Отображает related problem при подставлении переменной вместо стрингового значения в аннотации Appium @AndroidFindBy ( переменная)

Изучаю Аппиум. Столкнулся с такой проблемой: в IDEA отобажает Related problem над переменной, которую я использую для сохранения части ID. Дело в том, что первая часть ID элемента состоит из appPackagе, а вторая -это id элемента на экране аппиум. Мне нужно, чтоб первая часть была изменяемая. Я ее поместил в String переменную. И во всех классах моей программы это работате, кроме одного.

 public class BaseSetup < //обьявление переменных private DesiredCapabilities cb =new DesiredCapabilities(); private static AndroidDriver ad =null; private String port = "4723"; private String server = "127.0.0.1"; **//тут я объявляю эту переменную, которая имеет значение для appPackage** protected String myapp = "com.covantex.mediker"; @BeforeClass //публичный класс для вызова приватного класса public void setUp() throws MalformedURLException < initDriver(); >/* метод который будет возвращать драйвер для передачи его следующим страницам при переходе на другие активити а так же получения драйвера в пределах текущего активити */ public AndroidDriver getDriver() < return ad; >//приватный класс с данными для запуска сессии private void initDriver() throws MalformedURLException < //создание экземпляра класа для передачи парамеров запуска приложения на устройстве DesiredCapabilities ds =new DesiredCapabilities(); ds.setCapability(MobileCapabilityType.DEVICE_NAME,"374c3291"); ds.setCapability("platformName", "Android"); ds.setCapability( "appPackage", myapp); ds.setCapability( "appActivity", "com.meetMyDoc.ui.activity.LoginActivity"); ds.setCapability("noReset",true ); String url = "http://"+server+":"+port+"/wd/hub"; //инициализация андроид райвера + ексепшин для отлова ошибок try< System.out.println("Драйвер проинициализирован с такими данными: " + url); ad = new AndroidDriver(new URL(url), ds); >catch (NullPointerException|MalformedURLException ex) < throw new RuntimeException("Андроид драйвер не может быть проинициализирован :("); >System.out.println("Не инициализирован: " +ad); > > 

// наследование от BaseSetup public class Driver extends BaseSetup < protected AndroidDriver ad; //это конструктор, где происходит инициализация драйвера родителя protected Driver()< this.ad = super.getDriver(); >> 

От драйвера наследуется MainPage, в котором я тоже использую переменную myapp как части id для нахождения элемента на экране.

public class MainPage extends Driver < public void clickBtn() throws InterruptedException < Thread.sleep(3000); MobileElement el3 = (MobileElement) ad.findElementById(myapp + ":id/btnLogin"); el3.click(); >public void sendCredentials() throws InterruptedException < Thread.sleep(2500); //тут работает MobileElement el1 = (MobileElement) ad.findElementById( myapp + ":id/etUserName"); el1.sendKeys("admin"); // и тут работает MobileElement el2 = (MobileElement) ad.findElementById( myapp + ":id/etPassword"); el2.sendKeys("admin"); >

Дальше я использую класс ScreenFormPF. Именно в нем я пытаюсь использовать myapp переменную. Именно в аннотации. И тут эта переменная подчеркивается красным. И пишет Related problem.

 public class ScreenFormPF extends MainPage < public ScreenFormPF( )< PageFactory.initElements(new AppiumFieldDecorator(ad), this); >// тут уже не работает и подчеркивает красным @AndroidFindBy(id = "com.covantex.mediker:id/etUserName") private AndroidElement login; // тут тоже не работает @AndroidFindBy(id = "com.covantex.mediker:id/etPassword") private AndroidElement password; >

ServletOutputStream: ServletResponse.getOutputStream() returns a ServletOutputStream suitable for writing binary data in the response. The servlet container does not encode the binary data, it sends the raw data as it is.

PrintWriter: ServletResponse.getWriter() returns PrintWriter object which sends character text to the client. The PrintWriter uses the character encoding returned by getCharacterEncoding(). If the response’s character encoding has not been specified then it does default character encoding.

queryForObject is not recorded when there is no record, and this exception will not throw this exception for the type of Query () LIST. The solution is to capture this exception and then return NULL in catch. The modification code is as follows:

 @Override public User findByUsername(String username) < User user=null; try< // 1. Define SQL String sql="select * from tab_user where username= ?"; // 2. Execute SQL user= template.queryForObject(sql, new BeanPropertyRowMapper(User.class), username); >catch (Exception e) < return null; >>

Default is false true This configuration means that the placeholder in the specified properties file is filtered, the placeholder is the form of $ , and Maven will automatically read the configuration file, then resolve the placeholder, use the above POM file. Defined attributes replace ->
