dao 可以在查询出来的字段去掉空格吗？

查询出来的字段会显示有这样（老数据库- -）

{"code":"1","msg":"stm.success","obj":[{"sp":"潮盛 橄榄菜450g","gg":"1*12","dw":"瓶        ","lsj":12.9000}, {"sp":"潮盛 橄榄菜170g","gg":"1*12","dw":"瓶        ","lsj":6.0000}, {"sp":"潮盛 橄榄菜（碟装）112g","gg":"1*72","dw":"碟        ","lsj":3.0000}, {"sp":"糯米","gg":"","dw":"kg        ","lsj":5.8000}, {"sp":"散装山水月芽米","gg":"","dw":"KG        ","lsj":4.3800}]}

查询语句是这样

  @At("/goodsList")
    @Ok("json")
    public Result  getGoodsList(@Param("token")String token,@Param("type")String type,
                                @Param("page")int page,@Param("pageSize")int pageSize){
        List<Goods> list = null;
        try {
            Dao dao = managerServer.getBusiness(token);
            Pager pager = PagerUtil.conPager(page, pageSize);
            Cnd cnd = Cnd.NEW();
            if(Strings.isNotBlank(type))cnd.and("kindcode","=",type); // 小分类
            cnd.desc("zjt").desc("djdate");
            list = dao.query(Goods.class, cnd, pager, "^(sp|gg|dw|lsj)$"); // 这里只取零售价
        } catch (BizException e1) {
           return ExceptionBulider.handleException(e1);
        } catch (Exception e) {
            return Result.error();
        }
        return Result.success(list);
    }

有没有dao实现对查询出来的字段把空格去掉不确定哪些参数会有这种空格的啊！！
