如何使用Java代碼

Question

public class Upload extends HttpServlet 
{ 

     private static final long serialVersionUID = 1L; 
     public void init() throws ServletException 
     { 

       System.out.println(this.getClass().getName()); 
     } 

     protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
     { 
       //boolean MultipartRequest; 
     //String PrintWriter; 

       response.setContentType("text/html"); 

       PrintWriter out=response.getWriter(); 
       MultipartRequest multipartRequest = new MultipartRequest(request,"/home/hadoop/Desktop"); 

       out.println("succcesfully uploaded"); 

     } 
     public void destroy() 
     { 
       System.out.println(this.getClass().getName()); 
     } 

} 

• 什麼，我需要做的移動uploded到桌面文件夾 直接，而不是直接給文件名，如下
• 和一個要移動的文件上傳文件到歸檔文件夾更多的是如何複製重複太...

public class MoveFile { 

    public static void main(String[] args) throws IOException { 

     File sourceFile = new File("/home/hadoop/Desktop/LINUX-KACPER.pdf"); 
     File destinationDir = new File("/home/hadoop/Documents/movedfiles/"); 

     FileUtils.moveFileToDirectory(sourceFile, destinationDir, true); 

    } 

Answer 1

這是移動文件，timemill ....

public class Moveall { 
public static void main(String[] args) throws IOException { 
    File destinationDir = new File("/home/hadoop/Documents/movedfiles/"); 
    File directory = new File("/home/hadoop/Desktop/"); 
    File[] subfiles = directory.listFiles(); 
    for(File f:subfiles){ 
    FileUtils.moveFile(f,new File(destinationDir.getPath()+"/"+System.currentTimeMillis()+f.getName())); 
    System.out.println("moved succesfully...."); 

    } 
} 

}

Answer 2

我不知道，這是答案：

public class MoveFile { 
    public static void main(String[] args) throws IOException { 
     File destinationDir = new File("/home/hadoop/Documents/movedfiles/"); 
     File directrory = new File("/home/hadoop/Desktop/"); 
     File[] subfiles = directory.listFiles(); 
     for(File f:subfiles){ 
      new File(destinationDir.getAbsolutePath()+f.getName()).delete() //remove the duplicate 
      FileUtils.moveFileToDirectory(f, destinationDir, true); 
     } 
    } 
} 

該代碼將選擇在桌面上的所有文件，並將其移動到movedfiles 可以使用的FileFilter作爲listFiles http://docs.oracle.com/javase/7/docs/api/java/io/File.html#listFiles(java.io.FileFilter)

編輯的參數（版本）：

public class MoveFile { 
    public static void main(String[] args) throws IOException { 
     File destinationDir = new File("/home/hadoop/Documents/movedfiles/"); 
     File directrory = new File("/home/hadoop/Desktop/"); 
     File[] subfiles = directory.listFiles(); 
     for(File f:subfiles){ 
      File previous = new File(destinationDir.getAbsolutePath()+f.getName()) 
      if(!previous.exists()){ 
       FileUtils.moveFileToDirectory(f, destinationDir, true); 
      }else{ 
       FileUtils.moveFile(f,new File(destinationDir.getAbsolutePath()+"_"+System.currentTimeMillis()+f.getName()), true); 
      } 
     } 
    } 
}

方法
http://docs.oracle.com/javase/7/docs/api/java/lang/System.html#currentTimeMillis()
的第一件事是如何讓一個版本，當然也可以用
http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html#getInstance()
解決但這僅僅是簡單的例子
