Class MultipartPayloadProvider

java.lang.Object
  org.camunda.bpm.engine.rest.mapper.MultipartPayloadProvider

All Implemented Interfaces:

javax.ws.rs.ext.MessageBodyReader<MultipartFormData>

@Provider
public class MultipartPayloadProvider
extends Object
implements javax.ws.rs.ext.MessageBodyReader<MultipartFormData>

Provides a MessageBodyReader for MultipartFormData. This allows writing resources which consume MediaType.MULTIPART_FORM_DATA which is parsed into a MultipartFormData object:

 @POST
 @Consumes(MediaType.MULTIPART_FORM_DATA)
 void handleMultipartPost(MultipartFormData multipartFormData);
 

The implementation used apache commons fileupload in order to parse the request and populate an instance of MultipartFormData.
