@Deprecated
public class PathExtensionContentNegotiationStrategy
extends AbstractMappingContentNegotiationStrategy
```
Deprecated.
as of 5.2.4. See class-level note in ContentNegotiationManagerFactoryBean on the deprecation of path extension config options.
A ContentNegotiationStrategy that resolves the file extension in the request path to a key to be used to look up a media type.
If the file extension is not found in the explicit registrations provided to the constructor, the MediaTypeFactory is used as a fallback mechanism.

protected String getMediaTypeKey(NativeWebRequest webRequest)
```
    Deprecated.
    Description copied from class: AbstractMappingContentNegotiationStrategy
    Extract a key from the request to use to look up media types.
    Specified by:
    getMediaTypeKey in class AbstractMappingContentNegotiationStrategy
    Returns:
    the lookup key, or null if none
  - getMediaTypeForResource
```
@Nullable
public MediaType getMediaTypeForResource(Resource resource)
```
    Deprecated.
    A public method exposing the knowledge of the path extension strategy to resolve file extensions to a MediaType in this case for a given Resource. The method first looks up any explicitly registered file extensions first and then falls back on MediaTypeFactory if available.
    Parameters:
    resource - the resource to look up
    Returns:
    the MediaType for the extension, or null if none found
