If you have a bean of type Class, it’s the same as everything else – with @Autowired / @Inject (and optionally @Qualifier)

How to create such a bean? Multiple ways:

• xml – using factory-method="forName" and constructor-arg passing java.lang.Class
• using a FactoryBean that produces Class objects
• java config

However, it is is a bit strange that you need a Class object as bean – you can’t inject any dependencies in it. Perhaps you can simply inject the class name (with @Value("${class.name}")) and then use Class.forName(..) in a @PostConstruct method.
