<!-- class="org.springframework.jdbc.datasource.DriverManagerDataSource" -->

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">

<bean id="LoginAction" class="com.zyoung.actions.Login">   
    <property name="userService" ref="userService"></property>   
</bean> 

 <!-- bean中的class为实现接口的类；property的name为类中引用的属性名称；ref为spring注册的名称，如上面的client--> 
<bean id="userDao"  
    class="com.zyoung.dao.impl.UserDao">   
    <property name="client" ref="sqlMapClientTemplate" />
</bean>

<bean id="userService"  class="com.zyoung.service.impl.UserService">

<tx:advice id="txadvice" transaction-manager="Manager">

</aop:config>

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

[color=red]<!-- Introducation实验-->
<bean id="Iother" class="introduction.OtherImpl"/>

<bean id="advisorss" class="org.springframework.aop.support.DefaultIntroductionAdvisor">
    <constructor-arg index="0">
        <ref bean="Iother"/>
    </constructor-arg>
    <constructor-arg index="1">
        <value>introduction.IOther</value>
    </constructor-arg>
</bean>

<bean id="poxyOther" class="org.springframework.aop.framework.ProxyFactoryBean">

        <list>
            <value>advisorss</value>
        </list>
    </property>
</bean>[/color]  

错误：
org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'dataSource': Bean with name 'dataSource' has been injected into other beans [sqlMapClient, Manager] in its raw version as part of a circular reference, but has eventually been wrapped (for example as part of auto-proxy creation). This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesOfType' with the 'allowEagerInit' flag turned off, for example.
.....
我没加入
<!-- Introducation实验--> 以下配置时没报错，找了半天不知道哪循环依赖了，本人刚刚学spring 忘各位大侠详细解答，谢谢了

Answer 1

aop:aspectj-autoproxy/ 这里已经自动代理了所有bean

你用这个


com.zyoung.service.IUserService






advisorss

又再一次搞了一层代理bean
