Spring MultipartFile validation and conversion

Question

I currently have a Spring MVC controller that takes a MultipartFile

@RequestMapping(method = RequestMethod.POST)
public String doUpload(@RequestParam(\"file         


        

Answer 1

You need a converter that is able to convert a MultipartFile into MyObjects, but not to convert String[] to MyObjectsContainer. - MyObjectsContainer is nothing more than a wrapper around the list of MyObjects.

But I really don't know if this converter will work, because MultipartFile is some very special parameter.

For Validation I strongly recommend JSR 303 Bean Validation annotations at MyObjectsContainer

Then you can write:

@RequestMapping(method = RequestMethod.POST)
public String doUpload(@RequestParam("file") final MyObjectsContainer container) {}
