Question

我正在尝试为Hibernate设置Spring事务管理，但是，我遇到了以下问题......

java.lang.IllegalArgumentException: Cannot convert value of type [ac.nz.unitec.service.impl.UserServiceImpl] to required type [org.springframework.aop.Pointcut] for property 'pointcut': no matching editors or conversion strategy found

以下是更多细节和Spring配置

有一个名为UserService的接口，UserServiceImpl实现了该接口。

Spring配置：

<bean id="txManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<aop:config>
    <aop:pointcut id="userService"
        expression="execution(public * ac.nz.unitec.service.UserService.*(..))" />
    <aop:advisor advice-ref="txAdvice" pointcut-ref="userService" />
</aop:config>
             <!--I also tried the following one but didn't work out either-->
<aop:config>
    <aop:pointcut id="userService"
        expression="execution(public * ac.nz.unitec.service.impl.UserServiceImpl.*(..))" />
    <aop:advisor advice-ref="txAdvice" pointcut-ref="userService" />
</aop:config>

<tx:advice id="txAdvice" transaction-manager="txManager">
    <tx:attributes>
        <tx:method name="exist" />
        <tx:method name="add" />
    </tx:attributes>
</tx:advice>

<!--Not sure whether the following piece matters as it has duplicate name with the one in aop config-->

<bean name="userService" class="ac.nz.unitec.service.impl.UserServiceImpl">
    <property name="userDao" ref="userDao"/>
</bean>

更新了Spring Configuration xml：

非常感谢任何建议，谢谢你们提前

Answer 1

在旧的配置文件中，在aop：config中，aop：pointcut id是userService。但是，有一个bean，其名称也是userService。我将aop：pointcut id更改为userServiceOperation并修复了问题

无法将类型的值转换为所需类型[org.springframework.aop.Pointcut]
