案例

使用Redis進行物件儲存，在處理業務邏輯的時候，叢Redis獲取物件發現反序列化失敗，丟擲如下異常:

Caused by: 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

解決方案

經排查，原因是存放的物件忘了新增序列化號，導致儲存的序列化編號和反序列化編號不一致，所以反序列化異常。

只需要把序列化編號新增上即可，記得清理Redis快取：

private static final long serialVersionUID = 8841433872811285796L;
