使用Redis进行对象存储，在处理业务逻辑的时候，丛Redis获取对象发现反序列化失败，抛出如下异常:

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

# 解决方案 #

经排查，原因是存放的对象忘了添加序列化号，导致存储的序列化编号和反序列化编号不一致，所以反序列化异常。

![这里写图片描述][70]

只需要把序列化编号添加上即可，记得清理Redis缓存：

private static final long serialVersionUID = 8841433872811285796L;
