在 java ，

try (HTable table = new HTable(new JobConf(HBaseConfiguration.create()), TABLE_NAME)) {
        byte[][] keys = table.getStartKeys();
        for (byte[] keyBytes : keys) {
            String key = new String(keyBytes, StandardCharsets.UTF_8);
            // first region does not have start key (is null)
            // last region does not have end key
            if (StringUtils.isNotBlank(key)) {
                System.out.println(key);
            }
        }
    }
