用spring配置一个事务,配置出现问题了,求教

今天整合个ssm框架,在配置事务时出现这种错误:

配置文件内容如下:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xmlns:aop="http://www.springframework.org/schema/aop"

	xmlns:context="http://www.springframework.org/schema/context"

	xmlns:mvc="http://www.springframework.org/schema/mvc"

	xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring"

	xmlns:tx="http://www.springframework.org/schema/tx"

	xmlns:util="http://www.springframework.org/schema/util"

	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd

		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd

		http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.3.xsd">

	

	<!-- 配置事务管理器 -->

	<bean id="transactionManager" 

			class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

		<property name="dataSource" ref="dataSource" ></property>

	</bean>

	

	<tx:advice transaction-manager="transactionManager" >

		<tx:attributes>

			<tx:method name="delete" propagation="REQUIRED" />

			<tx:method name="insert" propagation="REQUIRED" />

			<tx:method name="update" propagation="REQUIRED" />

		</tx:attributes>

	</tx:advice>

	

	<aop:config>

		<aop:pointcut expression="execution(* com.ssm.service.Imp.*.*(..))" id="pointcut"/>

		<aop:advisor advice-ref="transactionManager" pointcut-ref="pointcut"/>

	</aop:config>

</beans>

另外我的数据源是配置在另一个dao文件的:

之前看视频,数据源是可以直接引用的,不知道是不是这里出问题
web.xml的配置如下:

<context-param>

	<param-name>contextConfigLocation</param-name>

	<param-value>

		/WEB-INF/classes/spring/applicationContext-*.xml

	</param-value>

  </context-param>

  <!-- 启动ioc容器的ServletContextListener -->

  <listener>

	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

所以想问一下，事务配置那部分为什么会这样报错，第一次遇见，萌新求教
