JAVA PHP 调用cmd命令

一、JAVA调用CMD并输出结果

import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;

public class TestJar {
	public static void main(String[] s) {
		try {
			Runtime rt = Runtime.getRuntime();
			Process pr = rt
					.exec("java -jar D://testJar.jar D://中文.txt D://yx.txt");

			BufferedReader input = new BufferedReader(new InputStreamReader(
					pr.getInputStream(), "GBK"));//cmd命令输出的中文是GBK编码

			String line = null;

			while ((line = input.readLine()) != null) {
				System.out.println(line);
			}

			int exitVal = pr.waitFor();
			System.out.println("Exited with error code " + exitVal);

		} catch (Exception e) {
			System.out.println(e.toString());
			e.printStackTrace();
		}
	}

	public static void main2(String[] s) {
		for (String str : s) {
			try {
				TestJar.createFile(str);
				System.out.println(str);
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
	}

	public static void createFile(String fileName) throws Exception {
		try {
			File file = new File(fileName);
			if (!file.exists()) {
				file.createNewFile();
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

二、PHP调用CMD并输出结果

$comm = "java -jar D://testJar.jar D://x.txt D://y.txt";
        $result = system($comm,$re);
        var_dump($result);
        var_dump($re);

其中

java -jar D://testJar.jar D://x.txt D://y.txt

这个命令，是调用我自己的.jar包

观众老爷可以改成 ipconfig 来看运行结果
