```
public PathResource(Path path)
```
    Create a new PathResource from a Path handle.
    Note: Unlike FileSystemResource, when building relative resources via createRelative(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"!
    参数:
    path - a Path handle
  - PathResource
```
public PathResource(String path)
```
    Create a new PathResource from a Path handle.
    Note: Unlike FileSystemResource, when building relative resources via createRelative(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"!

```
public PathResource(URI uri)
