Windows中Java调用cmd命令及执行exe程序的方法

Java调用cmd命令，并输出显示信息:

package com.anxin.cmd.test;

  

import java.io.BufferedReader;

import java.io.InputStreamReader;

 

public class Command {

  

 public static void main(String[] args) {

  try {

   Runtime rt = Runtime.getRuntime();

   Process pr = rt.exec("cmd /c dir"); // cmd /c calc

   // Process pr = rt.exec("D:\\xunlei\\project.aspx");

  

   BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream(), "GBK"));

  

   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();

  }

 }

}

Java启动本机应用程序EXE的三种方式:

第一种方式：利用cmd方式  

/**

 * 执行cmd命令

 *

 * @param command

 * @throws IOException

 */

public static String executeCmd(String command) throws IOException {

 log.info("Execute command : " + command);

 Runtime runtime = Runtime.getRuntime();

 Process process = runtime.exec("cmd /c " + command);

 BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream(), "UTF-8"));

 String line = null;

 StringBuilder build = new StringBuilder();

 while ((line = br.readLine()) != null) {

  log.info(line);

  build.append(line);

 }

 return build.toString();

}

  

executeCmd(start "AXAdWebBrowser" "D:\AXAdsBrowser\AXAdWebBrowser.exe");

第二种方式：利用ProcessBuilder调用cmd方式

/**

 * 启动应用程序

 *

 * @param programName

 * @return

 * @throws IOException

 */

public static void startProgram(String programPath) throws IOException {

 log.info("启动应用程序：" + programPath);

 if (StringUtils.isNotBlank(programPath)) {

  try {

   String programName = programPath.substring(programPath.lastIndexOf("/") + 1, programPath.lastIndexOf("."));

   List<String> list = new ArrayList<String>();

   list.add("cmd.exe");

   list.add("/c");

   list.add("start");

   list.add("\"" + programName + "\"");

   list.add("\"" + programPath + "\"");

   ProcessBuilder pBuilder = new ProcessBuilder(list);

   pBuilder.start();

  } catch (Exception e) {

   e.printStackTrace();

   log.error("应用程序：" + programPath + "不存在！");

  }

 }

}

第三种方式：使用Desktop启动应用程序  

/**

 * 启动应用程序

 *

 * @param programName

 * @return

 * @throws IOException

 */

public static void startProgram(String programPath) throws IOException {

 log.info("启动应用程序：" + programPath);

 if (StringUtils.isNotBlank(programPath)) {

  try {

   Desktop.getDesktop().open(new File(programPath));

  } catch (Exception e) {

   e.printStackTrace();

   log.error("应用程序：" + programPath + "不存在！");

  }

 }

}
