title: Quartz scheduler not working in Spring batch admin setup
body: <p>Background :
  We've some jobs managed by spring batch ( as boot application) triggered by cron job,  I'm working to replace cron with quartz and add spring batch admin to manage jobs.</p>
  
  <p>So far I'm able to run the jobs via spring batch admin console, issue happens when quartz attempts to fire a job execution.  JobLauncher, JobLocator objects are null which is autowired. Please note I use Java based configuration not XML.</p>
  
  <pre><code>@PersistJobDataAfterExecution
  @DisallowConcurrentExecution
  @Component
  @EnableBatchProcessing
  public class GatewayReconciliationQuartzJob extends QuartzJobBean {
  
      private static final String JOB_NAME = "GatewayReconciliationJob";
  
      @Autowired
      BatchJobLauncher batchJobLauncher;
  
      @Autowired
      private JobLocator jobLocator;
  
      @Autowired
      private JobLauncher jobLauncher;
  
      @Override
      protected void executeInternal(JobExecutionContext context) {
  
          try {
  
              if (null == jobLauncher) {
                  LOG.info("JobLauncher is null ");
              }
  
              if (null == jobLocator) {
                  LOG.info("jobLocator is null ");
              }
  
              LOG.info(String.format("Now really Starting Batch Job : %s", JOB_NAME));
  
              JobParametersBuilder builder = new JobParametersBuilder();
              builder.addDate("date", new Date());
  
              this.jobLauncher.run(this.jobLocator.getJob(JOB_NAME), builder.toJobParameters());
  
          } catch (JobExecutionAlreadyRunningException | JobInstanceAlreadyCompleteException | JobParametersInvalidException | NoSuchJobException | JobRestartException e) {
              LOG.error("Error executing job", e);
              throw new RuntimeException(e);
          }
  
      }
  }
