Get client ip in Jersey 2.22.2

Question

I am trying to acess the clients ip that are calling my rest server but I only get null as a respons. The webserver is running and I can access is from the web browser.

I have tried with

@Context HttpServletRequest

And also with

@Context ContainerRequest request
request.getRequestHeader("HTTP_FORWARDED")
//HTTP_X_FORWARDED
//HTTP_CLIENT_IP

But neither whit sucess, the response is null or blank.

Setup

• Jersey v: 2.22.2
• Grizzly v: 2.3.22
• Java v: 8

Rest.java

   import javax.ws.rs.GET;
   import javax.ws.rs.Path;
   import javax.ws.rs.PathParam;
   import javax.ws.rs.Produces;
   import javax.ws.rs.QueryParam;
   import javax.ws.rs.container.ContainerRequestContext;
   import javax.ws.rs.core.Context;
   import javax.ws.rs.core.MediaType;
   import javax.ws.rs.core.Request;
   import javax.ws.rs.core.UriInfo; 

   @Path("/rest")
   public class Rest {
   @GET
   @Path("/test/")
   @Produces(MediaType.APPLICATION_JSON)
   public TestAddress test(@Context HttpServletRequest re){
      System.out.println(re.getRemoteAddr());
      TestAddress adr = new TestAddress();
      adr.setAge(32);
      adr.setName("Fidde");
      adr.setSurename("Lass");

      //System.out.println(uriInfo.getBaseUri());
      return adr;
   }

main.java

import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.server.ResourceConfig;
import java.io.IOException;
import java.net.URI;

public class Main {
// Base URI the Grizzly HTTP server will listen on
public static final String BASE_URI = "http://localhost:8080/myapp/";

/**
 * Starts Grizzly HTTP server exposing JAX-RS resources defined in this application.
 * @return Grizzly HTTP server.
 */
public static HttpServer startServer() {
    // create a resource config that scans for JAX-RS resources and providers
    // in com.example package
    final ResourceConfig rc = new ResourceConfig().packages("com.example");

    // create and start a new instance of grizzly http server
    // exposing the Jersey application at BASE_URI
    return GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc);
}

/**
 * Main method.
 * @param args
 * @throws IOException
 */
public static void main(String[] args) throws IOException {
    final HttpServer server = startServer();
    System.out.println(String.format("Jersey app started with WADL available at "
            + "%sapplication.wadl\nHit enter to stop it...", BASE_URI));
    System.in.read();
    server.stop();
}

}

Answer 1

HttpServletRequest provides a getRemoteAddr() method that should returns the remote IP address. Note that proxying or NATing may modify the IP address.

EDIT :

The solution is to inject a grizzly request :

@GET
@Path("/test/")
@Produces(MediaType.APPLICATION_JSON)
public TestAddress test(@Context org.glassfish.grizzly.http.server.Request re) {
    System.out.println(re.getRemoteAddr());
    ...
}

This is working for me, but it is totally grizzly dependant.
