Windows系统中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！");
 }
}
}
