org.hibernate.QueryException：无法解析属性：类似于：hibernetMappings.PostMessages

Question

如何解决

org.hibernate.QueryException: could not resolve property: likeses of:  
hibernetMappings.PostMessages  

PostMessages.java

public class PostMessages  implements java.io.Serializable {
        private Long messageid;
         private String message;
         private String visibility;
         private String messageType;
         private Set likeses = new HashSet(0);
     //getter setter and constructors
    }

Likes.java

public class Likes  implements java.io.Serializable {

     private LikesId id;
     private Atom atom;
     private PostMessages postMessages;
     private Date adddate;
     private String status;
     private Date deleteTime;
    //getter setter and constructors
}

LikesId.java

public class LikesId  implements java.io.Serializable {
     private long messageid;
     private int aid;
//getter setter and constructors
}

Likes.hbm.xml

我正在尝试关注hql

from PostMessages as pm
left join fetch pm.likeses as likes
where likes.id.messageid=67
and likes.id.aid=1

哪个显示错误
