Rest - how get IP address of caller

Question

I am writing a Java Rest Web Service and need the caller\'s IP Address. I thought I saw this in the cookie once but now I don\'t see it. Is there a consistent place to get this

Answer 1

Inject a HttpServletRequest into your Rest Service as such:

import javax.servlet.http.HttpServletRequest;

@GET
@Path("/yourservice")
@Produces("text/xml")
public String activate(@Context HttpServletRequest requestContext,@Context SecurityContext context){

   String ipAddressRequestCameFrom = requestContext.getRemoteAddr();

   //Also if security is enabled
   Principal principal = context.getUserPrincipal();
   String userName = principal.getName();

}
