Question

我正在尝试在CourseServiceImpl的courseDao字段中添加模拟对象，但它无效。

class FoodMenuTableVC: UITableViewController {

override func viewDidLoad() {
    super.viewDidLoad()

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()

}

// MARK: - Table view data source

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {

    return 1
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    itemList.count + 1

}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    if indexPath.row == 0 {

        let cellIdentifier = "headerCell"

        let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! HeaderCell

        //cell.orderPriceLabel.text = ....?

        return cell

    } else {

        //This works fine

        let cellIdentifier = "itemCell"

        let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! ItemCell

        let name = localSelectedVendorName!


            let keys = Array(itemList.keys)
            let values = Array(itemList.values)

            cell.itemPriceLabel.text = String(values[indexPath.row - 1].price)
            cell.itemOrderCountLabel.text = " "

        }

        return cell
    }

反射语句会抛出一个错误字段＆＃34; courseDao＆＃34;没找到。但是，当我使用new运算符创建一个对象时，它可以正常工作。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(
    locations = {"file:src/main/webapp/WEB-INF/config/servlet-config.xml"}
)
@ActiveProfiles("test")
public final class CourseServiceTest {
  @Mock
  private CourseDao courseDao;
  @Autowired
  private CourseService courseService;
  @Before
  public void setUp() {
    MockitoAnnotations.initMocks(this);
  }

@Test
  public void testCourseServiceNotNull() {
    assertNotNull(courseService);
    assertNotNull(courseDao);
    ReflectionTestUtils.setField(courseService, "courseDao", courseDao, CourseDao.class);
  }

servlet的config.xml中

ReflectionTestUtils.setField(new CourseServiceImpl(), "courseDao", courseDao, CourseDao.class);

请告知。

Answer 1

您的CourseServiceImpl类具有@Transactional注释，这意味着bean实例在"Transational"中作为依赖项注入CourseServiceTest代理，并在Spring上下文中注入所有其他bean。此类代理实例会隐藏原始private实例的所有CourseServiceImpl字段。

因此，您无法访问所需的字段，因为已注入的courseService实例不再是原始CourseServiceImpl类，而是动态cglib或JDK代理类。

ReflectionTestUtils在Spring Test中不能与@Autowired一起使用
