web.xml中加载顺序是context-param -> listener -> filter -> servlet并不因在web.xml中配置顺序而改变
以自己的项目tdsTest为例
1. 首先读取web.xml中设置，根据<context-param> name为contextConfigLocation取相应的值，如
<param-value>classpath:application.xml</param-value>
2.获取application.xml相应的设置，像这个project,就有import一个spring-mybatis.xml设置，然后初始化数据库相关配置
3. spring-mybatis.xml配置了数据库连接，mybatis印射的相关信息，从哪个地方去找mapper及mapper.xml,事务日志管理等
4.然后init DispatcherServlet,这里配置spring-mvc.xml servlet相关信息，比如自动扫描Controller,ServiceImpl，静态资源等
