I am not able to mock the Dao method using mockito in Spring boot application

I am not able to mock Dao method in spring boot. Please let me know what I am doing wrong in below code. I tried using SpringJUnit4ClassRunner and mock the Dao method. But still, it's going into the Dao method instead of returning the mock value. I also tried with MockitoJUnitRunner but that time not able to call the service method as its getting null value.

@RestController
public class HomeController {

    @Autowired
    HomeSeriveInterface service;

    @Autowired
    HomeDaoImpl homeDao;

    @GetMapping(value="/getData")
    public String Data() {
        System.out.println("Inside Controller");
        List < Map < String, Object >> rows = service.getData();
        return "Hi Yogita" + rows;
    }

}

@Service
public class HomeService implements HomeSeriveInterface{

    @Autowired
    HomeDao dao;

    @Override
    public List<Map<String, Object>> getData() {
        System.out.println("Inside Service");
        return dao.getData();
    }

}

@Repository
public class HomeDaoImpl implements HomeDao{

    @Autowired
     @Qualifier("jdbcTemplate1")
     private JdbcTemplate jdbcTemplate;

    @Override
    public List < Map < String, Object >> getData() {
        System.out.println("Inside Dao");
        List < Map < String, Object >> rows = jdbcTemplate.queryForList("SELECT * FROM COURCES");
        return rows;
    }

}

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class CcdWebApplicationTests {


    @InjectMocks
    @Autowired
    HomeController homeController;

    @Mock
    HomeDao homeDao;

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

    @Test
    public void getDataTest() {
        System.out.println("testing *******");
        List < Map < String, Object >> data = null;
        Mockito.when(homeDao.getData())
        .thenReturn(data);
        System.out.println("2nd *");
        String data2 = homeController.Data();
        System.out.println(data2);

    }

}

You don't need @InjectMocks and use @MockBean instead of @Mock:

@Autowired
HomeController homeController;

@MockBean
HomeDao homeDao;

You also do not need this part:

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