Inject Anrufer IP-Adresse und Port nicht in Java Jersey RESTful Web-Service arbeiten

Question

Ich versuche, IP-Adresse und Port eines Client zu bekommen, aber wenn ich den Code bereitstellen es gibt mir die folgende Ausgabe:

May 10, 2016 2:50:56 PM com.sun.jersey.spi.inject.Errors processErrorMessages 
SEVERE: The following errors and warnings have been detected with resource and/or provider classes:

Dies ist der Code in meinem REST-Server

import javax.servlet.http.HttpServletRequest; 
import javax.ws.rs.*; 
import javax.ws.rs.core.Context; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 

... 

@POST 
@Path("/post") 
@Consumes(MediaType.TEXT_PLAIN) 
public Response loginUser(String username, @Context HttpServletRequest request) { 
    Loog.i(this, "Login di " + username); 
    String netIP = request.getRemoteAddr(); 
    int netPort = request.getRemotePort(); 
    ... 
} 

Wenn ich @Context HttpServletRequest Anfrage entfernen, funktioniert es einwandfrei.

Answer 1

Sie brauchen nicht die @context in Parameter zu übergeben ..

hier ist meine Schnittstelle:

@POST 
@Path("/lookup") 
@Consumes(MediaType.APPLICATION_JSON) 
@Produces(MediaType.APPLICATION_JSON) 
List<Client> searchClient(Criterias cr); 

hier ist meine Klasse:

@Stateless 
public class XServiceImpl implements XService { 

    @Context 
    private HttpServletRequest request; 

    @Override 
    @Public 
    public List<Client> searchClient(Criterias cr) { 

     try { 
      List<Client> baux = null; 
      String lang = RequestContext.getLocale(request).getLanguage(); 
      cr.setLang(lang); 

     } catch (SQLException e) { 
      LOGGER.log(Level.SEVERE, e.getLocalizedMessage()); 
      throw new ServiceException(); 
     } finally { 
      reqInfo.logExecutionTime(); 
     } 

    } 

Answer 2

Ok ich es herausgefunden:

@Context 
private HttpContext request; 

@POST 
@Consumes(MediaType.TEXT_PLAIN) 
public Response loginUser(String username) { 

    String netIP = request.getRequest().getRequestUri().getHost().toString(); 
    int netPort = request.getRequest().getRequestUri().getPort(); 
    ... 
} 

Die ty pe für das injizierte Objekt war falsch, ich habe com.sun.jersey.api.core.HttpContext; stattdessen.
