java - how to inject parent class property with spring annotation -

parent class this:

public class basedao{     private dbroute defaultdb;      public dbroute getdefaultdb()     {         return this.defaultdb;     }      public void setdefaultdb(dbroute defaultdb)     {         this.defaultdb = defaultdb;     } } 

i have create beans below:

<bean id="adsconfigdb" class="net.flyingfat.common.dbroute.config.dbroute">     <constructor-arg value="adsconfig" /> </bean>  <bean id="adsbizdatedb" class="net.flyingfat.common.dbroute.config.dbroute">     <constructor-arg value="adsbizdate" /> </bean> 

i want inject superclass property defaultdb in subclass through byname, not bytype, in subclass inject defaultdb using adsconfigdb or adsbizdatedb. there way spring annotations? tried autowired or resource constructor doesn't work. way, know can done using xml.

@qualifier annotation – annotation used avoid conflicts in bean mapping , need provide bean name used autowiring. way can avoid issues multiple beans defined same type. annotation works @autowired annotation. constructors multiple arguments, can use annotation argument names in method.

your code this..

@autowired @qualifier("adsconfig") private dbroute defaultdb;
