java - spring配置多个数据源bug

Question

<bean id="dataSource" class="com.wacai.datamigration.configs.DynamicDataSource">

    <property name="targetDataSources">
        <!-- 制定lookupKey和与之对应的数据源 -->
        <map key-type="java.lang.String">
            <entry key="donghuaDataSource" value-ref="donghuaDataSource"/>
            <entry key="adanosDataSource" value-ref="adanosDataSource"/>
        </map>
    </property>
    <!-- 指定默认数据源 -->
    <property name="defaultTargetDataSource" ref="donghuaDataSource"/>
</bean>

报错如下：

你所展示的这个XML片段没有问题，看起来你的问题好像是value-ref="donghuaDataSource"，建议把配置文件补全。
