我怎样才能优雅地序列化一个lambda？
例如，下面的代码抛出一个NotSerializableException.如何在不创建SerializableRunnable"虚拟"接口的情况下修复它？
public static void main(String[] args) throws Exception {
File file = Files.createTempFile("lambda", "ser").toFile();
try (ObjectOutput oo = new ObjectOutputStream(new FileOutputStream(file))) {
Runnable r = () -> System.out.println("Can I be serialized?");
oo.writeObject(r);
}
try (ObjectInput oi = new ObjectInputStream(new FileInputStream(file))) {
Runnable r = (Runnable) oi.readObject();
r.run();
}
}
