Windows系统中Java调用cmd命令及执行exe程序的方法_java

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！");
  }
 }
}
