有两种方法,第一种是直接 Runtime.getRuntime().exec("...").
这里推荐第二种,可以得到输出和返回值:源代码如下:
import java.io.BufferedReader.
import java.io.InputStream.
import java.io.InputStreamReader.
public class ExecPerl {
public static void main(String args[]) {
String[] cmd = { "C:\\cygwin\\bin\\perl.exe", "sample.pl", "param1", "param2" }.
StringBuffer resultStringBuffer = new StringBuffer().
String lineToRead = "".
// get Process to execute perl, get the output and exitValue
int exitValue = 0.
try {
Process proc = Runtime.getRuntime().exec(cmd).
InputStream inputStream = proc.getInputStream().
BufferedReader bufferedRreader = new BufferedReader(new InputStreamReader(inputStream)).
// save first line
if ((lineToRead = bufferedRreader.readLine()) != null) {
resultStringBuffer.append(lineToRead).
}
