Question

我一直在经历这个奇怪的问题。我正在创建一个具有登录屏幕的JavaFX应用程序。

问题是每当我输入用户名和密码后按Enter键，我会遇到以下致命错误。如果我使用“登录”按钮，它可以正常工作。

以下是用于检测ENTER键的用户名字段和密码字段的动作侦听器：

fieldUsername.setOnKeyPressed((KeyEvent event) -> {
    if (event.getCode() == KeyCode.ENTER) {
        KeyEvent.fireEvent(buttonLogin, new MouseEvent(MouseEvent.MOUSE_CLICKED, 0, 0, 0, 0, MouseButton.PRIMARY, 1, true, true, true, true, true, true, true, true, true, true, null));
    }
});

fieldPassword.setOnKeyPressed((KeyEvent event) -> {
    if (event.getCode() == KeyCode.ENTER) {
        KeyEvent.fireEvent(buttonLogin, new MouseEvent(MouseEvent.MOUSE_CLICKED, 0, 0, 0, 0, MouseButton.PRIMARY, 1, true, true, true, true, true, true, true, true, true, true, null));
    }
});

每当我按下ENTER键时，我都会触发登录按钮。

以下是buttonLogin的动作监听器：

buttonLogin.setOnMouseClicked((MouseEvent event) -> {
    CheckLoginAndPin c1 = new CheckLoginAndPin();
    if (!fieldUsername.getText().isEmpty() && !fieldPassword.getText().isEmpty()) {
        if (c1.checkUsername(fieldUsername.getText())) {
            if (c1.login(fieldUsername.getText(), fieldPassword.getText())) {
                ArrayList<String> arrayListGetUserDetails = c1.getPriviledge(fieldUsername.getText());
                stageLogin.close();
                MainFrame mainFrame = new MainFrame(arrayListGetUserDetails.get(0), arrayListGetUserDetails.get(1), arrayListGetUserDetails.get(2), fieldUsername.getText());
            } else {
                PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "Password incorrect", fieldPassword, 100, 60);
            }
        } else {
            PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "User name incorrect", fieldUsername, 100, 60);
        }
    } else {
        if (fieldUsername.getText().isEmpty() && !fieldPassword.getText().isEmpty()) {
            PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "User name can not be empty", fieldUsername, 100, 60);
        } else if (fieldPassword.getText().isEmpty() && !fieldUsername.getText().isEmpty()) {
            PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "Password can not be empty", fieldPassword, 100, 60);
        } else if (fieldUsername.getText().isEmpty() && fieldPassword.getText().isEmpty()) {
            PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "User name & password can not be empty", fieldUsername, 100, 60);
        }
    }
});
