我跟着一些Spring MVC的教程和我的web.xml看起来是这样的:在根上下文和servlet上下文中加载应用程序上下文有什么好处吗?

我的问题是,什么是装载的servlet-context.xml中的根上下文和servlet上下文两个好处?我是一个春季框架新手,我不太了解春季框架。
为了更好地理解在根和应用方面的区别就在这里看我的答复在http://stackoverflow.com/questions/19619539/understanding-contexts-in-spring-mvc/19621534# 19621534 – Shailendra
另外,[this](http://stackoverflow.com/questions/11708967/what-is-the-difference-between-applicationcontext-and-webapplicationcontext-in-s)。除了模块分离以外,没有任何实际的好处。 –
