Working with Cookies
Problem
You want your JAX-RS service to set and accept an HTTP cookie.
Solution
Use the @CookieParam annotation on your method parameters.
Discussion
All of the parameter types in JAX-RS work by injection. You can simply add a parameter
to your business method that is of the appropriate type ( HeaderParam , CookieParam ,
FormParam , etc.), and the runtime will inject the value so you can work with it locally.
Example 8-29 demonstrates the setting and reading of a cookie.
Example8-29.CookieService.java
package com.soacookbook.rest.cookie;
import javax.ws.rs.CookieParam;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Cookie;
import javax.ws.rs.core.NewCookie;
import javax.ws.rs.core.Response;
@Path("/cookie")
@Produces("text/html")
public class CookieService {
//set cookie on home page
@GET
@Path("/home")
public Response home() {
System.out.println("Home page.");
//create a cookie object
NewCookie cookie = new NewCookie("MY_KEY", "MY_VALUE");
