Jersey Client – Set Cookie Example

In this example, we will learn to set cookies into HTTP requests invoked by Jersey client. This example makes use of Invocation.Builder for setting cookies into outgoing REST calls.

Set Cookie Example

To set a cookie in REST API request, first get reference of Invocation.Builder from webTarget.request() method, and then use it’s methods.

Client client = ClientBuilder.newClient( new ClientConfig().register( LoggingFilter.class ) );
WebTarget webTarget = client.target("http://localhost:8080/JerseyDemos/rest").path("employees");
 
Invocation.Builder invocationBuilder =  webTarget.request(MediaType.APPLICATION_JSON);
Response response = invocationBuilder
							.cookie("cookieParam1","cookieValue1")
							.cookie(new Cookie("cookieParam2", "cookieValue2"))
							.get();
 
Employees employees = response.readEntity(Employees.class);
//More code

Rest API Code

I have written below REST API for testing purpose.

@GET
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Employees getAllEployees(@CookieParam(value="cookieParam1") String cookieParam1,
								@CookieParam(value="cookieParam2") String cookieParam2) 
{
	System.out.println("cookieParam1 is :: "+ cookieParam1);
	System.out.println("cookieParam2 is :: "+ cookieParam2);
	
	Employees list = new Employees();
	list.setEmployeeList(new ArrayList<Employee>());
	
	list.getEmployeeList().add(new Employee(1, "Lokesh Gupta"));
	list.getEmployeeList().add(new Employee(2, "Alex Kolenchiskey"));
	list.getEmployeeList().add(new Employee(3, "David Kameron"));
	
	return list;
}

Demo

Now let’s call above REST API using Jersey client code as suggested in first heading.

public static void main(String[] args) 
{
	Client client = ClientBuilder.newClient( new ClientConfig().register( LoggingFilter.class ) );
	WebTarget webTarget = client.target("http://localhost:8080/JerseyDemos/rest").path("employees");
	 
	Invocation.Builder invocationBuilder =  webTarget.request(MediaType.APPLICATION_JSON);
	Response response = invocationBuilder
								.cookie("cookieParam1","cookieValue1")
								.cookie(new Cookie("cookieParam2", "cookieValue2"))
								.get();
	 
	Employees employees = response.readEntity(Employees.class);
	List<Employee> listOfEmployees = employees.getEmployeeList();
	     
	System.out.println(response.getStatus());
	System.out.println(Arrays.toString( listOfEmployees.toArray(new Employee[listOfEmployees.size()]) ));
}
Output: 

On client side:

Oct 01, 2015 4:53:59 PM org.glassfish.jersey.filter.LoggingFilter log
INFO: 1 * Sending client request on thread main
1 > GET http://localhost:8080/JerseyDemos/rest/employees
1 > Accept: application/json
1 > Cookie: $Version=1;cookieParam1=cookieValue1,$Version=1;cookieParam2=cookieValue2

On server side:

cookieParam1 is :: cookieValue1
cookieParam2 is :: cookieValue2

Happy Learning !!
