BeansException 发生：找不到名为“conslEngineDAO”的 bean 的 class

Question

THIS IS NOT FULL CODE AS I'M NOT THE ONE WHO WROTE IT, I'M JUST DEBUGGING IT.PLEASE LET ME KNOW IF I NEED TO ADD ANYTHING I'm trying to debug a standalone class called DroppedToCheckReportProcess.java for some other error, but now I'm getting this error and I can seem to figure out what is the issue. Any help would be appreciated. Am I missing something in Application-context or spring-bean file. Stacktrace at the end.

DroppedToCheckReportProcess.java

getBean() throws the error NoSuchBeanFound I've check other queries similar to this, but all says @Autowire is required, but it doesn't seem to work for me. This is a legacy code which is why it is not quite possible to have wrong code as I have fetched from latest git branch. It does not have a resource folder as well all the config files are in config folder.

public class DroppedToCheckReportProcess {
    public static void main(String[] args) {
    dtcRptProc.getBean();
    PayerTO payerTO = null;
    List reorigCheckPaymentList = new ArrayList();
    List dtpcRptRecList = new ArrayList();
    ArrayList fetchPayerList = (ArrayList) enrollDAO.fetchPayers();
    List uhcPayerList =  new ArrayList(enrollDAO.getPayerList());
    protected void getBean() {
        String strContext = "getBean()";
        logger.debug(strContext, "Start");
        try {
            String aContxt = BatchProperties.getInstance().getProperty("APPLICATION_CONTEXT");
            aContxt = aContxt + "_" + System.getProperty("eps.env") + ".xml";
            String sBeanCtx = BatchProperties.getInstance().getProperty("SPRING_BEANS");
            String[] configFiles = new String[] { aContxt, sBeanCtx };
            appContext = new ClassPathXmlApplicationContext(configFiles);
            enrollDAO = (EnrollmentDAO) appContext.getBean("enrollmentDAO");
            mPaymentDAO = (PaymentDAO) appContext.getBean("paymentDAO");
            mPayorDAO = (PayorDAO) appContext.getBean("payorDAO");
            logger.debug(strContext, "End");
        } catch (BeansException e) {
            logger.error(strContext, "BeansException occured :" + e.getMessage());
        } catch (Exception e) {
            e.printStackTrace();
            logger.error(strContext, "Exception occured :" + e.getMessage());
            System.exit(2);
        }
    }

Answer 1

Looks like you import the wrong class. The error message mentions:

com.uhg.optumHealth.batch.dao.impl.ConslEngineDAOImpl

the XML file:

com.batch.dao.impl.ConslEngineDAOImpl
