直接已知子类:
AbstractMappingContentNegotiationStrategy
```
public class MappingMediaTypeFileExtensionResolver
extends Object
implements MediaTypeFileExtensionResolver
```
An implementation of MediaTypeFileExtensionResolver that maintains lookups between file extensions and MediaTypes in both directions.
Initially created with a map of file extensions and media types. Subsequently subclasses can use addMapping(java.lang.String, org.springframework.http.MediaType) to add more mappings.
从以下版本开始:
