解决java.io.StreamCorruptedException: invalid stream header: 6F617574 redis

报错全称

java.io.StreamCorruptedException: invalid stream header: 6F617574
	at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:866)
	at java.io.ObjectInputStream.<init>(ObjectInputStream.java:358)

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.StreamCorruptedException: invalid stream header: 6F617574

代码

Cursor cursor = (Cursor) redisTemplate.executeWithStickyConnection(redisConnection -> new ConvertingCursor<>(redisConnection.scan(options), redisSerializer::deserialize));
...
cursor.next() // 这句报错

疑似产生的原因

很明显，解码错误。说明反序列化|解码器和序列化|编码器不匹配，不能前呼后应

弯路、坑

应看清错误详情

分析

存储该值的序列化方式应该和反序列化一致

解决方案

1） 修改redis config。重新设置值，再把值取出来，保持序列化、反序列化对应，成功了。
