404 not found while testing spring boot rest api

I am trying to write tests on my applicatoin's rest api. I am using spring boot, jersey rest. For testing I am trying to use MockMvc, but for all GET requests I get 404 status code. I tried different ways to run it, but result is always the same. I think I am missing something, so, please, advise.

REST resource:

@Component
@Path("/v1/users")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@Transactional(readOnly = true)
public class UserResource {
    private final UserService userService;

    @Inject
    public UserResource(UserService userService) {
        this.userService = userService;
    }

    @GET
    public Collection<User> list() {
        return userService.fetchAllUsers();
    }
}

Application class:

@SpringBootApplication
@ComponentScan("com.glasierr.application")
@EnableJpaRepositories("com.glasierr.application.infrastructure.persistence.spring")
public class UserServiceApplication {
    public static void main(String[] args) {
        new SpringApplicationBuilder()
                .sources(UserServiceApplication.class)
                .run(args);
    }
}

Jersey config:

@Configuration
@ApplicationPath("/api")
public class JerseyConfig extends ResourceConfig {
    public JerseyConfig() {
        packages("com.glasierr.application.resource");
    }
}

Test properties snippet:

server:
  port: 9999

database:
  driverName: org.h2.Driver
  url: jdbc:h2:mem:test;IGNORECASE=TRUE;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1

Testing class:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(UserServiceApplication.class)
@WebIntegrationTest
public class UserResourceTest {

    @InjectMocks
    private UserResource userResource;

    @Mock
    private UserService userService;

    @Autowired
    private WebApplicationContext context;

    private MockMvc mvc;

    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);

        mvc = MockMvcBuilders
                .webAppContextSetup(context)
                .build();
    }

    @Test
    public void test() throws Exception {
        when(userService.fetchAllUsers()).thenReturn(Arrays.asList(new User("user1"), new User("user2")));

        mvc.perform(get("/api/v1/users").accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
                .andExpect(status().isOk());
    }
}
