Question

我使用Channel.setOutputStream（System.out），现在我想在textArea中显示结果。我怎样才能做到这一点？这是我的代码：

 public static void main(String[] args) throws JSchException, InterruptedException {

    JSch jSch = new JSch();
    Session session = jSch.getSession(user , host , 22);
    session.setPassword(password);
    session.setConfig("StrictHostKeyChecking" , "no");
    session.connect(10*1000);
    System.out.println("Connected");

    Channel channel = session.openChannel("shell");
    InputStream is = new ByteArrayInputStream(command.getBytes());
    channel.setInputStream(is);
    channel.setOutputStream(System.out);

    channel.connect(15*1000);

    Thread.sleep(3*1000);

    channel.disconnect();
    session.disconnect();


}

感谢。

        if (b == '\n') {

            SwingUtilities.invokeLater(new Runnable() {
                @Override

                }

            sb.setLength(0);
            StringBuilder append;
            append = sb.append("").append("");

            return;
        }

        sb.append((char) b);
    }

    /**
     *
     * @return
     */
    public StringBuilder getSb() {
        return sb;
    }
}

在文本区域中显示OutputStream（System.out）
