Question

尝试使用Redis使用Java Netbeans构建实时UI，

Jedis jedis = new Jedis("192.168.0.180",6379);
    new Timer (0, new ActionListener() 
  {

        @Override
           public void actionPerformed(ActionEvent e){  

    date = new Date();
    SimpleDateFormat dateFormatter1 = new SimpleDateFormat("d MMMM yyyy  
    hh:mm:ss:SSS");
TimeZone istTimeZone = TimeZone.getTimeZone("Asia/Kolkata");
dateFormatter1.setTimeZone(istTimeZone);
jTextField4.setText (dateFormatter1.format(date));

    try {


    jTextField1.setText(jedis.get("model2"));
    jTextField2.setText(jedis.get("chr2"));
    jTextField3.setText(jedis.get("qr2"));
    if(jedis.get("me2").equals("1")){
    jLabel7.setBackground(Color.GREEN);
    }
     if(jedis.get("me2").equals("0")){
    jLabel7.setBackground(Color.RED);
    }
     if(jedis.get("me2").equals("2")){
    jLabel7.setBackground(Color.WHITE);
    }
     if(jedis.get("eq2").equals("1")){
    jLabel7.setBackground(Color.GREEN);
    }
     if(jedis.get("eq2").equals("0")){
    jLabel7.setBackground(Color.RED);
    }
     if(jedis.get("eq2").equals("2")){
    jLabel7.setBackground(Color.WHITE);
    }

    } catch(Exception ex){
             ex.printStackTrace();
             System.out.println();
    //JOptionPane.showMessageDialog(parent, "Server not connected");
  }
    }
        }).start();
}

UI持续更新值30分钟，直到套接字超时异常。

异常后，UI上的字段显示洗牌值示例：jTextField1.setText(jedis.get("model2"))显示jedis.get("eq2")

的值

请帮助我理解UI的异常行为，并建议解决异常。

使用的jar文件：jedis-2.8.1
