spring的事务管理--idea实现

1.基于xml的实现

    1.1先建立一个表account

    

     1.2建立类 ，这个关于数据库的操做，前面的博客已经配置好了； 

public class OrderDao {
    public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
        this.jdbcTemplate = jdbcTemplate;
    }

    private JdbcTemplate jdbcTemplate;
    public void lessmoney(){
        String sql="update account set salary=salary-? where username=?";
        jdbcTemplate.update(sql,1000,"zhangsan");
    }
    public void moremoney(){
        String sql="update account set salary=salary+? where username=?";
        jdbcTemplate.update(sql,1000,"lisi");
    }

}

public class OrderService {
    public void setOrderDao(OrderDao orderDao) {
        this.orderDao = orderDao;
    }

    private OrderDao orderDao;
    public void accountchange(){
        orderDao.lessmoney();
        //制造个异常，事务不能进行，进行回滚
        int i=100/0;
        orderDao.moremoney();
    }
}

        1.3xml配置

<!--用xml的方式配置c3p0 链接数据-->
<bean id="datasource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <!--配置属性-->
    <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
    <property name="jdbcUrl" value="jdbc:mysql:///mysql"></property>
    <property name="user" value="root"></property>
    <property name="password" value="raoxiaobo123"></property>
</bean>

<!--事务管理 1.配置事务管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="datasource"></property>
</bean>
<!--2.配置事务加强-->
<tx:advice id="tx-advice" transaction-manager="transactionManager">
        <tx:attributes>
            <!--要加强的方法，account*为开头account的方法-->
            <tx:method name="account*"/>
        </tx:attributes>
</tx:advice>
<!--3.配置切面-->
<aop:config>
    <aop:pointcut id="pointcut1" expression="execution(* com.xiaobo.transaction.OrderService.*())"></aop:pointcut>
    <aop:advisor advice-ref="tx-advice" pointcut-ref="pointcut1"></aop:advisor>
</aop:config>
<bean id="orderService" class="com.xiaobo.transaction.OrderService">
    <property name="orderDao" ref="orderDao"></property>
</bean>
<bean id="orderDao" class="com.xiaobo.transaction.OrderDao">
    <property name="jdbcTemplate" ref="jdbcTemplate"></property>
</bean>
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="datasource"></property>
</bean>

         1.3xml测试

public class testDemo {
    @Test
    public void testTransaction(){
        ApplicationContext context=new ClassPathXmlApplicationContext("bean5.xml");
        OrderService orderService= (OrderService) context.getBean("orderService");
        orderService.accountchange();
    }
}

            1.4结果:报除数不能为0的错误，表中的数据未变化

2基于注解的方式

<!--用xml的方式配置c3p0 链接数据-->
 <bean id="datasource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
     <!--配置属性-->
     <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
     <property name="jdbcUrl" value="jdbc:mysql:///mysql"></property>
     <property name="user" value="root"></property>
     <property name="password" value="raoxiaobo123"></property>
 </bean>

 <!--事务管理 1.配置事务管理器-->
 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
     <property name="dataSource" ref="datasource"></property>
 </bean>
<!--2.开启事务注解-->
 <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
 <bean id="orderService" class="com.xiaobo.transaction.OrderService">
     <property name="orderDao" ref="orderDao"></property>
 </bean>
 <bean id="orderDao" class="com.xiaobo.transaction.OrderDao">
     <property name="jdbcTemplate" ref="jdbcTemplate"></property>
 </bean>
 <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
     <property name="dataSource" ref="datasource"></property>
 </bean>

         2.1对类进行注解

//第三步开启注解
@Transactional
public class OrderService {
    public void setOrderDao(OrderDao orderDao) {
        this.orderDao = orderDao;
    }

    private OrderDao orderDao;
    public void accountchange(){
        orderDao.lessmoney();
        //制造个异常，事务不能进行，进行回滚
        int i=100/0;
        orderDao.moremoney();
    }
}
