就是要写成这样的吗？

Cnd.wrap("name LIKE 'J%' AND age>20")

用这个Criteria cri = Cnd.cri(); 怎么完成查询列表的这个操作

 public Object data(String wxid, @Param("nickname") String nickname,
    		@Param("startDate") String startDate, @Param("endDate") String endDate,
    		@Param("length") int length, @Param("start") int start, @Param("draw") int draw, 
    		@Param("::order") List<DataTableOrder> order, @Param("::columns") List<DataTableColumn> columns) {
        Cnd cnd = Cnd.NEW();
        Criteria cri = Cnd.cri();
        if (!Strings.isBlank(wxid)) {
        	cri.where().and("wxid", "=", wxid);
        }
        if (!Strings.isBlank(nickname)) {
        	cri.where().and("nickname", "like", "%" + nickname + "%");
        }
        if(!StringUtils.isBlank(startDate) && !StringUtils.isBlank(endDate)) {
        	//String Str=" and subscribeAt between"+" '"+startDate+"' AND '"+endDate+"'";
        	cri.where().andBetween("subscribeAt", startDate, endDate);
		}
        return wxUserService.data(length, start, draw, order, columns, cri, null);
    }
