Java spring/jsf控制器的JUnit测试-数据重置

我遇到了以下问题。我有一个带有模型的控制器，其中包含一些字段、列表等。现在我有了一个

@Before

方法，在这里我初始化了一些测试数据。不幸的是，每次调用，例如

model.getList（）.add（element）

这个列表都有新的引用，并且会再次创建，我的数据丢失。我可以调试到

add

方法中，并检查它是否正确地添加了它，然后当调用next

add

时，列表具有新的引用并且为空。由于这个问题，当涉及到

@Test

方法时，它们应该调用一些控制器方法并对以前添加的数据执行操作，但没有。我的控制器和模型的作用域是

@Scope（value=“view”，proxyMode=ScopedProxyMode.TARGET\u CLASS）

。当我将其更改为

@SessionScope

时，它工作正常，但由于应用程序的要求，我不得不将范围切换到

视图。你能帮我解决这个问题吗？也许是其他的测试方法或者其他的想法

这是我的控制器类：

@Controller
@Scope(value = "view", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class BaseController extends AbstractController<BaseModel> {
    //some logic 
}

模型类：

@Repository
@Scope(value = "view", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class BaseModel extends AbstractModel {

  @PostConstruct
  public void init() {
      //initialization stuff
  }

//data logic methods

}

最后是我的测试课：

@RunWith(SpringRunner.class)
@WebAppConfiguration
@SpringBootTest(classes = Application.class)
@AutoConfigureTestDatabase
public class BaseControllerTest {

@Autowired
private WebApplicationContext context;

@Autowired
private BaseController controller;

@Autowired
private BaseModel model;

@Autowired
private LoggingDao loggingDao;

private MockMvc mvc;

private UsbDeviceDBO usbDeviceDBO1;
private UsbDeviceDBO usbDeviceDBO2;
private UsbDeviceDBO usbDeviceDBO3;
private UsbDeviceDBO usbDeviceDBO4;
private UsbDeviceDBO usbDeviceDBO5;
private UsbDeviceDBO usbDeviceDBO6;

@Before
public void before() {
    mvc = MockMvcBuilders.webAppContextSetup(context).apply(springSecurity()).build();

    FacesContext context = ContextMocker.mockFacesContext();
    UIViewRoot uiViewRoot = Mockito.mock(UIViewRoot.class);
    Mockito.when(context.getCurrentInstance().getViewRoot())
            .thenReturn(uiViewRoot);
    Mockito.when(
            context.getCurrentInstance().getViewRoot().getLocale())
            .thenReturn(new Locale("en"));
}

public void insertTestData() {
    usbDeviceDBO1 = new UsbDeviceDBO("device1", EDeviceUsageMode.ALWAYS, "Custom", "comment1");
    usbDeviceDBO2 = new UsbDeviceDBO("device2", EDeviceUsageMode.INSTALL, "Custom", "comment2");
    usbDeviceDBO3 = new UsbDeviceDBO("device3", EDeviceUsageMode.ALWAYS, "Custom", "comment3");
    usbDeviceDBO4 = new UsbDeviceDBO("USB\\class_01", EDeviceUsageMode.ALWAYS, "Class 01: Audio", "comment4");
    usbDeviceDBO5 = new UsbDeviceDBO("USB\\VID_05BA&PID_000A", EDeviceUsageMode.ALWAYS, "[Diebold] (Digital Persona, Inc) Biometric Reader", "comment5");
    usbDeviceDBO6 = new UsbDeviceDBO("USB\\VID_0596&PID_0001", EDeviceUsageMode.ALWAYS, "[Wincor Nixdorf] 3M Touch Controller", "comment5");

    model.getUsbDeviceTable().add(usbDeviceDBO1);
    model.getUsbDeviceTable().add(usbDeviceDBO2);
    model.getUsbDeviceTable().add(usbDeviceDBO3);
    model.getUsbDeviceTable().add(usbDeviceDBO4);
    model.getUsbDeviceTable().add(usbDeviceDBO5);
    model.getUsbDeviceTable().add(usbDeviceDBO6);

    model.getUsbDeviceTable().clearSelection();
}

@Test
public void updateUsedDeviceIdsTest() {
    insertTestData();
    UsbDeviceDBO clonedDevice = new UsbDeviceDBO("device1", EDeviceUsageMode.ALWAYS, "Custom", "comment1");
    controller.updateUsedDeviceIds(clonedDevice);

    assertEquals(5, model.getUsedDeviceIds().size());
}

每次涉及到
updateUsedDeviceTest
方法时，断言都会失败，但应该有5个元素，但当添加测试数据时，在每次调用
model.getUsbDeviceTable（）.add（usbDeviceDBO1）之后我获得了对包含数据的列表的新引用。因此，当我的
controller.updateUserDeviceID（clonedDevice）时开始，列表有0个元素。在我的模型中，同样的情况也发生在常规对象上，而不是集合上。任何帮助都将不胜感激

我使用的是SpringBoot 2.0.2+PrimeFaces 6.2，运行在IntelliJ IDE、JSF 3.2.1版、JUnit 4.12上。
clearSelection（）
方法在做什么？
table.getSelectedList（）.clear（）
-它只是清除当前选择的表，即数据添加到的不同列表。没有范围，例如spring上的视图。你是在使用一个听者还是类似的东西？
