1.远程执行导入dmp命令

public void linuxExecute(){
   //用户名
    String username="";
   //密码 
    String password="";
   //创建连接ip,端口(port)
   Connection conn =new Connection("IP",port);
  try{
   //连接
   conn.connect();
   //验证用户名密码是否正确
   boolean UserPwd =conn.authenticateWithPassword(username,password);
   
   if(UserPwd){
     //创建session会话
     Session session =conn.openSession();
     //建立虚拟终端
     session.requestPTY("bash");
     //打开一个shell
     session.startShell();
     //将屏幕上的文字全部打印出来
     InputStream stdOut=new  StreamGobbler(session,getStdout()); 
     BufferedReader stdoutReader = new BufferedReader(new InputStreamReader(stdOut));
     //准备输入命令
     try(PrintWriter out =new PrintWriter(session.getStdin())){
      //输入待执行命令
      out.println("imp 数据库用户名/密码@实例名 file=文件路径 full=y ignore=y; ");
      out.println("exit");
     }
     //等待，除非1.连接关闭，2.输入数据传送完毕 ，3.进程状态为退出
       session.waitForCondition(ChannelCondition.CLOSED | ChannelCondition.EOF | 
       ChannelCondition.EXIT_STATUS);
     //读取数据进入死循环
     while (true){
                    String line = stdoutReader.readLine();
                    if (line == null) {
                        break;
                    }
                    System.out.println(line);
                }
   }catch (Exception e) {
            e.printStackTrace();
        } finally {
            conn.close();
     }
 
  }
}
