Java定时器只触发一次（服务器唯一的问题）

好吧，这是一个奇怪的，它似乎不是一个编码问题。 我有我的家用电脑和我的服务器电脑上安装Intellij（都运行Windows专业版）。 我在遥远的地方并肩而行。 无论是与Intellij打开和两个相同的副本和粘贴代码。 在我的家用电脑上，这个代码完美的工作，每60秒会启动一次。 但在服务器计算机上，它会一次点燃，而且不会再次启动。 我已经把它打包成一个jar子，运行jar子和相同的东西，它运行一次，永远不会再运行。 这是代码。

public class BackupTask extends TimerTask { private static final ThreadLocal<DateFormat> df = new ThreadLocal<DateFormat>(){ @Override protected DateFormat initialValue() { return new SimpleDateFormat("yyyy-MM-dd HH_mm_ss"); } }; public void run() { try { File src = new File("C:\\Users\\justi\\Desktop\\Server\\Saved"); File dest = new File("\\\\READYSHARE\\USB_Storage\\Backups\\" + df.get().format(Calendar.getInstance().getTime())); if(!dest.exists()){ dest.mkdir(); } copyFolder(src, dest); }catch(Exception e){ System.out.println("Error: " + e); } } public static void copyFolder(File src, File dest) throws IOException{ if(src.isDirectory()){ //if directory not exists, create it if(!dest.exists()){ dest.mkdir(); } //list all the directory contents String files[] = src.list(); for (String file : files) { //construct the src and dest file structure File srcFile = new File(src, file); File destFile = new File(dest, file); //recursive copy copyFolder(srcFile,destFile); } }else{ //if file, then copy it //Use bytes stream to support all file types InputStream in = new FileInputStream(src); OutputStream out = new FileOutputStream(dest); byte[] buffer = new byte[1024]; int length; //copy the file content in bytes while ((length = in.read(buffer)) > 0){ out.write(buffer, 0, length); } in.close(); out.close(); } } } 

AutoBackup.java

 public class AutoBackup { // Timer timer; private final ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1); private final int TIME_BETWEEN_SAVES = 60; public AutoBackup(){ final ScheduledFuture<?> beeperHandle = scheduler.scheduleAtFixedRate(new BackupTask(), 10, TIME_BETWEEN_SAVES, TimeUnit.SECONDS); } public static void main(String[] args) { new AutoBackup(); // Timer timer = new Timer(); // timer.schedule(new BackupTask(), 1000, 60 * 1000); } } 

这个程序只是一个非常简单的复制和粘贴从一个位置到另一个按计划的时间间隔。 我也尝试运行Intellij作为pipe理员，我只是出于为什么会发生这种想法。 服务器电脑有一个核心i5-4690k，Micro ITX技嘉超耐用GA-H97N-WIFI H97主板与16演出公羊。 让我知道是否有任何其他信息将有所帮助。

• 如何同时运行java 6和java 7
• Windows Server 2012 R2 – 错误：服务器pipe理器正在收集库存数据。 数据收集完成后，该向导将可用
• 使用“1”参数调用“发送”的exception：“根据validation过程，远程证书无效。PowerShell
• 在Windows Server 2016 TP4上安装Docker
• 在SendGrid.Net使用SmartHost的IIS SMTP

 Executors.newScheduledThreadPool(1); 

 scheduler.scheduleAtFixedRate(new BackupTask(), 10, 60, TimeUnit.SECONDS); 

 public static void copyFolder(File src, File dest) throws IOException{ if (src.isDirectory()) { //if directory not exists, create it if(!dest.exists()){ System.out.println("Creating directory " + dest); dest.mkdir(); System.out.println("Created directory "); } for (String file : src.list()) { File srcFile = new File(src, file); File destFile = new File(dest, file); System.out.println("Copying " + srcFile + " to " + destFile); copyFolder(srcFile,destFile); System.out.println("Copied " + srcFile + " to " + destFile); } }else{ InputStream in = new FileInputStream(src); OutputStream out = new FileOutputStream(dest); byte[] buffer = new byte[1024]; System.out.println("Writing file " + src + " to " + dest); int length; //copy the file content in bytes while ((length = in.read(buffer)) > 0){ out.write(buffer, 0, length); } System.out.println("Closing file " + src); in.close(); System.out.println("Closing file " + dest); out.close(); System.out.println("Writing file " + src + " to " + dest + " is done"); } } 

 InputStream in = null; OutputStream out = null; byte[] buffer = new byte[1024]; int length; try { in = new FileInputStream(src); out = new FileOutputStream(dest); while ((length = in.read(buffer)) > 0) { out.write(buffer, 0, length); } } finally { if (in != null) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } if (out != null) { try { out.close(); } catch (IOException e) { e.printStackTrace(); } } }
