Unit test for spring controller

This is my controller class

@Controller
public class MySpringController {

    @Resource(name="myLogic")
    private MyService myService;

    @RequestMapping(value = "/employees", method = RequestMethod.GET)
    public String getPersons(Model model) {
        List<MyHibernateJPA> employeesEspn = myService.getAll();
        model.addAttribute("employeesEspn", employeesEspn);
        return "myFormPage";
    }

    @RequestMapping(value = "/employees/add", method = RequestMethod.GET)
    public String add(ModelMap model){
        MyHibernateJPA espn = new MyHibernateJPA();
        model.addAttribute("espn", espn);
        return "addemployee";
    }


    @RequestMapping(value = "/employees/add", method = RequestMethod.POST)
    public String addPost(ModelMap model, @ModelAttribute("espn") MyHibernateJPA passedValues){
        myService.add(passedValues.getSname(), passedValues.getScourse());
        return "redirect:/employees";
    } 
}

This is my service class
package org.test.service;

@Service("myLogic")
@Transactional
public class MyService {

    @Autowired
    private SessionFactory sessionFactory;
    public List<MyHibernateJPA> getAll() {
        Session session = sessionFactory.getCurrentSession();
        Query query = session.createQuery("FROM  MyHibernateJPA");
        return  query.list();
    }
    public void add(String sname, String scourse) {

        Session session = sessionFactory.getCurrentSession();

        MyHibernateJPA employee = new MyHibernateJPA();
        employee.setSname(sname);
        employee.setScourse(scourse);
        session.save(employee);
    }
}

In my model class i have just created entities. I am trying to write the unit test for my controller

        @Test
        public void getAll_ShouldAddTodoEntriesToModelAndRenderTodoListView() throws Exception {
            MyHibernateJPA first = new MyHibernateJPA()
                   .sno(1)
                    .sname("Lorem ipsum")
                    .scourse("Foo");

            MyHibernateJPA second = new MyHibernateJPA()
                    .sno(2L)
                    .sname("Lorem ipsum")
                    .scourse("Bar")
                    .build();

           when(todoServiceMock.getAll()).thenReturn(Arrays.asList(first, second));

However I think that this is not the correct way as i am seeing errors. How to pass the value for sno, sname and scourse so that i can check it?
