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！"); 
  } 
 } 
}
