How do I enable @Required Annotation in JavaConfig?

[JavaGeek_Boston]

Hello,
I'm trying to port an existing application to JavaConfig. How do I enable the @Required annotation? In XML, I did so via the <context:annotation-config/> tag. My code is:

@ContextConfiguration(locations = "mypackage.ApplicationConfig", loader = JavaConfigContextLoader.class)
public class ReplicatedStoreTest extends AbstractTestNGSpringContextTests{

	@Test
	public void test() {
		Assert.assertNotNull(config);
	}
	
	@Autowired
	StartupParameters config;
}

It's injecting properly into the config object, but ignoring the @Required in StartupParameters

Thanks in Advance,
