how resolve java.io.InvalidClassException: local class incompatible: stream classdesc serialVersionUID [duplicate]

serialization

I have a class serializable in a so big project coded without specify serialVersionUID, and save in a dataBase MySQL as a blob!

I have to add some fields to this class, but after doing this, I get an exception like this:

IOException: error when reading object
org.datanucleus.exceptions.NucleusUserException:
IOException: error when reading object at
org.datanucleus.store.rdbms.datatype.BlobImpl.getObject(BlobImpl.java:134)

.
. 
..

Caused by: java.io.InvalidClassException:
local class incompatible: stream classdesc serialVersionUID = 1113799434508676095,
local class serialVersionUID = -8504143738844344601 at
java.io.ObjectStreamClass.initNonProxy(ObjectStreamClass.java:560)

This is all the stackTrace:

Why do we declare serialVersionUID in Java?

Simply put, we use the serialVersionUID attribute to remember versions of a Serializable class to verify that a loaded class and the serialized object are compatible. The serialVersionUID attributes of different classes are independent. Therefore, it is not necessary for different classes to have unique values.

What is serialVersionUID in Java exception?

The serialization at runtime associates with each serializable class a version number called a serialVersionUID, which is used during deserialization to verify that the sender and receiver of a serialized object have loaded classes for that object that are compatible with respect to serialization.

What does serialVersionUID mean?

SerialVersionUID is a unique identifier for each class, JVM uses it to compare the versions of the class ensuring that the same class was used during Serialization is loaded during Deserialization. Specifying one gives more control, though JVM does generate one if you don't specify.

When should I update serialVersionUID?

The value of the serialVersionUID field should ideally be changed when incompatible changes are made to the structure of the class. The complete list of incompatible changes is present in the Java Object Serialization Specification.

1 Answers

Define a member in the class concerned:

private static final long serialVersionUID = 1113799434508676095L;

This solves the problem described in the message, by forcing the serialVersionUID of the local class to match what was put in the stream when you serialized the old version of the class, which would have been computed automatically over various class attributes if no serialVersionUUD field was present at that time.

It is possible that you altered the class in an incompatible way, which will then produce a different exception. See the Object Serialization Specification chapter on Versioning for details. However merely adding or removing a field doesn't have that effect.
