有没有办法反序列化 Runnable？ [复制]

Question

上下文：

所以我有一个要保存到文本文件中的方法调用。这样做的目的是将可运行的序列化对象保存到文本文件中，然后从文本文件中获取它以执行。

final Runnable runnable = () -> { //Runnable object to serialize
      client.publish("me/feed", GraphResponse.class,
                        Parameter.with("message", statusMessage));
 };

final String gson = new Gson().toJson(runnable); // Serialized runnable as json. This works successfully.

final Runnable x = new Gson().fromJson(gson, Runnable.class); // error

错误是：

java.lang.RuntimeException: Unable to invoke no-args constructor for interface java.lang.Runnable. Registering an InstanceCreator with Gson for this type may fix this problem.

我理解错误，Runnable 是一个接口，它不能被序列化。但是，我还能做些什么来解决我的问题吗？

解决方案尝试 1. 错误

public class RunnableImplementation implements Runnable, Serializable {

Runnable runnable;

public RunnableImplementation() {

}

public RunnableImplementation(final Runnable runnable) {
    this.runnable = runnable;
}

@Override
public void run() {
    runnable.run();
  }
}

public class ExampleClass {

public static void main(String[] args) {
    final Runnable runnable = () -> {
        client.publish("me/feed", GraphResponse.class,
                Parameter.with("message", statusMessage));
    };

    RunnableImplementation x = new RunnableImplementation(runnable);

    String gson = new Gson().toJson(x);
    RunnableImplementation runnableImplementation = new Gson().fromJson(gson, RunnableImplementation.class); // causes same error as above
}
}

我可以向您推荐的一个盲目尝试是创建一些可运行的实现并使用它来尝试您的代码。例如：

    public class Main {

    public static void main(String[] args) {

        Runnable a = new A();

        String gson = new Gson().toJson(a);
        Runnable runnable = new Gson().fromJson(gson, A.class);

        runnable.run();
    }

    public static class A implements Runnable{

        public void run() {
            System.out.println("Here im");
        }



    }
}

顺便说一句，将我的 System.out.println("Here im"); 替换为 yours client.publish
