使用FilterList要保证过滤器的顺序需要使用List<Filter>

 private static void mutilFilterData() throws IOException{
        Table table = helper.getConnection().getTable(TableName.valueOf("testtable"));

        List<Filter> filters = new ArrayList<Filter>();

        Filter filter1 = new RowFilter(CompareOperator.GREATER_OR_EQUAL,
                new BinaryComparator(Bytes.toBytes("rowKey60")));
        filters.add(filter1);

        Filter filter2 = new RowFilter(CompareOperator.LESS_OR_EQUAL,
                new BinaryComparator(Bytes.toBytes("rowKey69")));
        filters.add(filter2);

        Filter filter3 = new QualifierFilter(CompareOperator.EQUAL,
                new RegexStringComparator("username"));
        filters.add(filter3);

        FilterList filterList1 = new FilterList(FilterList.Operator.MUST_PASS_ALL,filters);

        Scan scan = new Scan();
        scan.setFilter(filterList1);
        ResultScanner scanner1 = table.getScanner(scan);
        System.out.println("Results of scan #1 - MUST_PASS_ALL:");
        int n = 0;
        for (Result result : scanner1) {
            for (Cell cell : result.rawCells()) {
                System.out.println("Cell: " + cell + ", Value: " +
                        Bytes.toString(cell.getValueArray(), cell.getValueOffset(),
                                cell.getValueLength()));
                n++;
            }
        }
        scanner1.close();
        table.close();

    }

输出结果:

Cell: rowKey60/info:username/1555078771906/Put/vlen=6/seqid=0, Value: user60
Cell: rowKey61/info:username/1555078771906/Put/vlen=6/seqid=0, Value: user61
