这是一个spring mybatis springMVC 的整合 里面包括日志，druid，的配置。可以说是一个现成的模板，直接复制下来就能用。
首先是web.xml
web.xml 中包括
- Spring beans 配置文件所在目录
- utf-8编码过滤器
- spring的监听器
- springmvc的配置
- druid的配置
- 默认的首页index
这里说一下，springmvc没有指定springmvc的配置文件的位置，因为springmvc默认是去web-info文件夹下找spring-servlet.xml的配置文件的。需要注意一下。这里配置druid是因为我们要利用durid来监测我们访问的url，
durid是一个非常出色数据库连接池。非常的强大，他自带的有监控界面，需要配置一下。
