/** * 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
