#Autowired does not work with #Configurable - spring

Question

I am trying to do an image upload API. I have a ImageUpload task as follows,
#Component
#Configurable(preConstruction = true)
#Scope(BeanDefinition.SCOPE_PROTOTYPE)
public class ImageUploadTask implements Callable<JSONObject> {
#Autowired
private ImageUploadService imageUploadService;
#Override
public JSONObject call() throws Exception {
....
//Upload image via `imageUploadService`
imageUploadService.getService().path('...').post('...'); // Getting null pointer here for imageUploadService which is a WebTarget
}
}
The ImageUploadService looks like the below,
#Component
public class ImageUploadService {
#Inject
#EndPoint(name="imageservice") //Custom annotation, battle tested and works well for all other services
private WebTarget imageservice;
public WebTarget getService() {
return imageservice;
}
}
Here is the spring boot application class,
#ComponentScan
#EnableSpringConfigured
#EnableLoadTimeWeaving(aspectjWeaving=EnableLoadTimeWeaving.AspectJWeaving.ENABLED)
#EnableAutoConfiguration
public class ImageApplication extends SpringBootServletInitializer {
#Bean
public InstrumentationLoadTimeWeaver loadTimeWeaver() throws Throwable {
InstrumentationLoadTimeWeaver loadTimeWeaver = new InstrumentationLoadTimeWeaver();
return loadTimeWeaver;
}
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
super.onStartup(servletContext);
servletContext.addListener(new RequestContextListener());
}
public static void main(String[] args) throws IOException {
SpringApplication.run(ImageApplication.class);
}
}
Additional information :
Spring version of dependencies are at 4.2.5.RELEASE
pom.xml has dependencies added for spring-aspects and
spring-instrument
I am getting a NullPointerException in ImageUploadTask. My suspicion is that #Autowired doesn't work as expected.
Why wouldn't work and how do I fix this?
Is it mandatory to use #Autowired only when I use #Conigurable, why not use #Inject? (though I tried it and getting same NPE)

Answer 1

By default the autowiring for the #Configurable is off i.e. Autowire.NO beacuse of which the imageUploadService is null
Thus update the code to explicity enable it either as BY_NAME or BY_TYPE as below.
#Component
#Configurable(preConstruction = true, autowire = Autowire.BY_NAME)
#Scope(BeanDefinition.SCOPE_PROTOTYPE)
public class ImageUploadTask implements Callable<JSONObject> { .... }
Rest of the configuration viz. enabling load time weaving seems fine.
Also regarding #Inject annotation have a look here which pretty much explains the difference (or similarity perhaps)
