我有以下bean配置XML文件（beans.xml）：
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="createWithContactInfo"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="createOperation"
expression="execution(* com.example.db.CustomerJDBCTemplate.createWithContactInfo(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="createOperation" />
</aop:config>
<!-- Initialization for data source -->
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/Customer" />
<property name="username" value="myusername"/>
<property name="password" value="12345"/>
<property name="initialSize" value="10"/>
</bean>
<!-- Definition for customerJDBCTemplate bean -->
<bean id="customerJDBCTemplate" class="com.example.db.CustomerJDBCTemplate">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
但是，当我执行以下测试以从应用程序上下文实例化bean时，它会在第一行抛出异常：
public class MyTest {
public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
CustomerJDBCTemplate dao = (CustomerJDBCTemplate) ctx.getBean("customerJDBCTemplate");
Date dob = new Date(90, 9, 10);
dao.createWithContactInfo("m9086", "Sam", dob, "David", "123456", "a123@example.com");
}
}
错误消息是：

错误消息的第一行显示：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'txAdvice': Cannot resolve reference to bean 'transactionManager' while setting bean property 'transactionManager';
似乎表明transactionManager未设置。但我确实在beans.xml文件中设置了该设置。
我多次尝试过，但无法理解。是什么导致了这个问题？
答案 0 :(得分：6)
