SpringQuartz Kullanımı Job Yaratma

Giriş

Açıklaması şöyle

Job — An interface to be implemented by components that we wish to have executed. It has a single method called execute() on which we need to provide the details to be performed by the Job

Job iki şekilde kodlanabilir

1. Quartz projesinin Job arayüzünden kalıtılır

2. Spring' ait QuartzJobBean sınıfından  kalıtılır

Job Arayüzü

Örnek

Şöyle yaparız

public class FileDeletionJob implements Job {

  @Override
  public void execute(JobExecutionContext jobExecutionContext)
     throws JobExecutionException {
    String regex = jobExecutionContext.getJobDetail()
      .getJobDataMap()
      .getString("regex");
    File folder = new File(jobExecutionContext.getJobDetail()
                                              .getJobDataMap()
                                              .getString("path"));
    File[] files = folder.listFiles();

    Function<File, Boolean> regexMatcher = (file) -> Pattern.compile(regex)
      .matcher(file.getName()).find();

    System.out.println("#####Deleting Files#####");
    Arrays.stream(files).filter(regexMatcher::apply)
      .peek(System.out::println)
      .forEach(File::delete);
    System.out.println("#####Done#####");
  }
}

2. Spring QuartzJobBean Sınıfı

Açıklaması şöyle

Spring Boot provides a wrapper around Quartz Scheduler’s Job interface called QuartzJobBean. This allows you to create Quartz Jobs as Spring beans where you can autowire other beans.

Örnek

Şöyle yaparız

import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.springframework.scheduling.quartz.QuartzJobBean;

@Component
public class EmailJob extends QuartzJobBean {

  @Override
  protected void executeInternal(JobExecutionContext jobExecutionContext)
  throws JobExecutionException {
    logger.info("Executing Job with key {}", jobExecutionContext.getJobDetail().getKey());
    JobDataMap jobDataMap = jobExecutionContext.getMergedJobDataMap();
    ...
  }
}
