Model is an abstraction. 模型是一种抽象。 You could use Spring with servlets, portlets or other frontend technologies and Model attributes will always be available in your respective views. 您可以将Spring与servlet，portlet或其他前端技术一起使用，并且Model属性将始终在您各自的视图中可用。
HttpServletRequest on the other hand is an object specific for Servlets. 另一方面，HttpServletRequest是特定于Servlet的对象。 Spring will also make request attributes available in your views, so from a user perspective there is not much difference. Spring还将使请求属性在您的视图中可用，因此从用户角度看并没有太大区别。
Another aspect is that models are more lightweight and more convenient to work with. 另一方面是模型更轻巧，使用起来更方便。
