Using annotations, I have only one line in the spring's
applicationContext.xml --
<context:component-scan base-package="packagename" />
Services are tagged with @Service, Daos are tagged with
@Component("xxxDaoImpl"), Wicket web pages have @SpringBean
(name="<serviceName>")
Within the ServiceImpl, the Daos are tagged with @Autowired.
No other xml config, setter, getter for daos etc.
Works like a charm.
