这一行报错

 QueryResult qr = new QueryResult();
        qr.setList(dao.query(DfjgQuotaAllotDO.class,cnd,pager));
    @Column("BSHX0043")
    private Number quotaNum;


    public Number getQuotaNum() {
        return quotaNum;
    }

    public void setQuotaNum(Number quotaNum) {
        this.quotaNum = quotaNum;
    }
