很多东西与上边的相同,这儿只简介;
导包。。。
数据库中建立三个表。。。
建立存放连接数据库的file文件:jdbc.properties;
-----------------------------------------------------------------
com.atguigu.spring.tx.xml包下建立,
接口:BookShopDao
类:BookShopDaoImpl 继承于接口,BookShopDao
异常处理类:BookStockException
测试类:JUnitTest
-----------------------------------------------------------------
com.atguigu.spring.tx.xml.service包下建立:在配置事物切点的时候便于识别<aop:pointcut expression="execution(* com.atguigu.spring.tx.xml.service.*.*(..))" id="txPointCut"/>
接口:BookShopService
接口:Cashier
-------------------------------------------------------------------
com.atguigu.spring.tx.xml.service.impl包下建立:
类:BookShopServiceImpl,继承于接口 BookShopService
类:CashierImpl,继承于接口 Cashier
------------------------------------------------------------------
