1、SSM概述
SSM框架，即Spring + Spring MVC + MyBatis的缩写
1.Spring简介
Spring是一个开源框架，Spring是于2003年兴起的一个轻量级的Java开发框架，由Rod Johnson在其著作Expert One-On-One J2EE Development and Design中阐述的部分理念和原型衍生而来。它是为了解决企业应用开发的复杂性而创建的。Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。然而，Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。 简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。
2.Spring MVC简介
Spring MVC属于Spring Framework的后续产品，已经融合在Spring Web Flow里面，它原生支持的Spring特性，让开发变得非常简单规范。Spring MVC 分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。
3.MyBatis简介
MyBatis本是apache的一个开源项目iBatis, 2010年这个项目由apache software foundation 迁移到了google code，并且改名为MyBatis 。MyBatis是一个基于Java的持久层框架。iBATIS提供的持久层框架包括SQL Maps和Data Access Objects（DAO）MyBatis消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis使用简单的XML或注解用于配置和原始映射，将接口和Java的POJOs（Plain Old Java Objects，普通的 Java对象）映射成数据库中的记录。可以这么理解，MyBatis是一个用来帮你管理数据增删改查的框架。
