Windows：使用File.listRoots显示映射的网络驱动器 [英] Windows: Display mapped network drives with File.listRoots

问题描述

代码：

  import java.io. *; 
 
 public class TestFileRoots {
 
 public static void main（String [] args）{
 for（File f：File.listRoots（））{
 System.out.println（f.getAbsolutePath（））; 
 
 
 
 $ b  

当我启动cmd并运行这个类，我所有的驱动器都列出来了。当我以管理员身份启动cmd并运行此操作时，映射的网络驱动器未列出。

另外，当我手动启动服务器并调用File.listRoots ，我所有的驱动器都列出来了。但是，当我使用服务启动服务器时，网络驱动器未列出。

如何始终列出我的网络驱动器？我读了我可以映射在一个服务的网络驱动器，但这不是一个选项。驱动器已经在那里，我不能改变它的一些东西。

解决方案

映射的驱动器是用户特定的在登录期间）而不是计算机特定的。因此，驱动器上的 userA 日志被映射。当您以不同的用户身份启动程序（即以管理员身份或以SYSTEM身份运行的服务）时，映射的驱动器不可用，因此您无法访问它们。您的选项是：

$ ul

将驱动器重新映射为新用户（即服务）

运行您的应用程序在当前用户的上下文中

通过UNC路径访问您需要的文件（而不是 s：\blah use \\server\shared_folder\blah

Code:

import java.io.*;

public class TestFileRoots {

    public static void main(String[] args) {
        for(File f : File.listRoots()){
            System.out.println(f.getAbsolutePath());
        }
   }

}

When I start cmd and run this class, all of my drives are listed. When I start cmd as an administrator and I run this, my mapped network drives are not listed.

Also, when I start my server manually and call File.listRoots(), all of my drives are listed. But when I start the server using a service, the network drives are not listed.

How can I always list my network drives? I read I can map the network drive within a service, but that's not an option. The drives are already there and I am not permitted to change something about it.

解决方案

Mapped drives are user-specific (probably mapped during log-on) and not computer specific. So, when userA logs on the drives are mapped. When you start your program as a different user (i.e. as administrator or as a service running as SYSTEM) the mapped drives are not available so you can't access them. Your options are:

• Map the drives again as the new user (i.e. service)
• Run your application in the current user's context
• Access the files you need by the UNC path (i.e. instead of s:\blah use \\server\shared_folder\blah
