java - Spring 事务管理 : Cannot resolve reference to bean 'transactionManager'

Question

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中实例化 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");
    }
}

错误信息是:

错误消息的第一行说:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'txAdvice': Cannot resolve reference to bean 'transactionManager' while setting bean property 'transactionManager'; 

这似乎表明未设置 transactionManager。但我确实在我的 beans.xml 文件中设置了该设置。

我试了很多次都搞不明白。是什么导致了这个问题？

Answer 1

java.lang.ClassNotFoundException: org.aspectj.weaver.tools.PointcutDesignatorHandler

意味着你需要依赖

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.7.4</version>
</dependency>
