依赖注入~~同一个错误犯两遍就是煞笔

Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'RssService' defined in ServletContext resource
 [/WEB-INF/vbm_dao.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException:
 Invalid property 'rssDao' of bean class [gov.ict.mcg.vbm.services.impl.RssServiceImpl]: Bean property 'rssDao'
 is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'rssDao' of bean class

 Does the parameter type of the setter match the return type of the getter?

原因：
RssServiceImpl类中忘记添加dao的get set方法~~~
