如题：假如我有个对象Course，Course有个一对一的关联对象Media，Media有个一对一的关联对象Teacher，现在我要查Course分页列表，有什么好的办法直接查出关联对象？
course对象：

@Column("media_id")
    @ColDefine(type = ColType.INT  ,width = 11   ,notNull =  false  )
    @Comment("媒体资源ID")
    private int mediaId;

    @One(field = "mediaId")
    private Media media;

media对象：

 @Column("teacher_id")
    @ColDefine(type = ColType.INT  ,width = 10   ,notNull =  true )
    @Comment("")
    private int teacherId;

    @One(field = "teacherId")
    private Teacher teacher;
