org.springframework.util.InvalidMimeTypeException: Invalid mime type


Hi Guys ,

This blog is about the error org.springframework.util.InvalidMimeTypeException: Invalid mime type

You may face this error while working with Spring Controllers .

Lets look at the code which caused this error :

return ResponseEntity.ok()
           .contentType( MediaType.valueOf( resp.getFileType() ))




follows 






You can see  a call is made to method valueOf of MediaType . If the value passed in not a valid mime type , we will face this error 



The full stack trace is as follows :





org.springframework.util.InvalidMimeTypeException: Invalid mime type "html": does not contain '/'
