如上是application-Context.xml配置文件。下面看一下web.xml

如下是springmvc-servlet.xml的配置文件。知道为啥叫spring-mvc的配置文件吗？是因为我在web.xml配置文件里面说明了，dispatch-servlet 的名称为springmvc的原因吗？？？？

一、spring 事务申明步骤
1.1 首先申明命名空间和schema
首先需要引入aop 以及tx 的申明和schema
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" //申明通知
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">//申明schema
1.2 申明组件扫描的包路径
<context:componet-scan base-package=""/>
因为我在springmvc-servlet.xml文件里面申明了扫描包路径，并且将applicationContext.xml引入。所以就不需要在applicationContext.xml申明了。
