背景

日常开发中总能遇到一些奇怪的需求，例如使用java执行cmd命令或者bat批处理文件，今天就简单记录一下使用过程。

使用

废话不多说直接上代码

import java.io.BufferedReader; import java.io.FileWriter; import java.io.IOException; import java.io.InputStreamReader; public class Cmder { /** * 执行一个cmd命令 * * @param cmdCommand cmd命令 * @return 命令执行结果字符串，如出现异常返回null */ public static String executeCmdCommand(String cmdCommand) { StringBuilder stringBuilder = new StringBuilder(); Process process = null; try { process = Runtime.getRuntime().exec(cmdCommand); BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(process.getInputStream(), "GBK")); String line = null; while ((line = bufferedReader.readLine()) != null) { stringBuilder.append(line).append(" "); } return stringBuilder.toString(); } catch (Exception e) { e.printStackTrace(); return null; } } /** * 执行bat文件， * * @param file bat文件路径 * @param isCloseWindow 执行完毕后是否关闭cmd窗口 * @return bat文件输出log */ public static String executeBatFile(String file, boolean isCloseWindow) { String cmdCommand = null; if (isCloseWindow) { cmdCommand = "cmd.exe /c " + file; } else { cmdCommand = "cmd.exe /k " + file; } StringBuilder stringBuilder = new StringBuilder(); Process process = null; try { process = Runtime.getRuntime().exec(cmdCommand); BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(process.getInputStream(), "GBK")); String line = null; while ((line = bufferedReader.readLine()) != null) { stringBuilder.append(line).append(" "); } return stringBuilder.toString(); } catch (Exception e) { e.printStackTrace(); return null; } } /** * 执行bat文件,新开窗口 * * @param file bat文件路径 * @param isCloseWindow 执行完毕后是否关闭cmd窗口 * @return bat文件输出log */ public static String executeBatFileWithNewWindow(String file, boolean isCloseWindow) { String cmdCommand; if (isCloseWindow) { cmdCommand = "cmd.exe /c start" + file; } else { cmdCommand = "cmd.exe /k start" + file; } StringBuilder stringBuilder = new StringBuilder(); Process process; try { process = Runtime.getRuntime().exec(cmdCommand); BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(process.getInputStream(), "GBK")); String line; while ((line = bufferedReader.readLine()) != null) { stringBuilder.append(line).append(" "); } return stringBuilder.toString(); } catch (Exception e) { e.printStackTrace(); return null; } } /** * 执行bat脚本 * * @param batScript 脚本内容 * @param location 脚本存储路径 * @return 结果 */ public static String executeBatScript(String batScript, String location) { StringBuilder stringBuilder = new StringBuilder(); FileWriter fw = null; try { //生成bat文件 fw = new FileWriter(location); fw.write(batScript); fw.close(); } catch (IOException e) { e.printStackTrace(); } Process process; try { process = Runtime.getRuntime().exec(location); BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(process.getInputStream(), "GBK")); String line; while ((line = bufferedReader.readLine()) != null) { stringBuilder.append(line).append(" "); } return stringBuilder.toString(); } catch (Exception e) { e.printStackTrace(); return null; } } /** * 执行脚本,不停止,并输出执行结果 * * @param batScript 脚本内容 * @param location bat文件生成地址 */ public void executeBatScriptAlways(String batScript, String location) { FileWriter fw = null; try { //生成bat文件 fw = new FileWriter(location); fw.write(batScript); fw.close(); } catch (IOException e) { e.printStackTrace(); } StringBuilder stringBuilder = new StringBuilder(); //运行bat文件 Process process; try { process = Runtime.getRuntime().exec(location); BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(process.getInputStream(), "GBK")); String line; while ((line = bufferedReader.readLine()) != null) { System.out.println(line); } } catch (Exception e) { e.printStackTrace(); } } } 复制代码
