启动Spring容器，在web.xml文件中配置Spring容器：
<!-- 启动Spring 容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<!-- 指定配置文件位置 -->
<param-value>classpath:spring-config.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>在spring-config.xml 开启自动包扫描，Spring不需要接管Controller

jdbc.url=jdbc:mysql://localhost:3306/mybatis配置事务管理器，让他控制住数据源里面的连接的关闭和提交
<!-- 配置事务控制 -->
<bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="comboPooledDataSource"/>
</bean>配置事务切面
<!-- 事务增强、事务属性、事务建议
- transaction-manager：指定事务管理器
-->
<tx:advice id="myTx" transaction-manager="dataSourceTransactionManager">
<!-- 配置事务属性 -->
<tx:attributes>
<!-- 任何方法发生异常就回滚

</filter-mapping>在springmvc-config.xml开启自动包扫描，需要禁用默认行为，因为默认行为是全包扫描，SpringMVC只需要接管Controller类

<!-- 接管被Controller接管的类 -->

</context:component-scan>
</beans>防止静态或动态资源失效。加上这两个配置
