关于spring动态数据源AbstractRoutingDataSource的问题

配置是这样的：  
<bean id="dataSource" class="gxlu.omega.common.dbutil.DynamicDataSource">      
            <property name="targetDataSources">      
               <map key-type="java.lang.String">      
                  <entry key="0" value-ref="104_DS"/>   
                  <entry key="1" value-ref="12_DS"/>   
               </map>      
            </property>      
            <property name="defaultTargetDataSource" ref="104_DS"/>      
    </bean> 
weblogic也有配置相应的数据源，出的问题是下面的错误：org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in ServletContext resource [/WEB-INF/omega-war-beans.xml]: Cannot resolve reference to bean '104_DS' while setting bean property 'targetDataSources' with key [org.springframework.beans.factory.config.TypedStringValue@186e8cb]; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named '104_DS' is defined

数据源是定义了，为啥会找不到呢？不知道是不是哪里还有什么东西没有配置？有没有哪位大侠知道的啊，很急啊。。
