Spring ActiveProfiles injection question

gistfile1.java

// Question: Can you do something like this without using interface-based injection?

@RunWith(SpringJUnit4ClassRunner.class)
@ActiveProfiles("test")
public class FakeDownloadUtilTest extends BaseTest {
    @Autowired
    DownloadUtil downloadUtil;

    @Test
    public void testFaked() {
        downloadUtil.downloadImage("asdf"); // returns null rather than throwing a RuntimeException
    }
}


//------

import org.springframework.stereotype.Component;

@Component
public class DownloadUtil extends DownloadUtil {
	public String downloadImage(String url) throws Exception {
		return null
	}
}

import org.springframework.context.annotation.Profile;
import org.springframework.stereotype.Component;

@Component
@Profile("test")
public class DownloadUtilFake extends DownloadUtil {
	@Override
	public String downloadImage(String url) throws Exception {
		throw new RuntimeException("Faked out!");
	}
