不解释，看代码去吧，很简单。

 private long findBatterHisDataCount(BatteryHisDto dto) throws Exception{
        long totalSize=0;
        Table table=runner.getTable(tableName);
        Scan countScan = new Scan();
        ResultScanner countScanner = null;
        List<Filter> countFilters = new ArrayList<Filter>();
        if(StringUtils.isNotBlank(dto.getBatteryNo())){//电池组编号过滤
            Filter filter=new RowFilter(CompareFilter.CompareOp.EQUAL, new SubstringComparator(dto.getBatteryNo()+"_"));
            countFilters.add(filter);
        }
        countFilters.add(new FirstKeyOnlyFilter());
        FilterList countFilterList = new FilterList(FilterList.Operator.MUST_PASS_ALL, countFilters);
        countScan.setFilter(countFilterList);
        countScan.setCaching(500);
        countScan.setCacheBlocks(false);
        countScanner = table.getScanner(countScan);
        for (Result result : countScanner) {
            totalSize ++;
        }
        return totalSize;
    }
