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;

import java.util.List;
import java.util.Map;

import com.hanqi.entity.Student;

public interface StudentDAO {
	
	//获取数据列表
	List<Student> find(int page , int rows,String sort,Map<String,String> where);
//获取数据条数
	int getTotal(Map<String,String> where);
	
	void insert(Student stu);//添加
	void update(Student stu);//修改
	void delete(String sno);//删除
}
