- 首先看一下web.xml,通过查看log4j的日志可以发现在服务器启动时applicationContext.xml是先于spring3-servlet.xml加载,因此applicationContext.xml中已经注册到beanfactory的bean在spring3-servlet.xml也是可以使用的,比如在applicationContext.xml中通过context:component-scan扫描了service和dao包,而在spring3-servlet.xml只扫描了web包,但web包中的Controller依然被注入了Service。
- web.xml各个标签的加载顺序:context-param -> listener -> filter -> servlet
