基于xml配置实现事务管理

1.在spring配置文件中进行配置

①配置事务管理器

②配置通知

③配置切入点和切面

    <context:component-scan base-package="spring"></context:component-scan>
    <!--引入外部属性文件-->
    <context:property-placeholder location="classpath:/jdbc.properties"/>

    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" >
        <property name="driverClassName" value="${jdbc.driverClassName}"></property>
        <property name="url" value="${jdbc.url}"></property>
        <property name="username" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>

    <!--创建jdbcTemplate对象-->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <!--注入dataSource属性-->
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!--1.创建事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!--2.配置通知-->
    <tx:advice id="txadvice">
        <!--配置事务参数-->
        <tx:attributes>
            <!--指定哪种规则的方法上面添加事务-->
            <tx:method name="transfer" propagation="REQUIRED"/>
            <!--<tx:method name="trans*"/> 方法名以trans开头方法都会加上事务操作-->
        </tx:attributes>
    </tx:advice>

    <!--3.配置切入点和切面-->
    <aop:config>
        <!--配置切入点-->
        <aop:pointcut id="pt" expression="execution(* spring.service.AccountService.*(..))"/>
        <!--配置切面-->
        <aop:advisor advice-ref="txadvice" pointcut-ref="pt"></aop:advisor>
    </aop:config>
</beans>

 

测试代码

@Test
    public void test4(){
        ApplicationContext context = new ClassPathXmlApplicationContext("transation-config.xml");
        AccountService accountService = context.getBean("accountService", AccountService.class);
        accountService.transfer();
    }
