autowired object shows null even after @Configurable class

I have this class in which I want to access ILibraryRepository's autowired object. I make an object of this class using new AddLibraryProcessor(). So I used @Configurable but still the output shows null.

@Configurable(autowire = Autowire.BY_TYPE)
public class AddLibraryProcessor implements ICommandProcessor<AddLibrary> {

    @Autowired
    ILibraryRepository repository;

    @Override
    public IWebApiResponse Process(AddLibrary command) throws DomainProcessException{
        System.out.println(repository);
        return null;
    }
}

my pom.xml looks like :

Injection into non managed springs by @Configurable is not enabled by default. You have to enable this with e.g. adding @EnableSpringConfigured to any @Configuration annotated bean.

While reading 8.8.1 Using AspectJ to dependency inject domain objects with Spring you will note a further requirement:

For this to work the annotated types must be woven with the AspectJ weaver [..] or load-time weaving.
