在构造函数上自动连线

Question

我经常看到在构造函数而不是变量本身上使用@Autowired注释：

@Service
public class AddressServiceImpl implements AddressService {

    private AddressRepository addressRepository;
    private UserRepository userRepository;

    @Autowired
    public AddressServiceImpl(AddressRepository addressRepository,
            UserRepository userRepository) {
        this.addressRepository = addressRepository;
        this.userRepository = userRepository;
    }
}

与下面的代码不同吗？

@Service
public class AddressServiceImpl implements AddressService {

    @Autowired
    private AddressRepository addressRepository;
    @Autowired
    private UserRepository userRepository;
}

谢谢
