Quartz调度器在Spring批处理管理设置中不工作

Question

背景：我们有一些由spring batch管理的作业（作为启动应用程序）由cron job触发，我正在努力用quartz替换cron并添加spring batch admin来管理作业。

到目前为止，我能够通过spring batch管理控制台运行这些作业，当quartz试图启动作业执行时，问题就会发生。JobLauncher、JobLocator对象为空，这是autowired。请注意，我使用基于Java的配置，而不是XML。

@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);
        }

    }
}

从这里开始：将以下行添加到executeinternal方法的开头：

@Override
public void executeInternal(final JobExecutionContext context) throws JobExecutionException {
    // Adding this autowires everything as needed
    SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);    
    ...
}
