springmvc + shiro 配置（一、结构及配置文件）

springmvc + shiro 配置

最近自己做的项目框架升级之后，一直没有时间来整理一个完整的配置笔记，大都是一些小问题，这两天项目得空，刚好整理一下，顺便也修正一下配置文件中的冗余配置和不规范。

整个框架涉及的部分分为以下几个部分：

SpringMVC配置

SpringMVC+Hibernate配置

SpringMVC+Ibatis配置

*SpringMVC+Shiro配置

为什么配置了两个持久层

SpringMVC的优缺点在此处就不再阐述，而持久层配置了两个的原因在于两者的优势和不足可以相互弥补。
**如此搭配也是初次尝试，在性能等方面的考虑和框架的冗余上必定考虑不足，如有明知的同学，请留言指出，万分感谢。**
在简单的增删改查上面，Hibernate做持久层无疑有着优势，利用IDE的功能可以快速的导出Entity和hbm.xml文件，而对这些简单的增删改查，hibernate所提供的find,save,update等方法，是十分便利的。然而，当处理复杂的表关系的时候，Hibernate的应用明显就要复杂很多，对于基础开发人员来说，具备足够的sql编写能力，但对于Hibernate的多表联查等复杂操作，及获取返回对象等就显得力有不逮，当团队里面需要快速开发的时候，就需要简化这些学习和摸索的时间，故用Ibatis来弥补这一缺点。
Ibatis在此场景里面最大的优势就是sql语句了，所有的操作都可以通过编写SQL语句来实现，这正好弥补Hibernate的不足。废话不多说，直接上代码。

spring的版本用的4.0+的，之前有文章记录
