Initially autowired object has value it becomes null after paging using JSF 2 2 and spring 4 01

i'm trying to create basic crud operations using JSF 2.2,Spring 4.01 and Hibernate.

From register.xhtml,if I click register button,it should save firstname(as of now) in the db.

I have
1. registration page(register.xhtml)

2.RegistrationAction(Controller)

3.RegistrationEntity(Entity class which has only one field,firstName, as of now)

4.LoginRegistrationServiceImpl(service class)--I have interface (LoginRegistrationService)

In the controller class(RegistrationAction),when deploying,im getting the service class object,after I clicked the register button,it becomes null.

Below is my code:

RegistrationAction:

@ManagedBean(name="register")
@Controller

public class RegistrationAction implements Serializable{

private RegistrationEntity regEntity=new RegistrationEntity();

private LoginRegistrationService lrInterfcae;

    public LoginRegistrationService getLrInterfcae() {
        return lrInterfcae;
    }

      @Autowired

    public void setLrInterfcae(LoginRegistrationService lrInterfcae) {
        this.lrInterfcae = lrInterfcae;
        System.out.println("Interface Obj--"+lrInterfcae);
    }

    public String registerUser(){

        System.out.println("Interface Obj--"+lrInterfcae);

        return "/login";

    }

    public RegistrationEntity getRegEntity() {
        return regEntity;
    }

    public void setRegEntity(RegistrationEntity regEntity) {
        this.regEntity = regEntity;
    }

}

SERVICE CLASS-LOGINREGISTRATIONSERIMPL

@Service

public class LoginRegistrationSerImpl implements LoginRegistrationService{
    }

inputText:firstname

commandbutton:Register,in action attribute I called registerUser method of RegistrationAction class.
