Java RMI 对象静态而不是静态字段？

Question

所以我有这个代码:

public class RemoteImpl extends UnicastRemoteObject implements TestRemote {

    private static final long serialVersionUID = 1L;
    private static int counter = 0;
    private int localizedCounter = 0;

    protected RemoteImpl() throws RemoteException {
        super();
    }

    @Override
    public int getMeGlobalCounter() throws RemoteException {
        counter++;
        return counter;
    }

    @Override
    public int getMeLocalizedCounter() throws RemoteException {
        localizedCounter++;
        return localizedCounter;
    }
}

对于我的客户，我正在尝试:

public class TestClient {

    public static void main(String[] args) throws Exception {
        Registry registry = LocateRegistry.getRegistry("localhost", Constant.RMI_PORT);
        TestRemote remote = (TestRemote) registry.lookup(Constant.RMI_ID);
        System.out.println("Global counter:" + remote.getMeGlobalCounter());
        System.out.println("Localized counter:" + remote.getMeLocalizedCounter());
    }

}

运行此代码两次后，我期望看到:

Global counter:3
Localized counter:1

但是我看到了

Localized counter:3

那么为什么每次调用此方法时本地化计数器都不会重置？我不是每次都会得到一个新对象吗？

Am I not getting a new object every time?

不，你不是。您将获得绑定(bind)到注册表中的相同实例。 RMI 不会随心所欲地创建远程对象。
