SSH程序框架之Spring与HIbernate整合

spring整合hibernate 有两种方式 1、注解方式 2、xml方式实现

　　Spring整合Hibernate有什么好处？

　　1、由IOC容器来管理Hibernate的SessionFactory

　　2、让Hibernate使用上Spring的声明式事务

1.xml方式：

   大概架构：                                 

                                  

 

我们将会创建一个账户类，实现添加的功能 

首先先添加Spring 和 HIbernate的jar包节点：

 

 1  <dependencies>
 2         <dependency>
 3             <groupId>junit</groupId>
 4             <artifactId>junit</artifactId>

 6             <scope>test</scope>
 7         </dependency>

 9         <!--jta的jar包-->
10         <dependency>
11             <groupId>javax.transaction</groupId>

14         </dependency>
15 
16         <!--mysql数据库驱动-->

27         </dependency>
28 
29         <!--以上是HIbernate的jar包配置-->
30 
31         <!--下面是Spring相关的jar包配置-->
32         <!--c3p0-->
