hbase按照时间倒序查询话费清单手机号码:时间戳:对方号码,给出代码

以下是Java代码示例：

Configuration config = HBaseConfiguration.create();
Connection connection = ConnectionFactory.createConnection(config);

String tableName = "call_records";
Table table = connection.getTable(TableName.valueOf(tableName));

Scan scan = new Scan();
scan.setReversed(true); // 按时间倒序查询
FilterList filters = new FilterList(FilterList.Operator.MUST_PASS_ALL);

// 构造手机号码反转过滤器
SingleColumnValueFilter reverseFilter = new SingleColumnValueFilter(Bytes.toBytes("cf"), Bytes.toBytes("phone_number"),
        CompareOperator.NOT_EQUAL, new BinaryComparator(Bytes.toBytes("")));
ReverseStringComparator reverseComparator = new ReverseStringComparator();
reverseFilter.setComparator(reverseComparator);
filters.addFilter(reverseFilter);

// 构造时间戳过滤器
SingleColumnValueFilter timestampFilter = new SingleColumnValueFilter(Bytes.toBytes("cf"), Bytes.toBytes("timestamp"),
        CompareOperator.NOT_EQUAL, new BinaryComparator(Bytes.toBytes("")));
filters.addFilter(timestampFilter);

scan.setFilter(filters);

ResultScanner scanner = table.getScanner(scan);
for (Result result : scanner) {
    String phoneNumber = new StringBuilder(Bytes.toString(result.getValue(Bytes.toBytes("cf"), Bytes.toBytes("phone_number")))).reverse().toString();
    String timestamp = Bytes.toString(result.getValue(Bytes.toBytes("cf"), Bytes.toBytes("timestamp")));
    String otherPhoneNumber = Bytes.toString(result.getValue(Bytes.toBytes("cf"), Bytes.toBytes("other_phone_number")));
    System.out.println("Phone number: " + phoneNumber + ", timestamp: " + timestamp + ", other phone number: " + otherPhoneNumber);
}

scanner.close();
table.close();
connection.close();

假设表结构如下：

RowKey: 13912345678_20220101120000
Column Family: cf
Column: phone_number, timestamp, other_phone_number
Value: 13912345678, 20220101120000, 15812345678

其中 RowKey 由手机号码和时间戳组成，手机号码需要反转。上述代码会按照时间倒序查询所有行，并且过滤掉手机号码、时间戳或对方号码为空的行。查询结果会输出每行的反转后的手机号码、时间戳和对方号码。
