java - Hibernate 标准 - org.hibernate.QueryException : could not resolve property:

Question

我的模型类中有 setter 和 getter，但仍然出现异常。这是我的模型类。

    @Entity
    @Table(name="A_CPView")
    public class APRecord extends AbstractAPRecord implements ARecord {
      private AMaID mAiD;

        private String aId = null;
        @Transient
        public String getAId() {
        if (getMAiD() != null) {
        if (getMAiD().getId() != null) {
            aId = getMAiD().getId().toString();
        }
    }

    return aId;
}

public void setAId(String aId) {
    this.aId = aId;
}
 @ManyToOne
@JoinColumn(name="agentG")
public AMaID getMAiD() {
    return mAiD;
}

public void setMAiD(AMaID mAiD) {
    this.mAiD = mAiD;
}
}

在我的 DAO 中:

     Criteria crit = statelessSession.createCriteria(APRecord.class, "accmpr");
    crit.createAlias("AMaID", "aMaId", Criteria.INNER_JOIN);


    crit.addOrder( Order.asc("pName") );
    crit.addOrder( Order.asc("kNum") );
    crit.setProjection(Projections.distinct(Projections.property("aId")));
    return crit.scroll(ScrollMode.FORWARD_ONLY);

它给了我一个:

org.hibernate.QueryException: could not resolve property: aId

谁能告诉我错误是什么？

这与将 aId getter 设置为 Transient 有关吗？ Hibernate 不会获取/设置 Transient 属性的值，因为它不应该如此。
