Spring Framework Question

Hi,

I'm new to the Spring Framework.  I understand the basic concepts, but am
not familiar with the details regarding how to hook up dependencies.

For example, I see this in various classes:

@Inject DiskOfferingDao diskOfferingDao;


What did we have to do in Spring (ex. files to configure) so that the
proper runtime instance of DiskOfferingDao was instantiated and assigned to
diskOfferingDao?


Thanks!

Hi Mike,
You typically have a public interface for your DAO:
public interface InfobloxDao extends GenericDao<InfobloxDeviceVO, Long>{
....
}

Then an implementation:
public class InfobloxDaoImpl extends GenericDaoBase<InfobloxDeviceVO, Long>
     implements InfobloxDao {
...
}

This is a good link for the details of Database Access:
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Data+Access+Layer

The DataBase DAO is one of the Beans you register with Spring
componentContext.xml.in:  <bean id="InfobloxDaoImpl" class="org.apache.cloudstack.network.dao.InfobloxDaoImpl" />

Then at run time the call like the one you have below wires your application typically plugin to the plugin data base implementation:
@Inject
 InfobloxDao _infobloxDao;
