SSM框架及项目搭建总结
1、Mybatis
2、Spring
- Rod Jahnson,Spring Framework创始人,著名作者,悉尼大学的博士,专业是音乐学。
- spring理念:使现有的技术更加容易使用,本身是一个大杂烩,整合了现有的技术框架!
- 一个轻量级的,开源的,免费的框架(容器)。
- 支持事务的处理,对框架整合的支持!
- ***总结一句话:Spring就是一个轻量级的控制反转(IOC)和面向切面编程(AOP)的框架!
- 详情见:https://www.cnblogs.com/mc-blog/p/15139093.html
3、SpringMVC
- MVC是模型(Model)、视图(View)、控制器(Controller)的简写,是一种软件设计规范。
- 是将业务逻辑、数据、显示分离的方法来组织代码。
- MVC主要作用是降低了视图与业务逻辑间的双向偶合。
- MVC不是一种设计模式,MVC是一种架构模式。当然不同的MVC存在差异。
- Spring MVC是Spring Framework的一部分,是基于Java实现MVC的轻量级Web框架。
