How To Maintain Cookies Using CXF

How To Maintain Cookies Using CXF explains about Maintaining Cookies Using CXF

I am showing here, How to do maintain Cookies in CXF framework, this is applicable for both SOAP & RESTFul services

Message message = PhaseInterceptorChain.getCurrentMessage();
HttpServletRequest request = (HttpServletRequest)message.get(AbstractHTTPDestination.HTTP_REQUEST);
Cookie[] cookies = request.getCookies();

On this code, we are getting HttpServletRequest and from that we are getting cookies object in CXF

You can see the below example, on which we are storing a value into cookies from client side and retrieving the same, using CXF Framework

Note

This tutorial is also applicable for JAX-WS Web services because PhaseInterceptorChain.getCurrentMessage() applicable for both JAX-WS and JAX-RS based services

You can change CXF Web Service Tutorial according to the below tutorial, if you are using JAX-WS based service

You can also rely on HttpConduit and you will get cookies from HttpConduit, then append before the next call

Enable Cookies Using CXF

I am going to re-use CXF Restful Tutorial

We are making changes ChangeStudentDetailsImpl class, just adding

PhaseInterceptorChain.getCurrentMessage() and getting HttpServletRequest, so that we can access Cookie object in CXF Framework

package com.student;

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

import org.apache.cxf.message.Message;
import org.apache.cxf.phase.PhaseInterceptorChain;
import org.apache.cxf.transport.http.AbstractHTTPDestination;

// Maintain Cookies Using CXF

@Consumes("application/json")
@Produces("application/json")
public class ChangeStudentDetailsImpl implements ChangeStudentDetails {

@POST
@Path("/changeName")
public Student changeName(Student student) {
    // Here We are getting cookies from HttpServletRequest
    Message message = PhaseInterceptorChain.getCurrentMessage();
    HttpServletRequest request = (HttpServletRequest) message.get(AbstractHTTPDestination.HTTP_REQUEST);
    Cookie[] cookies = request.getCookies();
    if (cookies != null) {
      for (Cookie cookie : cookies) {
        student.setName("HELLO " + cookie.getValue());
      }
    }
    return student;
}

@GET
@Path("/getName")
public Student getName() {
    Student student = new Student();
    student.setName("Rockey");
    return student;
}
}

Run Client

package com.client;

import java.io.IOException;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Scanner;

// Cookie Handling Using CXF

public class PostStudentClient {

public static void main(String[] args) {
    try {
      URL url = new URL("http://localhost:8080/CXFRestfulTutorial/rest/changeName");
      HttpURLConnection conn = (HttpURLConnection) url.openConnection();
      conn.setDoOutput(true);
      conn.setRequestMethod("POST");
      conn.setRequestProperty("Content-Type", "application/json");
      conn.setRequestProperty("Cookie", "name=Tom");

      String input = "{\"Student\":{\"name\":\"Tom\"}}";

      OutputStream os = conn.getOutputStream();
      os.write(input.getBytes());
      os.flush();

      Scanner scanner;
      String response;
      if (conn.getResponseCode() != 200) {
        scanner = new Scanner(conn.getErrorStream());
        response = "Error From Server \n\n";
      } else {
        scanner = new Scanner(conn.getInputStream());
        response = "Response From Server \n\n";
      }
      scanner.useDelimiter("\\Z");
      System.out.println(response + scanner.next());
      scanner.close();
      conn.disconnect();
    } catch (MalformedURLException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
}
}

Output

Response From Server 

{"Student":{"name":"HELLO Tom"}}
