RedisTemplate SerializationFailedException: Failed to deserialize payload 异常解决_attempt to deserialize unauthorized class

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. Is the byte array a result of corresponding serialization for DefaultDeserializer?; nested exception is java.io.EOFException

        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));

补充说明： 经过几天的学习发现这个异常只需要配置RedisTemplate的几个属性就可以了：

	
                <property name="keySerializer">
			<bean
				class="org.springframework.data.redis.serializer.StringRedisSerializer" />
		</property>
		<property name="valueSerializer">
			<bean
				class="org.springframework.data.redis.serializer.StringRedisSerializer" />
		</property>



这样不仅可以解决redis中key前面奇葩的字符形如：\xac\xed\x00\x05t\x00\x10 ,这就是默认keySerializer导致的，其它同理
