如何配置 Spring 以使用 TransactionManager

Question

我正在尝试了解如何使用 Spring DataSourceTransactionManager。

我正在尝试关注这个example。 但是，当我从 Eclipse 启动 Tomcat 时，我得到了这个错误：

这是DispatcherServlet.xml的相关代码

   <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">          
             <property name="dataSource" ref="dataSource"/>
         </bean>    

        <tx:advice id="txAdvice" transaction-manager="transactionManager">
            <tx:attributes>
                <tx:method name="create" />
            </tx:attributes>
        </tx:advice>

        <aop:config>
            <aop:pointcut id="userDaoTxPointcut" expression="execution(* com.springgestioneerrori.DAO.UtenteDAO.salvaUtente(..))" />
            <aop:advisor advice-ref="txAdvice" pointcut-ref="userDaoTxPointcut" />
        </aop:config>   

salvaUtente() 是我将处理多个 inserts 的方法（现在仍然是 exmpty）。

您的类路径中缺少一个 jar：

<dependency>    
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>${aspectjweaver.version}</version>    
</dependency>
