1.什么是SSM
SSM就是Spring&＃43;SpringMVC&＃43;MyBatis框架的整合。
1.1 Spring
Spring是一个开源框架&＃xff0c;Spring是于2003 年兴起的一个轻量级的Java 开发框架&＃xff0c;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&＃xff0c;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&＃xff0c;任何Java应用都可以从Spring中受益。 简单来说&＃xff0c;Spring是一个轻量级的控制反转&＃xff08;IoC&＃xff09;和面向切面&＃xff08;AOP&＃xff09;的容器框架。
1.2 SpringMVC
Spring MVC属于SpringFrameWork的后续产品&＃xff0c;已经融合在Spring Web Flow里面。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&＃xff0c;这种分离让它们更容易进行定制。
1.3 MyBatis
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&＃xff0c;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&＃xff08;DAO&＃xff09;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&＃xff0c;将接口和 Java 的POJOs&＃xff08;Plain Old Java Objects&＃xff0c;普通的 Java对象&＃xff09;映射成数据库中的记录。
这次我分了2个配置文件&＃xff0c;分别是spring-mybatis.xml&＃xff0c;包含spring和mybatis的配置文件&＃xff0c;还有个是spring-mvc的配置文件&＃xff0c;此外有2个资源文件&＃xff1a;jdbc.propertis和log4j.properties。完整目录结构如下&＃xff1a;
使用框架的版本&＃xff1a;
Spring 4.0.2 RELEASE
Spring MVC 4.0.2 RELEASE
MyBatis 3.2.6
