列值过滤器

  SingleColumnValueFilter filter = new SingleColumnValueFilter(
                    Bytes.toBytes(HBRunner.DEFAULT_FAMILYNAM), Bytes.toBytes( BatteryGroupICU1Columns.BATTERY_GROUP_NO),
                    CompareFilter.CompareOp.EQUAL,Bytes.toBytes(dto.getBatteryGroupNo()));
filter.setFilterIfMissing(true);

行键过滤

 Filter filter=new RowFilter(CompareFilter.CompareOp.EQUAL,
                    new SubstringComparator(dto.getBatteryGroupNo()+"_"));
scan.setFilter(filter);
