如何解决 java.io.InvalidClassException: local class incompatible: stream classdesc serialVersionUID

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

提问by ATEF CHAREF

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

我在一个如此大的项目中编写了一个可序列化的类，而没有指定 serialVersionUID，并将其作为 blob 保存在数据库 MySQL 中！

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

我必须向这个类添加一些字段，但是在这样做之后，我得到了这样的异常：

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:

这是所有的堆栈跟踪：

Define a member in the class concerned:

在相关类中定义一个成员：

private static final long serialVersionUID = 1113799434508676095L;

This solves the problem described in the message, by forcing the serialVersionUIDof 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 serialVersionUUDfield was present at that time.

这解决了消息中描述的问题，通过强制serialVersionUID本地类的 匹配在您序列化该类的旧版本时放入流中的内容，如果serialVersionUUD在那时。

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.

您可能以不兼容的方式更改了类，这将产生不同的异常。有关详细信息，请参阅有关版本控制的对象序列化规范一章。但是，仅添加或删除字段不会产生这种效果。

回答by Dima

You can implement private readObject(ObjectInputStream in) in your object class. It kinda "overrides" the default behavior, even though it is declared as "private", so technically it should not. Basically, when java serializer needs to read an object from a stream, of class that has this method implemented, it will call that instead of doing its default thing.

您可以在对象类中实现私有 readObject(ObjectInputStream in)。它有点“覆盖”默认行为，即使它被声明为“私有”，所以从技术上讲它不应该。基本上，当 java 序列化程序需要从实现了此方法的类的流中读取对象时，它将调用它而不是执行其默认操作。

So, you can implement a logic into it, that will read all the existing fields from the stream, and assign default values to those that are missing.

因此，您可以在其中实现一个逻辑，该逻辑将从流中读取所有现有字段，并将默认值分配给那些缺失的字段。

Edit:As @EJP points out (thanks, @EJP!), this does not quite work. You also need to defineprivate static long serialVersionUIDin your class, and set it to the "old" value you see in the exception.

编辑：正如@EJP 指出的（谢谢，@EJP！），这不太有效。您还需要private static long serialVersionUID在您的类中定义，并将其设置为您在异常中看到的“旧”值。

Also, consider replacing Serializable with Externalizable for the future, it gives you some more flexibility, and transparency. Extending Externalizabletells java that you intend to handle serialization yourself, and it will then not attempt to do its default thing that throws the exception.

另外，考虑将来用 Externalizable 替换 Serializable，它为您提供更多的灵活性和透明度。扩展Externalizable告诉 java 您打算自己处理序列化，然后它不会尝试执行引发异常的默认操作。

In that case, implement readExternal(ObjectInputStream in)to read members from the stream one-by-one, and initialize those that are missing to some kind of default.

在这种情况下，实现readExternal(ObjectInputStream in)从流中逐个读取成员，并将那些缺少的成员初始化为某种默认值。
