 xml顶部需要加上：xmlns:tx=http://www.springframework.org/schema/tx

xsi:schemaLocation="http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd" 支持事务。

 jdbc.properties

#mysql configuration

jdbc.mysql.className = com.mysql.jdbc.Driver

jdbc.mysql.url = jdbc:mysql://localhost:3306/sms

jdbc.mysql.user = test

jdbc.mysql.password = test

jdbc.mysql.dialect = org.hibernate.dialect.MySQL5Dialect

 

支持jar包~!

cglib-nodep-2.1_3.jar

commons-dbcp.jar

commons-pool.jar

mysql-connector-java-3.1.11.jar 并启动mysql服务~!

Spring2.5注解事务说明~!

1. 如果事务管理器的id是transactionManger，这里可以不对transaction-manager进行配置，即<tx:annotation-driven />就可以了。
2. 这个配置是告诉spring在类（接口）层面或者方法层面上检查应用程序上下文中的所有标准了@Transactional的bean，spring将自动把事务通知的内容通知给它。
3. 这个通知的事务参数将由@Transactional注释的参数来定义
4. 如果注释的是接口，则该接口的所有实现类都将被事务化。
