How to Inject Spring Beans into Quartz Jobs

By default, Quartz does not recognize Spring beans configured in applicationContext.xml or with @Bean annotation. If we try to @Autowired these beans in Quartz Job or QuartzJobBean, we will get NullPointerException.

1. Injecting Spring ApplicationContext to QuartzJobBean

The solution is to inject Spring’s ApplicationContext instance to org.quartz.SchedulerContext which is available using org.quartz.JobExecutionContext parameter to executeInternal() method.

1.1. Inject ApplicationContext to SchedulerContext

This is typical SchedulerFactoryBean bean entry. Use setApplicationContextSchedulerContextKey() method. This method set the key of an ApplicationContext reference to expose in the SchedulerContext.

public SchedulerFactoryBean schedulerFactoryBean() throws IOException, SchedulerException 
  SchedulerFactoryBean scheduler = new SchedulerFactoryBean();
  scheduler.setTriggers(jobOneTrigger(), jobTwoTrigger());
  scheduler.setJobDetails(jobOneDetail(), jobTwoDetail());
  return scheduler;

1.2. Access Injected Beans in QuartzJobBean

Now, all you need to do is – get applicationContext reference and start fetching beans as per your need.

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.JobParametersBuilder;
import org.springframework.batch.core.configuration.JobLocator;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;
public class CustomQuartzJob extends QuartzJobBean {
  private String jobName;
  private JobLauncher jobLauncher;
  private JobLocator jobLocator;
  public String getJobName() {
    return jobName;
  public void setJobName(String jobName) {
    this.jobName = jobName;
  protected void executeInternal(JobExecutionContext context) throws JobExecutionException 
      ApplicationContext applicationContext = (ApplicationContext) 
      jobLocator = (JobLocator) applicationContext.getBean(JobLocator.class);
      jobLauncher = (JobLauncher) applicationContext.getBean(JobLauncher.class);
      Job job = jobLocator.getJob(jobName);
      JobParameters params = new JobParametersBuilder()
          .addString("JobID", String.valueOf(System.currentTimeMillis()))
          .toJobParameters();, params);
    catch (Exception e) 

Now when you run quartz job, you will get the jobLocator and jobLauncher instances in executeInternal() method.

2. Conclusion

In this tutorial, we learned to inject the Spring context beans into QuartzJobBean instance so we can get or set the quartz properties in the runtime.
