2、Spring开发的jar文件

1、所需要的jar文件

源码, jar文件：spring-framework-3.2.5.RELEASE

commons-logging-1.1.3.jar 日志

spring-beans-3.2.5.RELEASE.jar bean节点

spring-context-3.2.5.RELEASE.jar spring上下文节点

spring-core-3.2.5.RELEASE.jar spring核心功能

spring-expression-3.2.5.RELEASE.jar spring表达式相关表

spring-asm-3.2.0.M1.jar

以上是必须引入的5个jar文件，在项目中可以用户库管理！

2、核心配置文件: applicationContext.xml

Spring配置文件：applicationContext.xml / bean.xml

配置文件的很全的一个
