本文详细解析了在使用Spring框架操作Redis时遇到的SerializationFailedException和InvalidClassException异常，主要原因是序列化时的序列号与反序列化时的序列号不一致。文章提供了在实体类中明确指定serialVersionUID的解决方案，确保序列化和反序列化的序列号一致。

之前存入Redis中的数据再次取时同时出现

SerializationFailedException和InvalidClassException

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.InvalidClassException: com.crazyape.other.entity.Notice;
 local class incompatible: 
 stream classdesc serialVersionUID = 8655127975488226493, 
 local class serialVersionUID = 5860155642145136340
 
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.InvalidClassException: com.crazyape.other.entity.Notice; 
local class incompatible: stream classdesc serialVersionUID = 8655127975488226493,
local class serialVersionUID = 5860155642145136340

Caused by: java.io.InvalidClassException: com.crazyape.other.entity.Notice; 
local class incompatible: 
stream classdesc serialVersionUID = 8655127975488226493,
local class serialVersionUID = 5860155642145136340

报异常的主要原因是：

通过序列化存入Redis中的序列数与我反序列化要拿的序列数不一致
换句话说就是存入Redis里的序列数和我创建类的序列数不一致

解决方法：

在操作的实体类中加入静态变量serialVersionUID

private static final long serialVersionUID = 8655127975488226493L;

serialVersionUID的值与序列化时的序列值保持一致

总结：

实现Serializable接口时推荐显式的声明serialVersionUID
