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
