@Documented @Retention(value=RUNTIME) @Target(value={METHOD,FIELD}) public @interface FileSystemResource
Here is how injection would typically happen:
 public class MySecondaryFS implements IgfsSecondaryFileSystem {
      ...
      // Inject instance of primary filesystem.
      @FileSystemResource
      private IgniteFileSystem igfs;
      ...
  }
 
 or attach the same annotations to methods:
 
 public class MySecondaryFS implements IgfsSecondaryFileSystem {
     ...
     private IgniteFileSystem igfs;
     ...
      // Inject instance of primary filesystem.
      @FileSystemResource
     public void setIgfs(IgniteFileSystem igfs) {
          this.igfs = igfs;
     }
     ...
 }
