SSM -1

使用SSM（Spring、SpringMVC和Mybatis）已经有三个多月了，项目在技术上已经没有什么难点了，基于现有的技术就可以实现想要的功能，当然肯定有很多可以改进的地方。之前没有记录SSM整合的过程，这次刚刚好基于自己的一个小项目重新搭建了一次，而且比项目搭建的要更好一些。以前解决问题的过程和方法并没有及时记录，以后在自己的小项目中遇到我再整理分享一下。这次，先说说三大框架整合过程。个人认为使用框架并不是很难，关键要理解其思想，这对于我们提高编程水平很有帮助。不过，如果用都不会，谈思想就变成纸上谈兵了！！！先技术，再思想。实践出真知。（可通过图片水印查看博客地址）

1、基本概念

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。

2、开发环境搭建

如果需要，参看之前的博文：http://blog.csdn.net/zhshulin/article/details/30779873

3、Maven Web项目创建

如果需要，参看之前的博文：http://blog.csdn.net/zhshulin/article/details/37921705

4、SSM整合    

        下面主要介绍三大框架的整合，至于环境的搭建以及项目的创建，参看上面的博文。这次整合我分了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：

使用框架都是较新的版本：

       Spring 4.0.2 RELEASE

       Spring MVC 4.0.2 RELEASE

       MyBatis 3.2.6

4.1、Maven引入需要的JAR包

 为了方便后面说的时候不需要引入JAR包，我这里直接给出所有需要的JAR包，这都是基本的JAR包，每个包的是干什么的都有注释，就不再多说了。
