Jersey restful web service - File upload with multiple object

Question

I'm new to web service and I'm developing a document management system and trying to save the file and multiple object using Jersey restful web service.

import java.awt.Image;
import java.io.InputStream;
import java.util.List;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import com.sasianet.dmsservice.data.dao.UserDocumentDao; 
import com.sasianet.dmsservice.data.entity.UserDocument; 
import com.sasianet.dmsservice.data.entity.UserDocumentAttachment;
import com.sun.jersey.core.header.FormDataContentDisposition;
import com.sun.jersey.multipart.FormDataParam;

@Path("/userDocument")
public class UserDocumentService {

    @GET 
    @Produces(MediaType.APPLICATION_JSON)
    public List<UserDocument> findAll(){
        List<UserDocument> userDocuments = null;
        try{ 
            UserDocumentDao udo = new UserDocumentDao();
            userDocuments = udo.findAll(); 
        }catch(Exception e){
            e.printStackTrace();
        }
        return userDocuments;
    }

    @POST
    @Path("/post/test")
    @Consumes({MediaType.MULTIPART_FORM_DATA})
    public Response uploadFileWithData(
            @FormDataParam("file") InputStream fileInputStream,
            @FormDataParam("file") FormDataContentDisposition cdh,
            @FormDataParam("userDoc") UserDocument userDocument,
            @FormDataParam("attachment") UserDocumentAttachment userDocumentAttachment) throws Exception{

        Image img = ImageIO.read(fileInputStream);
        JOptionPane.showMessageDialog(null, new JLabel(new ImageIcon(img)));
        System.out.println(cdh.getName());
        System.out.println(userDocument.getDescription());
        System.out.println(userDocumentAttachment.getAttachmentName());

        return Response.ok("Cool Tools!").build();
    }   
}

My web.xml

    </context-param> 

</web-app>

Once run this service, I faced the following error

org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.
[[FATAL] No injection source found for a parameter of type public javax.ws.rs.core.Response com.sasianet.dmsservice.service.UserDocumentService.uploadFileWithData(java.io.InputStream,com.sun.jersey.core.header.FormDataContentDisposition,com.sasianet.dmsservice.data.entity.UserDocument) throws java.lang.Exception at index 0.; source='ResourceMethod{httpMethod=POST, consumedTypes=[multipart/form-data], producedTypes=[], suspended=false, suspendTimeout=0, suspendTimeoutUnit=MILLISECONDS, invocable=Invocable{handler=ClassBasedMethodHandler{handlerClass=class com.sasianet.dmsservice.service.UserDocumentService, handlerConstructors=[org.glassfish.jersey.server.model.HandlerConstructor@53d69bbb]}, definitionMethod=public javax.ws.rs.core.Response com.sasianet.dmsservice.service.UserDocumentService.uploadFileWithData(java.io.InputStream,com.sun.jersey.core.header.FormDataContentDisposition,com.sasianet.dmsservice.data.entity.UserDocument) throws java.lang.Exception, parameters=[Parameter [type=class java.io.InputStream, source=file, defaultValue=null], Parameter [type=class com.sun.jersey.core.header.FormDataContentDisposition, source=file, defaultValue=null], Parameter [type=class com.sasianet.dmsservice.data.entity.UserDocument, source=emp, defaultValue=null]], responseType=class javax.ws.rs.core.Response}, nameBindings=[]}', [WARNING] A resource, Resource{"/file", 0 child resources, 0 resource methods, 0 sub-resource locator, 0 method handler classes, 0 method handler instances}, with path "/file" is empty. It has no resource (or sub resource) methods neither sub resource locators defined.; source='Resource{"/file", 0 child resources, 0 resource methods, 0 sub-resource locator, 0 method handler classes, 0 method handler instances}']

Project libraries are

So, I cant find any solution to this and is there any different way to upload file with multiple object with one rest call.

Please guide me on this.

Answer 1

1. You're using the wrong version multipart dependency. Anytime you see com.sun.jersey in the package, that is for Jersey 1.x, and you should not use it for a 2.x project. You will need to switch versions and then register the MultiPartFeature. For more information, see MULTIPART_FORM_DATA: No injection source found for a parameter of type public javax.ws.rs.core.Response

2. Unless the client is able to set the Content-Type for each body part (some clients can't), you will need to tweak the method a little bit, in order to get the result an object. For example

   public Response post(@FormDataParam("doc") FormDataBodyPart docpart) {
       docpart.setMediaType(MediaType.APPLICATION_JSON_TYPE);
       UserDocument doc = docpart.getValueAs(UserDocument.class);
   }
   

   For the InputStream parameter, you don't need to do this. For more detail, see File upload along with other object in Jersey restful web service
