Question

我有这个错误“无法创建sessionFactory object.org.hibernate.MappingException：关联引用未映射的类：事件”，我不知道为什么。谢谢你的帮助这是我的类Event，Event.hbm.xml和hibernate.cfg.xml Event.java

public class Event {

    /** Attributs */

    private int id;     
    private String description;     
    private String hashtag;     
    private Date debut;     
    private Date fin;       
    private Position position;      
    private List<Marqueur> marqueurs;       
    private List<Invitation> invitations;       
    private User proprietaire;      
    private List<User> invites;

    /** 
     * Constructeur 
     * */ 
    public Event()
    {           
    }

    public Event(String description, String hashtag, Date debut, Date fin,
            Position position, User proprietaire) {
        super();
            ...
    }
        // Getters and setters    
}
