Java7到Java8 - UI问题，Javafx应用程序中元素之间的间距。
这不是重复问题，因为我已经确定了默认皮肤。
当我使用Java7运行我的应用程序时，它显示正确的UI，具有适当的背景颜色。 但是当我使用Java8运行相同的应用程序时，它显示的UI与Java7的UI不同。 某些元素重叠，例如GridPane中的按钮，GridPane中的元素之间的某些间距减小，而背景颜色未正确设置。
目前，我在FXML文件中引用了CSS，但是在删除之后我进行了测试。仍存在问题。
请提供解决方案，以便我可以使用Java7和Java8为javafx应用程序提供相同的UI。
我尝试通过以下两种方式解决问题。
1.在控制器的舞台方法中使用System.setProperty（＆＃34; javafx.userAgentStylesheetUrl＆＃34;，＆＃34; CASPIAN＆＃34;）。
2.在命令行上使用-Djavafx.userAgentStylesheetUrl = caspian运行。
以下是样本

MainApp.java
public class MainApp extends Application {
@Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("/fxml/t1.fxml"));
Scene scene = new Scene(root);
scene.getStylesheets().add("/style/Style.css");
System.setProperty( "javafx.userAgentStylesheetUrl", "CASPIAN" );
stage.setTitle("JavaFX and Maven");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
我使用-Djavafx.userAgentStylesheetUrl = caspian参数运行应用程序
查看Java7中的这种XML差异＆amp; Java8如下面的链接图像所示
