@Named

public class PremiumCustomerController {
private static final Logger logger = Logger.getLogger(
PremiumCustomerController.class.getName());
@Inject
@Premium
private Customer customer;
public String saveCustomer() {
PremiumCustomer premiumCustomer =
(PremiumCustomer) customer;
logger.log(Level.INFO, "Saving the following information \n"
+ "{0} {1}, discount code = {2}",
new Object[]{premiumCustomer.getFirstName(),
premiumCustomer.getLastName(),
premiumCustomer.getDiscountCode()});
//If this was a real application, we would have code to save
//customer data to the database here.
return "premium_customer_confirmation";
}
}
Since we used our
@Premium
qualifier to decorate the customer field, an instance
of the
PremiumCustomer
class is injected into that field. This is because this class
is also decorated with the
@Premium
qualifier.
As far as our JSF pages go, we simply access our named bean as usual using its
name, as shown in the following code;
