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：序列号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进行序列号然后用不对称的反序列化方法C进行反序列号 ， 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));
