我在(v8)中部署了一个webApplication ，它在PC 中运行服务。在这个webApplication中，用户使用表单来上传文件（照片）。我想要的是将这些照片存储在我网络中的磁盘中（服务器和 NAS 磁盘都在同一个网络下）。Tomcat ServerWindows 2008 R2NAS

我阅读并遵循了这个相关的答案。我首先尝试将照片保存在服务器的本地磁盘中，C:并且成功了！

public void saveFiles(List<Part> fileParts,String targetId) { 
        String pathRoot = "C:\\Share\\photos\\;
        String date = new SimpleDateFormat("yyyyMMddHHmmss").format(Calendar.getInstance().getTime());

        try {
            int counter = 1;
            for (Part filePart : fileParts) {

                String destPath = pathRoot + "\\" + targetId;    
                Boolean flag = new File(destPath).mkdirs();                   
                System.err.println("mkdirs flag = " + flag);

                File file = new File(destPath, targetId + " " + date + "-" + counter + ".jpg");

                try (InputStream input = filePart.getInputStream()) {
                    Files.copy(input, file.toPath());
                }

                counter++;
            }
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }

但是，如果我将位置路径更改为NAS磁盘

String pathRoot = "\\\\192.168.0.7\\Share\\photos\\";

然后我收到以下错误：

java.nio.file.FileSystemException: \\192.168.0.7\Share\photos\machines\4 20180704110827-1.jpg: Logon failure: unknown user name or bad password.

您可以通过 2 种方式实现此目的：

1）由于网络驱动器中的“登录”是由Windows完成的，请继续您的服务器（安装并运行tomcat），访问共享文件夹\\192.168.0.7\Share\photos，当它要求提供凭据时，将它们放入并使用复选框记住凭据保存视窗。然后，您可以在控制面板上编辑或删除管理您的网络密码。在这里查看更多信息

2) 你必须使用 Java 的外部库。这里有一个有用的答案

希望能帮助到你

您可以使用Runtime.exec来执行net use \\192.168.0.7\Share\photos your-password /user:your-domain\your-user-name /persistent:yes /savecred. 只需在您的 Web 应用程序初始化期间执行一次。
