我有一个简单的 GUI 程序，它与数据库进行一些交互，然后一旦完成 ftps 将一些文件上传到服务器。在我添加 SwingWorker 线程以保持 GUI 响应之前，这一直很有效。

如果我把它放在它的独立项目中，我正在使用的代码可以正常工作，但是在这个项目（SwingWorker 线程）中它给了我以下错误：

java.net.SocketException: Software caused connection abort: recv failed

有任何想法吗？

编辑：我假设你的意思是这样的？请注意这是一个非常精简的版本，我已经删除了很多多余的代码。我看不出有任何影响。

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");                 
    }
}

如前所述，我将这段代码放在 swingworker 中并将其放入自己的类中，它运行完美。
