java - 本机库 D:\jdk 1.8.0 181\jre1.8.0_181\bin\glass.dll 已在另一个类加载器中加载

Question

我的问题是当我将 Powermock 与 ApplicationTest 或 GuiTest 一起使用时。我给 Native Library D:\jdk 1.8.0 181\jre1.8.0_181\bin\glass.dll 已经加载到另一个类加载器中。所以我必须在不使用 ApplicationTest 或 GuiTest 的情况下展示舞台。或者有没有解决方案。我尝试https://maven.apache.org/surefire/maven-surefire-plugin/examples/class-loading.html解决方案，但它没有解决我的问题。我无法运行我的单元测试。

public class AlertMessagesTest extends TestFXGuiBase{
    @Test
    public void setMessage() throws Exception {
        Platform.runLater(() -> AlertMessages.setMessage(AlertMessages.AlertMessagesType.NAME, ""));
        functions.sleep(1000);
        functions.clickOn("Ok");
    }} 

public class AreaController extends SystemAdministrationManagement {  

static {
    System.loadLibrary ("glass.dll");
}

public void loadAreaManagement() throws Exception {
    super.addSearchIconToTextField(filterText);

    setVersion();

    data = FXCollections.observableArrayList();
    filteredData = new FilteredList(getData(), p -> true);

    addAreaNadModeListToTableView();
}
}

@RunWith(PowerMockRunner.class)
@PrepareForTest({Database.class, AlertManager.class, AreaController.class})
@SuppressStaticInitializationFor("gov.sysadmin.areaManagement.AreaController")
public class AreaControllerTest extends TestFXGuiBase {

    FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/fxml/areaManagement/area.fxml"));

    @Test
    public void showAreaNadModeListTestFunction() throws Exception{
        TrainLine trainLine = new TrainLine();
        trainLine.setId(1);
        trainLine.setName("Name");
        trainLine.setExp("Explanation");

        Area firstArea = new Area();
        firstArea.setId(1);
        firstArea.setShortname("BSM");
        firstArea.setLongname("BSM");
        firstArea.setTrainline(1);
        firstArea.setOrderno((byte) 1);
        firstArea.setAddressxml(null);
        firstArea.setAreaxml(null);
        firstArea.setExplanation("BSM");
        firstArea.setTrainlineByTrainline(trainLine);
        firstArea.setIsautonad(false);

        DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
        Date secondAreaDayStartTime = dateFormat.parse("08:00:00");
        Date secondAreaNightStartTime = dateFormat.parse("21:00:00");

        Area secondArea = new Area();
        secondArea.setId(2);
        secondArea.setShortname("BND");
        secondArea.setLongname("BND");
        secondArea.setTrainline(1);
        secondArea.setOrderno((byte) 2);
        secondArea.setAddressxml(null);
        secondArea.setAreaxml(null);
        secondArea.setExplanation("");
        secondArea.setTrainlineByTrainline(trainLine);
        secondArea.setDaystart(new Time(secondAreaDayStartTime.getTime()));
        secondArea.setDaystart(new Time(secondAreaNightStartTime.getTime()));
        secondArea.setIsautonad(true);

        List<Area> areaList = new ArrayList<Area>();
        areaList.add(firstArea);
        areaList.add(secondArea);

        PowerMock.suppressConstructor(Database.class);
        PowerMock.mockStatic(Database.class);
        Database mockDatabase = EasyMock.createMock(Database.class);
        EasyMock.expect(Database.getInstance()).andReturn(mockDatabase).anyTimes();
        EasyMock.expect(mockDatabase.getAllArea()).andReturn(areaList);
        EasyMock.expectLastCall().times(1);
        PowerMock.replay(Database.class);
        PowerMock.replay(mockDatabase);

        AreaController areaNadModeListController = fxmlLoader.getController();
        AreaController spy = Mockito.spy(areaNadModeListController);
        Mockito.doNothing().when(spy).setVersion();
        spy.loadAreaManagement();

        EasyMock.verify(mockDatabase);
    }
