Windows系統中Java調用cmd命令及執行exe程式的方法_java

Java調用cmd命令，並輸出顯示資訊:

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啟動本機應用程式EXE的三種方式:

第一種方式：利用cmd方式 

/**  * 執行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"); 

第二種方式：利用ProcessBuilder調用cmd方式

/**  * 啟動應用程式  *  * @param programName  * @return  * @throws IOException  */ public static void startProgram(String programPath) throws IOException {  log.info("啟動應用程式：" + 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("應用程式：" + programPath + "不存在！");   }  } } 

第三種方式：使用Desktop啟動應用程式 

/**  * 啟動應用程式  *  * @param programName  * @return  * @throws IOException  */ public static void startProgram(String programPath) throws IOException {  log.info("啟動應用程式：" + programPath);  if (StringUtils.isNotBlank(programPath)) {   try {    Desktop.getDesktop().open(new File(programPath));   } catch (Exception e) {    e.printStackTrace();    log.error("應用程式：" + programPath + "不存在！");   }  } }
