其中 approverecord 是 多个 数据

我这么写也能解决 我需要的问题 但是总感觉不对

 @Override
    public T_approvalProcess queryById(String q_id) {
        StringBuffer str = new StringBuffer("SELECT  ap.*,ar.* FROM t_approvalProcess AS ap JOIN t_approverecord AS ar ON ap.approvalRecordId = ar.alp_id JOIN t_leave AS l ON l.approvalProcessId = ap.ap_id WHERE  l.q_id = @q_id ");
        Sql sql = Sqls.queryRecord(str.toString());
        sql.params().set("q_id",q_id);
        dao.execute(sql);
        List<Record> records = sql.getList(Record.class);
        T_approvalProcess approvalProcess = new T_approvalProcess();
        List<T_approverecord> list  = new ArrayList<T_approverecord>();
        for(Record r : records){
            approvalProcess = r.toEntity(dao.getEntity(T_approvalProcess.class));
            T_approverecord approverecord = r.toEntity(dao.getEntity(T_approverecord.class));
            list.add(approverecord);
        }
        approvalProcess.setApproverecords(list);
        return approvalProcess;
    }
