java.io.FileNotFoundException:(Access is denied) at java.io.FileInputStream.open(Native Method) 远程 Tomcat 服务器读取 excel 客户端机器

Question

我正在开发一个 Web 应用程序，它从指定路径读取 excel 文件并将 excel 文件中的数据导入 oracle 数据库。当我在本地 tomcat 机器上运行此功能时，此功能绝对有效，但当我将其部署在远程 tomcat 服务器上时，它会引发以下异常：

java.io.FileNotFoundException: Z:\02_Information_DataBase\ImportingTool\eMan.xls (The     system cannot find the path specified)

远程tomcat服务器对指定文件路径有足够的权限，但即便如此，它仍然说访问被拒绝。

我在互联网上进行了很多冲浪，但徒劳无功....没有任何解决方案可以帮助我。任何人都可以分享有关该问题的信息.....???

Answer 1

Z 听起来像一个映射驱动器。

映射驱动器不适用于作为服务启动的服务器进程，即使它们以用户身份运行。

Use the full qualified UNC-path instead.

*更新： 可以通过进程本身映射驱动器并使用它，但您不应该这样做。
