Configuration problem: Cannot locate BeanDefinitionDecorator for element [config] 或 [advice]

我今天在网上学搭框架，我在spring.xml配置的时候，我不是直接复制的，我是手把手敲了一遍，当然会有小错误。我把这个错误也记录一下。

其实很简单，你仔细对比你自己亲手敲得和别人测试通过的。你会发现很多地方不是位置放错了，就是字符错了。

不说多了，标题的错误已经告诉我们答案了。我先把错误配置代码贴出来：

<bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
        这里的</bean>去哪里了？
    <aop:config>
        <aop:pointcut id="transactionPointcut"
            expression="execution(* com.zou.test.service..*Impl.*(..))" />
        <aop:advisor pointcut-ref="transactionPointcut"
            advice-ref="transactionAdvice" />
    </aop:config>
    
    <tx:advice id="transactionAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="append*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="modify*" propagation="REQUIRED" />
            <tx:method name="edit*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="remove*" propagation="REQUIRED" />
            <tx:method name="repair" propagation="REQUIRED" />
            <tx:method name="delAndRepair" propagation="REQUIRED" />


            <tx:method name="get*" propagation="SUPPORTS" />
            <tx:method name="find*" propagation="SUPPORTS" />
            <tx:method name="load*" propagation="SUPPORTS" />
            <tx:method name="search*" propagation="SUPPORTS" />
            <tx:method name="datagrid*" propagation="SUPPORTS" />


            <tx:method name="*" propagation="SUPPORTS" />
        </tx:attributes>
    </tx:advice>
    
</bean> 原来跑这里来了

不知道大家看出什么原因没有，似乎都很正确，没毛病。

说重点，我说过不是位置错了就是字符错了。

其实就是我方的位置错误了，我不小心写<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">这个的时候忘记及时把结束</bean>加上，然后等我把接下来的

<aop:config>
<aop:pointcut id="transactionPointcut"
expression="execution(* com.zou.test.service..*Impl.*(..))" />
<aop:advisor pointcut-ref="transactionPointcut"
advice-ref="transactionAdvice" />
</aop:config>

<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="append*" propagation="REQUIRED" />
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="modify*" propagation="REQUIRED" />
<tx:method name="edit*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="remove*" propagation="REQUIRED" />
<tx:method name="repair" propagation="REQUIRED" />
<tx:method name="delAndRepair" propagation="REQUIRED" />


<tx:method name="get*" propagation="SUPPORTS" />
<tx:method name="find*" propagation="SUPPORTS" />
<tx:method name="load*" propagation="SUPPORTS" />
<tx:method name="search*" propagation="SUPPORTS" />
<tx:method name="datagrid*" propagation="SUPPORTS" />


<tx:method name="*" propagation="SUPPORTS" />
</tx:attributes>
</tx:advice>

这些代码写完才加上这个</bean>，当然这样也没有报错，所以我没注意，等启动时候报错了，我当时网上疯查，没找到我想要的。后来我就把原版的复制过来，启动就没报错了，我于是不服，我就是要弄个明白，后来这样仔细一对比，才发现我的位置放得不对。要把中间那些代码从<aop:config>开始放到<bean>外面，不要包在里面。希望我这个低级错误能帮到你们。

 

正确配置代码：

<bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>---结束的</bean>          之前错误的原因</bean>在最下面。
    <aop:config>
        <aop:pointcut id="transactionPointcut"
            expression="execution(* com.zou.test.service..*Impl.*(..))" />
        <aop:advisor pointcut-ref="transactionPointcut"
            advice-ref="transactionAdvice" />
    </aop:config>

    <tx:advice id="transactionAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="append*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="modify*" propagation="REQUIRED" />
            <tx:method name="edit*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="remove*" propagation="REQUIRED" />
            <tx:method name="repair" propagation="REQUIRED" />
            <tx:method name="delAndRepair" propagation="REQUIRED" />

            <tx:method name="get*" propagation="SUPPORTS" />
            <tx:method name="find*" propagation="SUPPORTS" />
            <tx:method name="load*" propagation="SUPPORTS" />
            <tx:method name="search*" propagation="SUPPORTS" />
            <tx:method name="datagrid*" propagation="SUPPORTS" />

            <tx:method name="*" propagation="SUPPORTS" />
        </tx:attributes>
