我这里将除pom、web之外的所有的配置文件均放在resources资源文件中。设置resources方法：在src/main/java文件夹下创建resources文件夹，右击文件夹，选择Build Path，选择use as Source Folder即可

项目中，我将applicationContext.xml、config.properties、logback.xml、springmvc.xml等项目支持配置文件放在config文件夹中；将与MyBatis相关的配置文件放在mybatisConfig文件夹中

我将界面WEB-INF/page/都放置在WEB-INF文件夹下，这样外部便无法直接访问jsp文件
