How to process a multipart request consisting of a file and a JSON object in Spring restful service?

Question

I have the following resource (implemented using Spring 4.05.RELEASE) which accepts a file and a JSON object:

(P.S. activityTemplate is a serializable entity class)<

Answer 1

You have not given the param names to your @RequestParts ?

public @ResponseBody ActivityTemplate createActivityTemplate(
    @RequestPart("activityTemplate") ActivityTemplate activityTemplate, @RequestPart("file") MultipartFile jarFile)
{
   //process the file and JSON
}

Note: do not forget to include the jackson mapper .jar (maps your Json to ActivityTemplate) file in your classpath.
