三大框架 SSM 搭建基础项目 Maven

本文转载自：https://www.cnblogs.com/leechenxiang/p/5328962.html 

很多新手在搭建ssm框架时可能会有一些不明白，今天在网上看到一篇写得比较详细的文章介绍搭建这三大框架的，于是就转载一下，方便更多人查看，仅供交流学习之用。看一下整合后的工程目录（单工程，多工程以后会采用maven）

5个package分别对应 action, entity, mapper（也就是DAO，采用动态代理）, service, service 实现类

resources 下 相关资源文件：

db.properties: 数据库连接参数

log4j.properties： 日志

applicationContext-dao.xml： spring 和 mybatis 整合的一些配置（sqlSessionFactory，mapper 配置）
applicationContext-service.xml： 业务
applicationContext.xml： spring 核心配置文件（配置一些公用的内容，比如数据源，事务）
springmvc.xml： springmvc 全局配置文件

SqlMapConfig.xml： mybatis 全局配置文件

 

webapp结构简单就不多说了

下面先贴出maven的pom内容：
