定义工具类
public class CommandUtils{ /** * command 要执行的文件或命令 call回调函数 **/ public static void exec(String command,ICommandCall call){ try{ if(StringUtils.isEmpty(command)){ log.error("没有要执行的命令。。"); return; } StringBuffer cmd = new StringBuffer(); //获取操作系统标识 String osName = System.getProperty(os.name); if(os.startsWith(Window)){ //window实现（利用比拟少 不展现具体内容） }else if(osName.equals("Linux")){ //linux实现 cmd.append("sh "); cmd.append(command); cmd.append(" &"); } String cmds = cmd.toString(); log.info("启动执行："+cmds); Process process = Runtime.getRuntime().exec(cmds); printMessage(process.getInputStream(),call); int waitFor = process.waitFor(); log.info("waitFor:"+waitFor); process.destroy(); }catch(Exception e){ log.error(e.getMessage(),e); } } //读取输出流办法 static void printMessage(final InputStream inputStream,ICommand call){ Thread thread = new Thread(new Runnable(){ @override public void run(){ try{ //获取以后工夫点 Instant start = DateUtils.instant(); Reader reader = new InputSteamReader(inputSteam); BufferedReader bufferedReader = new BufferedReader(reader); String line = ""; while((line = befferedReader.readLine()) != null){ log.info(line); //获取两分钟之后的工夫点 Long durationMinutes = DateUtils.getDurationMinues(start,DateUtils.minute); //判断以后工夫点是否大于两分钟 if(durationMinutes == Long.valueOf(2)){ log.info("调用超时。。"); break; }else{ //执行调用逻辑 if(StringUtils.contains(line,"stop success")){ //承受到返回值命令退出 并解决绝对应的业务逻辑 break; } } } if(call != null){ //如果定义了回调函数 执行 call.call(); } //敞开流 bufferedReader.close(); }catch(){ log.error("异样："+e.getMessage()); } } }); thread.start(); thread.join(); //阻塞主线程 期待主线程执行完 }}留神: 定义工具类时可依据本身须要，是否抉择解决多线程问题，是否须要返回值决定回调函数进行哪些封装须要，肯定要设置超时工夫防止线程无奈退出！
应用
public void test(){ Thread t = new Thread(()->{ //以linux门路 为例，启动某个tomcat服务 CommandUtils.exec("/data/test/start.sh",null); }); t.start(); t.join();}通过线程触发不影响办法整体返回值，对子线程进行阻塞，如果超时子线程也会进行退出，不影响下层办法的调用。
