title: Dependency injection in a CommandLineRunner failed
body: <p>I would like to develop a "batch" with Spring Boot. I have a class that implements a <code>CommandLineRunner</code> who need a <code>@Service</code> class.</p>
  
  <p>Here is the code :</p>
  
  <pre><code>@SpringBootApplication
  public class CarmindBatch implements CommandLineRunner {
  
      @Inject
      private VehicleDataBatchService vehicleDataBatchService;
  
      @Override
      public void run(String... args) {
  
          vehicleDataBatchService.start(args[0]);
      }
  
      public static void main(String[] args) {
  
          SpringApplication.run(CarmindBatch.class, args);
      }
  }
  </code></pre>
  
  <p>And the service :</p>
  
  <pre><code>@Service
  public class DefaultVehicleDataBatchService implements VehicleDataBatchService {
  
      @Inject
      private VehicleDataRepository vehicleDataRepository;
  
      @Inject
      private Mapper mapper;
  
      @Override
      public void start(String path) {
  
          // Convert a file to a list of beans and put them in database...
      }
  
  }
  </code></pre>
  
  <p>My problem is that a <code>BeanCreationException</code> occured when I launch <code>CarmindBatch</code> but it work well when I try with a JUnit test who inject <code>VehicleDataBatchService</code>.</p>
  
  <p>The stack trace :</p>
  
  <pre><code>org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'carmindBatch': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private fr.carmind.api.service.batch.VehicleDataBatchService fr.carmind.api.batch.CarmindBatch.vehicleDataBatchService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [fr.carmind.api.service.batch.VehicleDataBatchService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
