从java运行cmd并添加sql plus命令

Question

我正在使用2按钮Run and Commit处理应用程序。 当我按Run时，我的应用程序在sql plus中运行一个脚本。我的想法是，当我按下提交按钮时，我想保留在sql plus中并进行提交。我也希望看到每个命令的输出。事情正常，直到我按下提交。输出没有显示..

我的运行按钮操作：

package pachet1;
import java.util.Scanner;

import javafx.scene.control.TextArea;
import jcifs.smb.NtlmPasswordAuthentication;
import jcifs.smb.SmbFile;

import java.io.*;
import java.net.MalformedURLException;
import java.nio.file.Files;

public class MyExec {

    public static ProcessBuilder builder;
    public static Process p;
    public static BufferedReader bri;
    public static BufferedReader bre;
    public static   BufferedWriter p_stdin;

    public static void executeScript(String scriptName, String alias, String path, TextArea txtArea) throws IOException
    {

        NtlmPasswordAuthentication userCred = new NtlmPasswordAuthentication("domain",
                "username", "password");
        SmbFile smbFile=new SmbFile("path"  + scriptName, userCred);
        File file = new File("D://" + scriptName);
        try (InputStream in = smbFile.getInputStream()) {
            Files.copy(smbFile.getInputStream(), file.toPath());
        }
        //init shell
        builder = new ProcessBuilder( "cmd" );
        builder.redirectErrorStream(true);

        try {
            p = builder.start();
        }
        catch (IOException e) {
            //System.out.println(e);
        }
        //get stdin of shell
      p_stdin =
          new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));

        // execute the desired command (here: ls) n times
        int n=1;

            try {
                //single execution
            p_stdin.write("sqlplus sys/sys@" + alias +" as sysdba");
            p_stdin.newLine();
            p_stdin.flush();
            p_stdin.write("@"+file.toPath());
            p_stdin.newLine();
            p_stdin.flush();
//            p_stdin.write("commit;");
//            p_stdin.newLine();
//            p_stdin.flush();
            }
            catch (IOException e) {
            //System.out.println(e);
            }


        // finally close the shell by execution exit command
        try {
            p_stdin.write("");
            p_stdin.newLine();
            p_stdin.flush();
        }
        catch (IOException e) {
            System.out.println(e);
        }

    // write stdout of shell (=output of all commands)
        String line;
       bri = new BufferedReader
                (new InputStreamReader(p.getInputStream()));
               bre = new BufferedReader
                (new InputStreamReader(p.getErrorStream()));
              while ((line = bri.readLine()) != null) {
                txtArea.appendText(line + "\n");
                  System.out.println(line + "\n");
              }
              //bri.close();
              while ((line = bre.readLine()) != null) {
               txtArea.appendText(line + "\n");
                  System.out.println(line + "\n");

              }
              //bre.close();
              System.out.println("Done.");



    }
}

我的提交按钮操作：

 Thread t1 = new Thread(new Runnable() {
         public void run() {

            try {
                MyExec.p_stdin.write("commit");
                MyExec.p_stdin.newLine();
                MyExec.p_stdin.flush();
                MyExec.p_stdin.write("exit");
                MyExec.p_stdin.newLine();
                MyExec.p_stdin.flush();
                //txtArea.appendText("Commit complete.");
                 String line;
                    MyExec.bri = new BufferedReader
                            (new InputStreamReader(MyExec.p.getInputStream()));
                           MyExec.bre = new BufferedReader
                            (new InputStreamReader(MyExec.p.getErrorStream()));
                          while ((line = MyExec.bri.readLine()) != null) {
                            txtArea.appendText(line + "\n");
                              System.out.println(line + "\n");
                          }
                          MyExec.bri.close();
                          while ((line = MyExec.bre.readLine()) != null) {
                           txtArea.appendText(line + "\n");
                              System.out.println(line + "\n");

                          }
                          MyExec.bri.close();
                          System.out.println("Done.");

            } catch (IOException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }

         }
    });

    public void commit(ActionEvent e)
    {     

    t1.start();

    }

所以我需要在该线程中从运行按钮获取进程输出并继续显示它，但它不起作用..
