Jersey 2 injection source for multipart formdata

Question

I had a method:

@POST
@Consumes(\"multipart/form-data\")
@Produces( {\"text/xml\"})
public Response processForm(
    @FormDataParam(\"myparam\") InputStream          


        

Answer 1

You need to enable MultiPart feature on your application. Enabling this feature injects necessary message body readers, writers to your Jersey 2 application. Here is how you register them:

On the server-side (http-server):

final ResourceConfig resourceConfig = new ResourceConfig(MultiPartResource.class);
resourceConfig.register(MultiPartFeature.class);

On the server-side (servlet deployment):

import org.glassfish.jersey.filter.LoggingFilter;
import org.glassfish.jersey.media.multipart.MultiPartFeature;

import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;

public class MyApplication extends Application {
    @Override
    public Set> getClasses() {
        final Set> classes = new HashSet>();
        // register resources and features
        classes.add(MultiPartFeature.class);
        classes.add(MultiPartResource.class);
        classes.add(LoggingFilter.class);
        return classes;
    }
}

web.xml

    
    
        Jersey Servlet
        org.glassfish.jersey.servlet.ServletContainer
        
            javax.ws.rs.Application
            com.aruld.jersey.multipart.MyApplication
        
        1
    
    
        Jersey Servlet
        /*
    

On the client-side:

final ClientConfig clientConfig = new ClientConfig();
clientConfig.register(MultiPartFeature.class);
Client client = ClientFactory.newClient(clientConfig);

I put together an end-to-end Jersey 2 MultiPart sample in Github here.
