Struts2+Hibernate+Spring整合-优快云博客

本文链接：https://blog.youkuaiyun.com/tianjunwenhappy/article/details/60473611

本文介绍了一个使用Spring、Struts2和Hibernate（SSH）框架搭建的商品添加系统。该系统包括了从配置文件设置到各层具体实现的完整过程，适合初学者学习。

最近做了一个小小的整合项目，下面和大家分享一下原工程。

这是一个简单的商品添加系统。非常的简单，比较适合想我一样刚刚接触SSH框架的朋友看看。

一、导入Spring、Struts2、Hibernate需要的包和mysql，c3p0需要的jar包；

链接：http://pan.baidu.com/s/1dF67r3N 密码：x2xy

二、引入Struts.xml，log4j.properties，applicatioContext.xml，文件

三、配置web.xml文件：

1.配置需要的监听器和过滤器；

四、配置applicationContext.xml文件：

1.配置外部数据库连接文件（jdbc.properties）;

2.在ApplicationContext.xml中引入jdbc.properties文件；

3.配置连接池信息；

4.配置Hibernate相关属性:

1）注入连接池；

2）配置相关属性（数据库方言，显示sql语句，格式化输出sql语句，创建数据库的方式）；

3）载入映射文件；

五、配置Action类

六、配置业务层的类（service)

七、配置DAO的类

八、配置事务管理器并开启事务

以下是对应配置文件：

ApplicationContext.xml代码：
