MockMvc response returns 404, expected response 201 - spring-boot

Question

I am new to unit testing REST API in Spring Boot.
I am expecting response status as CREATED but instead I am getting a PAGE NOT FOUND error.
Below is the code for:-
UserControllerUnitTests
#SpringBootTest
#ContextConfiguration(classes = { CommonConfig.class, SecurityConfig.class})
#RunWith(SpringRunner.class)
class UserControllerUnitTests {
private static ObjectMapper mapper;
private static final String URI = "/users";
MockMvc mvc;
#Autowired
WebApplicationContext webAppContext;
#Mock
UserService userService;
MvcResult mvcResult;
#BeforeAll
static void setUp() {
mapper = new ObjectMapper();
}
#BeforeEach
void initialize() throws Exception {
mvc = MockMvcBuilders.webAppContextSetup(webAppContext).build();
....
....
....
void shouldReturnStatusCreatedIfValidUserPassedForPostUser(long index) throws Exception {
int expectedStatus = HttpStatus.CREATED.value();
UserDAO returnUser;
UserDAO user = userList.get(index);
userList.remove(index);
String jsonContent = mapper.writeValueAsString(user);
user.setId(index);
user.setEncryptedPassword(null);
Mockito.when(userService.addUser(Mockito.any())).thenReturn(user);
mvcResult = mvc.perform(MockMvcRequestBuilders.post(URI)
.accept(MediaType.APPLICATION_JSON)
.contentType(MediaType.APPLICATION_JSON)
.content(jsonContent)).andReturn();
//Mockito.verify(userService, Mockito.times(1)).addUser(Mockito.any());
int actualStatus = mvcResult.getResponse().getStatus();
Assert.assertEquals("Response status should be CREATED", expectedStatus, actualStatus);
jsonContent = mvcResult.getResponse().getContentAsString();
returnUser = mapper.readValue(jsonContent, UserDAO.class);
Assert.assertEquals("EncryptedPassword should not be returned", null,
returnUser.getEncryptedPassword());
}
User Controller.class
#RestController
#RequestMapping("users/")
public class UserController {
UserService userService;
#Autowired
public UserController(UserService userService) {
this.userService = userService;
}
....
....
....
#PostMapping(path = "",
consumes = { MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON },
produces = { MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public ResponseEntity<UserDAO> createUser(#Valid #RequestBody UserDAO user) {
String password = user.getEncryptedPassword();
user.setEncryptedPassword(null);
UserDAO retreivedUser;
if(user.getId() != 0)
return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
user.setEncryptedPassword(password);
retreivedUser = userService.addUser(user);
if(retreivedUser != null)
return new ResponseEntity<>(retreivedUser, HttpStatus.CREATED);
return new ResponseEntity<>(HttpStatus.CONFLICT);
}
}

I spotted a few errors:
Get rid of ContextConfiguration
#SpringBootTest
// #ContextConfiguration(classes = { CommonConfig.class, SecurityConfig.class})
#RunWith(SpringRunner.class)
class UserControllerUnitTests {
Specify correct mapping on the controller (no slash)
#RestController
#RequestMapping("users")
public class UserController {
You setup your UserService mock which is not used in the test. Did you mean #MockBean?
#MockBean
UserService userService;
