如何在运行.exe文件时修复问题

Question

我ThMapInfratab1-2.exe在C:\Users\Infratab Bangalore\Desktop\Rod目录下有一个文件.我按照以下方式在命令提示符下执行.它工作正常.

 C:\Users\Infratab Bangalore\Desktop\Rod>ThMapInfratab1-2.exe TMapInput.txt

我想用Java技术做同样的程序.使用StackOverFlow伙伴,我试过两种方式.

情况1:

用getRuntime().

   import java.util.*;
   import java.io.*;
   public class ExeProcess
{
public static void main(String args[]) throws IOException
{
    Runtime rt = Runtime.getRuntime();
    File filePath=new File("C:/Users/Infratab Bangalore/Desktop/Rod");
    String[] argument1  = {"TMapInput.txt"};
    Process proc = rt.exec("ThMapInfratab1-2.exe", argument1, filePath);
}
}

案例2:

运用 ProcessBuilder

 import java.io.File;
 import java.io.IOException;
 public class ProcessBuilderSample {

 public static void main(String args[]) throws IOException 
 {
  String executable = "ThMapInfratab1-2.exe";
  String argument1  = "TherInput.txt";
  File workingDirectory = new File("C:/Users/Infratab Bangalore/Desktop/Rod");

  ProcessBuilder pb = new ProcessBuilder(executable, argument1);
  pb.directory(workingDirectory);
  pb.start();     
 }
 }

在这两种情况下,我收到以下错误.

错误:

   Exception in thread "main" java.io.IOException: Cannot run program "ThMapInfratab1-2.exe" (in directory "C:\Users\Infratab Bangalore\Desktop\Rod"): CreateProcess error=2, The system cannot find the file specified
at java.lang.ProcessBuilder.start(Unknown Source)
at ProcessBuilderSample.main(ProcessBuilderSample.java:16)
  Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified
at java.lang.ProcessImpl.create(Native Method)
at java.lang.ProcessImpl.<init>(Unknown Source)
at java.lang.ProcessImpl.start(Unknown Source)
... 2 more

我没弄明白,问题是什么.任何人都可以建议我.

我在用jre 7.

谢谢

Answer 1

试着用这个:

import java.io.File;
 import java.io.IOException;
 public class ProcessBuilderSample {

 public static void main(String args[]) throws IOException 
 {
  String executable = "ThMapInfratab1-2.exe";
  String argument1  = "TherInput.txt";
  File workingDirectory = new File("C:/Users/Infratab Bangalore/Desktop/Rod");

  ProcessBuilder pb = new ProcessBuilder("cmd", "/c","start" ,executable, argument1);
  pb.directory(workingDirectory);
  pb.start();     
 }
 }
