Как разрешить java.io.InvalidClassException: локальный класс несовместим: stream classdesc serialVersionUID

Question

У меня есть сериализуемый класс в таком большом проекте, кодированном без указания serialVersionUID, и сохраняйте в базе данных MySQL как blob!

Я должен добавить несколько полей в этом классе, но после того, как делать это, я получаю исключение, как это:

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) 

Это все StackTrace:

Кто есть идея о решении этой проблемы.

Answer 1

Определения члена в классе заинтересованный:

private static final long serialVersionUID = 1113799434508676095L; 

Это решает проблему, описанную в сообщении, заставив serialVersionUID локального класса соответствует тому, что было введено в потоке, когда вы сериализовать старую версию класса, который автоматически вычислялся бы по различным атрибутам класса, если в это время не было поля serialVersionUUD.

Возможно, вы изменили класс несовместимым образом, который затем будет производить другое исключение. Подробнее см. В главе «Спецификация сериализации объектов». Однако простое добавление или удаление поля не имеет такого эффекта.

Answer 2

Вы можете реализовать частный объект readObject (ObjectInputStream in) в своем классе объектов. Это вроде как «переопределяет» поведение по умолчанию, хотя оно объявлено как «личное», поэтому технически это не должно. В принципе, когда Java-сериализатору необходимо прочитать объект из потока, класса, который реализовал этот метод, он будет вызывать это вместо того, чтобы выполнять свою задачу по умолчанию.

Итак, вы можете реализовать в нем логику, которая будет считывать все существующие поля из потока и присваивать значения по умолчанию тем, которые отсутствуют.

Редактировать: Как @EJP указывает (спасибо, @EJP!), Это не совсем работает. Вы также должны определить private static long serialVersionUID в своем классе и установить его в значение «old», которое вы видите в исключении.

Также рассмотрите возможность замены Serializable на Externalizable на будущее, это даст вам дополнительную гибкость и прозрачность. Расширение Externalizable сообщает java, что вы намерены обрабатывать сериализацию самостоятельно, и она не будет пытаться выполнить свою задачу по умолчанию, которая выдает исключение.

В этом случае реализуйте readExternal(ObjectInputStream in), чтобы читать члены потока один за другим и инициализировать те, которые отсутствуют для какого-либо значения по умолчанию.
