redisTemplate 封装bitcout

@Repository
public class RedisServiceExtend {
    @Autowired
    private RedisTemplate<String, String> redisTemplate;

    private static String redisCode = "utf-8";

    public long bitCount(final String key) {
        return redisTemplate.exec((RedisCallback<Long>) con -> con.bitCount(key.getBytes()));
    }

    public Long bitCount(String key, int start, int end) {
        return redisTemplate.execute((RedisCallback<Long>) con -> con.bitCount(key.getBytes(), start, end));
    }

    public Long bitOp(RedisStringCommands.BitOperation op, String saveKey, String... desKey) {
        byte[][] bytes = new byte[desKey.length][];
        for (int i = 0; i < desKey.length; i++) {
            bytes[i] = desKey[i].getBytes();
        }
        return redisTemplate.execute((RedisCallback<Long>) con -> con.bitOp(op, saveKey.getBytes(), bytes));
    }
