Java SwingWorker已扩展，但GUI仍处于冻结状态

这是我第一次尝试将Swing组件用于GUI，我正在尝试实现一个允许用户运行2个异步远程命令的解决方案

简而言之，这两个命令是：

在远程服务器上执行命令

下载数据

我的问题是，虽然我雇佣了一个摇摆工人，但我的主菜单仍然冻结。此外，在添加第一个命令之前，将传递SwingWorker并执行第二个命令

我已经在网上浏览了很多很多的例子和解释，我觉得我仍然缺少一些关键的直觉，这些直觉可以让我成功

我的swing worker有什么问题，因为它仍然会冻结GUI，并且不会等到完成后再执行其余的代码

编辑：最终我还想创建一个进度条，显示任务完成前剩余的时间

GUI类-带按钮的基本GUI

public TestGUI(){
      //code to show Gui with buttons

      //code also contains mouse listener:  
     btn.addMouseListener(new MouseAdapter() { // listener
        @Override
        public void mousePressed(MouseEvent e){
            SampleClass.doRemoteTask();
        }

    });   

}

示例类-在后台使用Swing Worker运行远程命令

 public SampleClass(){

 public static void doRemoteTask(){
    //create sample worker
    final SampleWorker sampleworker = new SampleWorker(command, session); 

    //add change listener to wait for state change.
    sampleworker.addPropertyChangeListener(new PropertyChangeListener(){
        @Override
        public void propertyChange(PropertyChangeEvent event) {
            if(StateValue.DONE == sampleworker.getState()){
                try {
                    Integer i = sampleworker.get();
                } catch (InterruptedException | ExecutionException e) {
                    System.out.println("Could not get");
                    e.printStackTrace();
                }
            };
        }
    });

  //do other stuff after the state DONE
  sampleworker.execute(); //sample worker is a long task. This is why it was created in the Swing Worker. 
   }

}

protected Integer doInBackground() throws Exception {
    byte[] tmp=new byte[1024];
    int j = 0;
    publish("Start");
    while(true){
            //do stuff
            if(j % 100 == 0){
                setProgress(j);

        }
            //write to System.out then exit
            break;
        }
        try{Thread.sleep(1000);}catch(Exception ee){}
    }
    publish("Completed");

    return j;
}

示例工人类-在后台运行命令

 public SampleClass(){

 public static void doRemoteTask(){
    //create sample worker
    final SampleWorker sampleworker = new SampleWorker(command, session); 

    //add change listener to wait for state change.
    sampleworker.addPropertyChangeListener(new PropertyChangeListener(){
        @Override
        public void propertyChange(PropertyChangeEvent event) {
            if(StateValue.DONE == sampleworker.getState()){
                try {
                    Integer i = sampleworker.get();
                } catch (InterruptedException | ExecutionException e) {
                    System.out.println("Could not get");
                    e.printStackTrace();
                }
            };
        }
    });

  //do other stuff after the state DONE
  sampleworker.execute(); //sample worker is a long task. This is why it was created in the Swing Worker. 
   }

}

protected Integer doInBackground() throws Exception {
    byte[] tmp=new byte[1024];
    int j = 0;
    publish("Start");
    while(true){
            //do stuff
            if(j % 100 == 0){
                setProgress(j);

        }
            //write to System.out then exit
            break;
        }
        try{Thread.sleep(1000);}catch(Exception ee){}
    }
    publish("Completed");

    return j;
}

SampleClass.doRemoteTask（）我们不知道该方法的作用。该方法在EDT上调用，如果调用长时间运行的代码，可能会导致GUI冻结；在远程服务器上调用耗时的命令。我将编辑我的帖子，详细说明命令的类型以及进程挂起的位置。这正是导致GUI冻结的原因。该方法应该启动SwingWorker，SwingWorker将调用远程服务器上的命令。
