Serialization problem reported when loading class

 

 

Serialization problem reported when loading class

1. The serialization interface is not implemented, and the serial number is added.

2. The service implements or inherits the serialization interface, and the subclass implements it

2. The subclass uses toString()

 

Added a toString() implementation, so the internal jvm-auto-calculated 

serialVersionUID is different from before.

 

due to

The key class implements Externalizable, so the implementation may also change once:

 

3, different jvm versions
