How to inject a network file resource with Spring?

How can I tell Spring that the resource is supposed to be a network resource, and let it autowire accordingly?

@Value("\\MY-MACHINE\thefile.txt")
private Resource file;

Result:

Caused by: java.io.FileNotFoundException: class path resource [MY-MACHINE\thefile.txt] cannot be resolved to URL because it does not exist

As nobody seems to be aware of, I found out that it's just necessairy to use double slashes like:

@Value("\\\\MY-MACHINE\\thefile.txt")
private Resource file;

In some cases you may required a file: statement before, like: file:\\\\MY-MACHINE\\thefile.txt"

I am assuming your application is deployed on Windows. I don't have anywhere windows workstation to test it, but as far as I remember this is how it goes:

  • create symbolic link to your network location:

    mklink /D C:\my-machine \\MY-MACHINE\

  • refer to this symlink with absolute path:

@Value("file:///C:/my-machine/thefile.txt")
private Resource file;

Accessing a file on a Windows share will not work directly. See connecting to shared folder in windows with java for more info on how to do that.

This is the easiest way using classpath

import org.springframework.core.io.Resource;

@Value("classpath:<path to file>")
private Resource file;
