WatchService for Java 6 [英] WatchService for Java 6

问题描述

Java 7引入了 WatchService 来持续监视文件系统。有没有Java 6的后端？

是否有纯Java库具有相似的功能？

解决方案

是的，当然。 Apache VFS正是这样做的。你可以在 http://commons.apache.org/vfs/ 找到它。它是一个纯Java库，可以监视文件，使用起来非常简单：

  FileSystemManager manager = VFS.getManager（）; 
 FileObject file = manager.resolveFile（c：/MyFile.txt）; 
 
 DefaultFileMonitor fm = new DefaultFileMonitor（new MyListener（））; 
 fm.setDelay（5000）; 
 fm.addFile（file）; 
 fm.start（）; 
  

上面的代码会监视文件c：/MyFile.txt。如果它改变，则调用对象new MyListener（）。

Java 7 introduced WatchService for monitoring file systems continuously. Is there a backport for Java 6 ?

Are there pure Java libraries with similar features ?

解决方案

yes, of course. Apache VFS does exactly this. you can find it under http://commons.apache.org/vfs/. It's a pure java library that can monitor files and it's pretty easy to use:

FileSystemManager manager = VFS.getManager();
FileObject file= manager.resolveFile("c:/MyFile.txt");

DefaultFileMonitor fm = new DefaultFileMonitor(new MyListener());
fm.setDelay(5000);
fm.addFile(file); 
fm.start();

the code above will monitor the file c:/MyFile.txt. if it changes, the object new MyListener() is called.
