Class PathResource
- All Implemented Interfaces:
 InputStreamSource,Resource,WritableResource
Resource implementation for Path handles,
 performing all operations and transformations via the Path API.
 Supports resolution as a File and also as a URL.
 Implements the extended WritableResource interface.
 Note: As of 5.1, Path support is also available
 in FileSystemResource,
 applying Spring's standard String-based path transformations but
 performing all operations via the Files API.
 This PathResource is effectively a pure java.nio.path.Path
 based alternative with different createRelative behavior.

PathResource
Create a new PathResource from a Path handle.Note: Unlike
FileSystemResource, when building relative resources viacreateRelative(java.lang.String), the relative path will be built underneath the given root: e.g. Paths.get("C:/dir1/"), relative path "dir2" → "C:/dir1/dir2"!- Parameters:
 path- a Path handle
 -
