map<Room, List<Label>> roomLabelMapping;
}

 public class Label {
   @Id
   private long labelId;
   ??
 }

 public class Room {
   @Id
   private String roomMail;
   @ManyToOne
   private Configuration configuration;
 }
