Question

Add serialVersionUID automatically to all classes

Asked by: nerdmike

HI

I'm dealing with some really old Java code in Eclipse with several classes that implement serializable but do not have a serialVersionUID defined.

Normally I would just allow eclipse to generate serialVersionUID for me by doing "ctrl+1" + "Add generated serial version." The problem is that I'm dealing with hundreds and hundreds of classes, I don't want to have to do this manually for each class, is it possible to have Eclipse do it automatically for all classes in a Project?

Hi,

I think you could write a code to that for you. Something like this:

File srcDir = new File("directory where your source files are");
File[] srcFiles = list all java source files in the srcDir directory and its subdirectories (there's a class to do that here: http://snippets.dzone.com/posts/show/1875)

Then, for each file in the array,  you check if the text "implements Serializable" or "implements java.io.Serializabie" is present.
So, just below the class declaration, you add the following line:

"private static final long serialVersionUID = " + ObjectStreamClass.getSerialVersionUID(CLASS OF CURRENT FILE IN THE ARRAY) + "L;"

Depending on the number of classes you have, I think it is worth it to try.
Don't know if it will work, though.
