在我看来,这是编译器或JVM中的一个错误,但也许有人有更好的解释.

下面的代码运行正常,但如果我取消注释第二个runnable初始化,直接使用'this',它不能反序列化对象(in.readObject()抛出异常).

public class TestClass implements Serializable {
    String               msg = "HEY!";
    SerializableRunnable runnable;
    public TestClass() {
        TestClass self = this;
        runnable = () -> self.say();  // uses a local copy of 'this'
       // runnable = () -> this.say(); // uses 'this' directly
    }
    public void say() {
        System.out.println(msg);
    }
    public static void main(String[] args) throws Exception {
        ByteArrayOutputStream buffer = new ByteArrayOutputStream();
        try (ObjectOutputStream out = new ObjectOutputStream(buffer)) {
            out.writeObject(new TestClass());
        }
        try (ObjectInputStream in …

在了解JSP和servlet时,我听说了重定向和调度.Wicket的setResponsePage()表演中有哪些？
