1.Spring与Hibernate整合
需要配置的就是hibernate和bean.xml
1)关键点:sessionFactory创建交给SpringIOC;session的事务处理交给Spring的事务处理
2)jar包:
连接池/数据库驱动包
Hibernate相关jar
Spring 核心包(5个)
Spring aop 包(4个)
spring-orm-3.2.5.RELEASE.jar【spring对hibernate的支持】
spring-tx-3.2.5.RELEASE.jar【事务相关】
3)整合步骤:A:创建sessionFactory 的bean节点;B:对逻辑层的业务方法添加事务
A:sessionFactory整合在Spring bean中的三种方式:
1.全部hibernate.cfg.xml引入bean.xml中
2.部分引入:dataSource连接池写在Spring中
3.全部在bean.xml中写
B:对逻辑层添加事务用aop事务方式
4)例子:
