   jason :

   another way to generate serialVersionUID(only for jdk1.6 or higher) :

   		// compile the java source code in the memory
   		JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
   		DiagnosticCollector diagnostics = new DiagnosticCollector();
   		JavaFileObject file = new JavaSourceFromString("com.xx.yy.HelloWord", "java source string here");
   		Iterable compilationUnits = Arrays.asList(file);
   		JavaCompiler.CompilationTask task = compiler.getTask(null, null, diagnostics, null, null, compilationUnits);
   		if (task.call()) {
   			ObjectStreamClass osc = ObjectStreamClass.lookupAny(Class.forName("com.xx.yy.HelloWord"));
   			long svuid = osc.getSerialVersionUID();
   		}
   ======================================
   public class JavaSourceFromString extends SimpleJavaFileObject {
    
   	private String code;
    
   	public JavaSourceFromString(String name, String code) {
   		super(URI.create("string:///" + name.replace('.', '/') + Kind.SOURCE.extension), Kind.SOURCE);
   		this.code = code;
   	}
    
   	public CharSequence getCharContent(boolean ignoreEncodingErrors) {
   		return code;
   	}
   }

   Understand the serialVersionUID | Java Best Practices :

   [...] You can use JDK “serialver” or Eclipse IDE to generate serialVersionUID automatically, see detail. [...]
