Spring MVC release 4.2.6 seems does not inject mock service into the controller when testing controller method - spring

Question

I really searched and followed the steps of creating a unit test class for spring MVC controller, however unit test is running with a green pass flag but the framework uses the original service class and it calls to the database. I mocked the class and used #InjectMocks together with MockitoAnnotations.initMocks(this). Still when the test runs, the controller uses original service object rather than the mocked object. I really appreciate if somebody can help me in this regards.
Here is UserManager(service class), UserRegisterController(controller), TestUserRegisterController (Test class) classes with a picture of the Eclipse package structure
Service :
#Service
public class UserManager {
protected Map<String, String> getAllCertificates() {
Map<String, String> allCertificates = new HashMap<String, String>();
//call to database
return allCertificates;
}
protected User getUser(int userId) {
//create session
User user = session.get(User.class, userId);
//close session
return user;
}
}
Controller :
#Controller
public class UserRegisterController {
#Autowired
private UserManager manager;
#InitBinder
public void initBinder(WebDataBinder binder) {
//do some work
}
#RequestMapping(value = "/user.html", method = RequestMethod.GET)
public ModelAndView getUser(#RequestParam(value="userId", defaultValue="-1") String userId) {
User user1;
user1 = this.manager.getUser(Integer.parseInt(userId));
if (user1 == null) {
user1 = new User();
}
ModelAndView view = new ModelAndView("User", "user1", user1);
view.addObject("allCertificatesMap", this.manager.getAllCertificates());
return view;
}
#ModelAttribute
public void setModelAttribute(Model model) {
model.addAttribute("PageHeader", "lable.pageHeader");
}
}
Test class :
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration("test-spring-dispatcher-servlet.xml")
#WebAppConfiguration
public class TestUserRegisterController {
#Mock
private UserManager userManager;
#InjectMocks
private UserRegisterController userRegisterController;
#Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
#Before
public void setUp() throws Exception {
// Process mock annotations
MockitoAnnotations.initMocks(this);
User user2 = new User();
user2.setUserId(10006);
user2.setUserName("Reza");
user2.setHobby("Quadcopter");
user2.setPhone("4032376295");
when(this.userManager.getUser(10006)).thenReturn(user2);
when(this.userManager.getAllCertificates()).thenReturn(new HashMap<String, String>());
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}
#Test
public void getUser() {
try {
this.mockMvc.perform(get("/user.html").param("userId", "10006"))
.andExpect(status().isOk())
.andExpect(forwardedUrl("/WEB-INF/jsp/User.jsp"))
.andExpect(MockMvcResultMatchers.view().name("User"))
.andExpect(model().attributeExists("allCertificatesMap"));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

Use #RunWith(MockitoJUnitRunner.class) to get the #InjectMocks and other annotations to work
