Java RMI NoSuchObjectException
我有一个使用 Java RMI 的服务器和客户端。如果我使用一个客户端，下面的代码一切都很好。但是，如果我连接一个客户端，然后连接第二个客户端，它会抛出端口已在使用异常。没关系，所以我断开连接的客户端，然后尝试再次与第二个客户端连接。它给了我这个：
java.rmi.NoSuchObjectException：表中没有这样的对象
这是为什么？
//CONNECT
Registry registry = LocateRegistry.getRegistry(
Options.getRegistryIp(), Options.getRegistryPort());
server = (IServer) registry.lookup(Constants.MB_SERVER_NAME);
UnicastRemoteObject.exportObject(client, Options.getMyPort());
server.registerClient(client);
//DISCONNECT
server.removeClient(client, client.getUser());
UnicastRemoteObject.unexportObject(client, false);
I have a server and client using Java RMI. If I use one client all is fine with the code below. But if I connect with a client and then a second one, it throws port already in use exception. That's fine, so I disconnect the connected client and then try to connect with the second client again. It gives me this:
java.rmi.NoSuchObjectException: no such object in table
Why is this?
//CONNECT
Registry registry = LocateRegistry.getRegistry(
Options.getRegistryIp(), Options.getRegistryPort());
server = (IServer) registry.lookup(Constants.MB_SERVER_NAME);
UnicastRemoteObject.exportObject(client, Options.getMyPort());
server.registerClient(client);
//DISCONNECT
server.removeClient(client, client.getUser());
UnicastRemoteObject.unexportObject(client, false);

NoSuchObjectException 意味着存根引用了未导出的远程对象（无论是显式导出还是通过 GC 导出）。您是否在lookup（）、registerClient（）或removeClient（）上得到了这个？
NoSuchObjectException means that the stub refers to a remote object which has been unexported, either explicitly or via GC. Are you getting this on the lookup(), or the registerClient(), or the removeClient()?
