The priority property is only used during preloading. By default, preloading is turned off so setting this property would do nothing. Preloading eagerly loads all deep links after the application boots instead of on demand as needed. To enable preloading, set preloadModules in the main application module config to true

在3.10的版本有懒加载，并未看到有预加载的功能，比较重要的页面只能使用正常加载的方式。
