serveFile

@GetMapping("/{className}/{fieldName}/{id}")
@ResponseBody
public org.springframework.http.ResponseEntity<byte[]> serveFile(@PathVariable
 String className,
 @PathVariable
 String fieldName,

This tries to detect the file type using Tika in order to serve the file with a plausible extension, since we don't have any meta-data about what was originally uploaded and it is not feasible to store it (it could be modified on another end and we wouldn't be aware of it).

Parameters:

className -

fieldName -

id -

Returns:
