HyperLoglog弹簧键操作

Question

我有下面的代码片段来测试是否可以在Redis中添加HLL值，这个测试通过，但是当我从redis命令行验证它时，我没有看到"HLLTEST“键，而是发现了奇怪的键，正如您可以从下面的输出中看到的那样。HyperLogLogOperations的使用有什么问题吗，

@Test
    public void whenHllRecord_thenCount() throws Exception {
        hyperLogLogOperations = redisTemplate.opsForHyperLogLog();

        hyperLogLogOperations.add("HLLTEST:1010", 1);
        hyperLogLogOperations.add("HLLTEST:1010",2);

        long size = hyperLogLogOperations.size("HLLTEST:1010");

        assertEquals("Size: "+size, size, 2);
    }

Redis-Command-Line

redis:6379> keys *
 1) "\xac\xed\x00\x05t\x00\x0cHLLTEST:1010"
redis:6379> pfcount HLLTEST:1010
(integer) 0

RedisConf

 @Bean
   public RedisTemplate<String, Object> redisTemplate() {
      final RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
      template.setConnectionFactory(jedisConnectionFactory());
      template.setValueSerializer(new GenericToStringSerializer<Object>(Object.class));
      return template;
   }

我忘了放钥匙串行器了。将其设置为下列工作方式之后，

  @Bean
   public RedisTemplate<String, Object> redisTemplate() {
      final RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
      template.setConnectionFactory(jedisConnectionFactory());

     //template.setValueSerializer(new GenericToStringSerializer<Object>(Object.class));

      template.setKeySerializer(new StringRedisSerializer());
      template.setValueSerializer(new StringRedisSerializer());

      return template;
   }
