I am trying for so long but not able to understand why I am getting below error. I have tried all the possible solutions available on the internet.It is a standalone utility to insert the data in the database.
@Configuration
@ComponentScan({"aero.sita.gsl.ee.services.referencedata"})
public class CRDExporterApplication {
/**
* Logger: log
*/
final static Logger log = LogManager.getLogger(CRDExporterApplication.class);
public static void main(String[] args) throws java.text.ParseException {
ApplicationContext context =new AnnotationConfigApplicationContext(CRDExporterApplication.class);
log.info("main: Starting export execution");
CRDExporterController crdExporterController = context.getBean(CRDExporterController.class);
try {
//CRDExporterController crdExporterController = new CRDExporterController();
crdExporterController.referenceDataCRDGet();
log.info("main: Export Successful");
} catch (IOException | ParseException | SQLException e) {
log.error("Error: " + e);
}
}
}
Please find the controller class to call from the Application class.
@Component
public class CRDExporterController {
@Autowired
private CRDExporterService crdExporterService;
/**

final static Logger log = LogManager.getLogger(CRDExporterController.class);

log.info("referenceDataCRDGet: Reading property file process complete.");

//crdExporterService.exportCRD(eeProperties);
