SSHE框架整合（增删改查）

1.前期准备：jar包（c3p0、jdbc ,各个框架）

web.xml文件：spring的   转码的，和Struts2的过滤器

　　Hibernate.cfg.xml的文件，并生成实体类的映射文件，

注意：现在用spring来生成映射文件。

spring的app.xml的配置，用的连接池来连接数据库

Hibernate的各种配置，sessionFactory声明当前session，通过sessionFactory.getCurrentSession()来获取，（DAO层）

声明事务

然后见如下图所示的各种包，在包中实现各接口以及实现类（impl）实现类中主要是个方法（增删改查）

Struts2的配置，主要是Action的方法的配置，(增删改查的action)

注意：name是页面发送的get或post请求的URL地址，class是spring中对应的id， method是Action类中的方法名

 

DAO层接口

package com.hanqi.dao;
