因为直接使用了SpringMVC,所以之前一直不明白xxx-servlet.xml和applicationContext.xml是如何区别的,其实如果直接使用SpringMVC是可以不添加applicationContext.xml文件的。
使用applicationContext.xml文件时是需要在web.xml中添加listener的:

org.springframework.web.context.ContextLoaderListener

Spring lets you define multiple contexts in a parent-child hierarchy.

The applicationContext.xml defines the beans for the "root webapp context", i.e. the context associated with the webapp.

The spring-servlet.xml (or whatever else you call it) defines the beans for one servlet's app context. There can be many of these in a webapp, one per Spring servlet (e.g. spring1-servlet.xml for servlet spring1, spring2-servlet.xml for servlet spring2).

Beans in spring-servlet.xml can reference beans in applicationContext.xml, but not vice versa.

All Spring MVC controllers must go in the spring-servlet.xml context.

In most simple cases, the applicationContext.xml context is unnecessary. It is generally used to contain beans that are shared between all servlets in a webapp. If you only have o

applicationContext.xml是文件,是Spring的配置文件
SpringMVC是web架构方式,包含了Spring
