How to repeat:

@Controller
public class PagesController
{
	@Autowired
	protected ApplicationContext context;
	
	@PostConstruct
	public void postConstruct()
	{
		String beanName = "testBean";
		
		ConfigurableApplicationContext configContext = (ConfigurableApplicationContext) context;
		AutowireCapableBeanFactory beanFactory = configContext.getBeanFactory();
		BeanDefinitionRegistry registry = ((BeanDefinitionRegistry) beanFactory);
		
		GenericBeanDefinition beanDefinition = new GenericBeanDefinition();
		beanDefinition.setBeanClass(DefaultImpl.class);
		beanDefinition.setLazyInit(false);  
		beanDefinition.setAbstract(false);  
		beanDefinition.setAutowireCandidate(true); 
		registry.registerBeanDefinition(beanName, beanDefinition);
	}
}

Or like this.
serviceFactory.getByEntry is same as postConstruct() in previous example.

@Controller
public class PagesController
{
	protected DefaultService sampleService;

	@Autowired
	public void setService(ServiceFactory serviceFactory)
	{
		sampleService = serviceFactory.get("A");
	}
}

public class DefaultImpl
{
	private String Test;

	public String getTest()
	{
		return Test;
	}

	public void setTest(String test)
	{
		Test = test;
	}

}
