Get serial version UID
serialver [ClassName]
With classpath
serialver -classpath [path] [ClassName]
Show for JAR class
serialver -classpath [app.jar] [com.example.MyClass]
说明
serialver computes and displays the serialVersionUID for Java classes that implement the Serializable interface. This UID is a hash derived from the class structure (fields, methods, interfaces) and is used by Java's serialization mechanism to verify that sender and receiver of a serialized object have compatible class definitions. When a class does not explicitly declare a serialVersionUID, the JVM computes one automatically at runtime. Using serialver to obtain and hardcode this value in the class source prevents incompatible class version errors when the class structure changes in ways that remain compatible with older serialized forms.

- -classpath _PATH_
- Class search path.
- -J _FLAG_
- Pass option to the Java runtime (e.g., -J-Xms48m).

How do I run a basic serialver example?
Run `serialver [ClassName]` in a terminal, then adjust file names, paths, flags, or remote targets for your system.
What does -classpath _PATH_ do in serialver?
Class search path.
