RedisTemplate SerializationFailedException: Failed to deserialize payload 异常解决

问题描述：

   使用RedisTemplate(spring-data-redis )进行redis操作的封装 ， 现有一个incr的key , 当调用incr后返回值一切正常， 当对此key进行get调用的时候出现了如下的异常：

org.springframework.data.redis.serializer.SerializationException: Cannot deserialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to deserialize payload.

以看出是sping对redis查询的返回结果进行deserialize的时候出错了 ， 当然异常的提示也很明确：***对象生成这个字节数组的方法是否与默认的反序列化方法相对应；应该就是对称性吧 ， 你用A方法对B进行***然后用不对称的反序列化方法C进行反*** ， 肯定会有问题 ， 结果在国外大神的回复中找到了答案：

        提简单来说调用incr后得到 值不会出错是没有经过redistemplate的deserialize, 而get必须经过 ， 所以只要设置redistemplate的ValueSerializer即可：

redisTemplate.setValueSerializer(new GenericToStringSerializer<Long>(Long.class));
