spring 配置有关问题

spring 配置问题
<bean id="tawRmCommonfaultDetailMgr" parent="txProxyTemplate">
<property name="target">
<bean
class="com.boco.eoms.duty.mgr.impl.TawRmCommonfaultDetailMgrImpl>
<property name="tawRmCommonfaultDetailDao" ref="tawRmCommonfaultDetailDao" />
</bean>
</property>
</bean>
 
  <bean id="tawRmCommonfaultDetailDao" class="com.boco.eoms.duty.dao.jdbc.TawRmCommonfaultDetailDaoJDBC" autowire="byName"/> 这个就是配置
 在java中有tawRmCommonfaultDetailDao的get和set方法。但是出现如下错误
 Error creating bean with name 'tawRmCommonfaultDetailMgr' defined in 
  class path resource [config/applicationContext-duty.xml]: 
  Cannot create inner bean 'com.boco.eoms.duty.mgr.impl.TawRmCommonfaultDetailMgrImpl#fd1463'

Java code

[code=XML]<bean id="tawRmCommonfaultDetailMgr" parent="txProxyTemplate"><property name="target"></property></bean><bean class="com.boco.eoms.duty.mgr.impl.TawRmCommonfaultDetailMgrImpl><property name="tawRmCommonfaultDetailDao" ref="tawRmCommonfaultDetailDao" />    </bean>
------解决方案--------------------------------------------------------
XML code
<bean id="tawRmCommonfaultDetailMgr" parent="txProxyTemplate"><property name="target" 这里没有指明那个ref啊/></bean><bean class="com.boco.eoms.duty.mgr.impl.TawRmCommonfaultDetailMgrImpl><property name="tawRmCommonfaultDetailDao" ref="tawRmCommonfaultDetailDao" />    </bean>
