第一次做SSM框架项目 学习笔记
首先先介绍什么是SSM?
Spring+SpringMVC+Mybatis 就是SSM的简称
Spring
一，Spring是一个开源框架，它能降低开发企业应用程序的复杂性，降低了开发成本并整合了各种流行框架，它以IOC和AOP(面向切面编程)二种先进的技术基础完美的简化了企业级开发的复杂度。包含以下七个模块
1，Spring core 模块
2，Context模块
3，AOP模块
4，DAO模块
5，ORM映射模块
6,Web模块
7，MVC模块
二，SpringMVC是典型的MVC模式设计模式，围绕DispatcherServlet核心控制器展开，核心控制器就是截获请求，分发到相应的业务控制器，由业务控制器调用业务处理方法处理业务逻辑，返回一个模型和视图对象，核心控制器在根据此对象找到视图显示出结果。
三，mybatis是支持SQL查询，储存过程和高级映射的优秀持久层框架。。MyBatis 消除
了几乎所有的 JDBC 代码和参数的手工设置以及对结果集的检索。MyBatis 可以使用简单的
XML 或注解用于配置和原始映射，将接口和 Java 的 POJO（Plain Old Java Objects，普通的
Java 对象）映射成数据库中的记录
以上是对于整合框架的一个简单介绍概念性的东西大都是出自书本，下面将贴出我做的这个项目的具体配置文件，
