Question

我有一个简单的GUI程序，可以与数据库进行一些交互，然后在完成后将一些文件ftps到服务器。这一直很有效，直到我添加了一个SwingWorker线程来保持GUI响应。

我使用的代码工作正常，如果我把它放在它的独立项目中，但在这个项目（SwingWorker线程）中，它给了我以下错误：

有什么想法吗？

编辑：我猜你的意思是这样的？请注意这是一个非常精简的版本，我删除了很多多余的代码。我看不出任何影响这一点。

class Worker extends SwingWorker<Integer, Integer>{
    protected Integer doInBackground() throws Exception{
        FTPClient client = new FTPClient();
        client.connect(url);
        client.login(username, password);
        client.setPassive(false);
        client.changeDirectory(uploaddirectory);
        client.upload(new File(fileuploadpath));
        client.disconnect(true);
    }

    protected void done() {                
        System.out.println("Done");                 
    }
}

如上所述，我将此代码放在swingworker中并将其放在自己的类中，它运行得很完美。
