SSM重新开发计科院新闻网站

1.什么是SSM

SSM就是Spring+SpringMVC+MyBatis框架的整合。

1.1 Spring

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。

1.2 SpringMVC

Spring MVC属于SpringFrameWork的后续产品，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，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，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。

这次我分了2个配置文件，分别是spring-mybatis.xml，包含spring和mybatis的配置文件，还有个是spring-mvc的配置文件，此外有2个资源文件：jdbc.propertis和log4j.properties。完整目录结构如下：

使用框架的版本：

Spring 4.0.2 RELEASE

Spring MVC 4.0.2 RELEASE

MyBatis 3.2.6

2.效果图
