這是一個spring mybatis springMVC 的整合 裏面包括日誌，druid，的配置。可以說是一個現成的模板，直接復制下來就能用。

首先是web.xml

web.xml 中包括

• Spring beans 配置文件所在目錄
• utf-8編碼過濾器
• spring的監聽器
• springmvc的配置
• druid的配置
• 默認的首頁index

這裏說一下，springmvc沒有指定springmvc的配置文件的位置，因為springmvc默認是去web-info文件夾下找spring-servlet.xml的配置文件的。需要註意一下。這裏配置druid是因為我們要利用durid來監測我們訪問的url，

durid是一個非常出色數據庫連接池。非常的強大，他自帶的有監控界面，需要配置一下。
