您可以使用columnprefixfilter。您可以看到以下代码

Configuration hadoopConf = new Configuration();
    hadoopConf.set("hbase.zookeeper.quorum", "localhost");
    hadoopConf.set("hbase.zookeeper.property.clientPort", "2181");

    HTable hTable = new HTable(hadoopConf, "KunderaExamples");

    Scan scan = new Scan();
    scan.setFilter(new ColumnPrefixFilter("A".getBytes()));
    ResultScanner scanner = hTable.getScanner(scan);
    Iterator<Result> resultsIter = scanner.iterator();
    while (resultsIter.hasNext())
    {

        Result result = resultsIter.next();

        List<KeyValue> values = result.list();
        for (KeyValue value : values)
        {
            System.out.println(value.getKey());
            System.out.println(new String(value.getQualifier()));
            System.out.println(value.getValue());
        }
    }
