java怎样调用外部程序，程序的名称中有空格

[healer_kx]

Runtime.getRuntime().exec()

空格不是问题。看Java DOC

[congliu]

刚好以前写过，调用windows的net send，已经包含空格，请参考

import java.util.*;
import java.io.*;

class StreamGobbler extends Thread
{
InputStream is;
String type;

StreamGobbler(InputStream is, String type)
{
this.is = is;
this.type = type;
}

public void run()
{
try
{
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line=null;
while ( (line = br.readLine()) != null)
System.out.println(type + ">" + line);
} catch (IOException ioe)
{
ioe.printStackTrace();
}
}
}

public class GoodWindowsExec
{
public static void main(String args[])
{
int times=100;
if (args.length < 1)
{
System.out.println("USAGE: java GoodWindowsExec <cmd>");
System.exit(1);
}

try
{ for(int i=0;i<=times;i++){
String osName = System.getProperty("os.name" );
String[] cmd = new String[3];

if( osName.equals( "Windows 2000" ) )
{

cmd[0] = "cmd.exe" ;
cmd[1] = "/C" ;
cmd[2] = args[0];


}
else if( osName.equals( "Windows 95" ) )
{
cmd[0] = "command.com" ;
cmd[1] = "/C" ;
cmd[2] = args[0];
}

Runtime rt = Runtime.getRuntime();
System.out.println("Execing " + cmd[0] + " " + cmd[1]
+ " " + cmd[2]);
Process proc = rt.exec(cmd);
// any error message?
StreamGobbler errorGobbler = new
StreamGobbler(proc.getErrorStream(), "ERROR");

// any output?
StreamGobbler outputGobbler = new
StreamGobbler(proc.getInputStream(), "OUTPUT");

// kick them off
errorGobbler.start();
outputGobbler.start();




// any error???
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
}
} catch (Throwable t)
{
t.printStackTrace();
}
}
}

如果要运行C://run test.bat
可以用 new ProcessBuilder("\"C:/run test.bat\"").start();

[kamhung]

参数当中有空格的话, 需要用引号引起来
