Spring 4 with quartz planner

Configuration

@Configuration @ComponentScan(basePackages="com.lokesh.tracker.integrations.jobs") public class QuartzConfig { public JobDetailFactoryBean dailySummary(){ JobDetailFactoryBean bean=new JobDetailFactoryBean(); bean.setJobClass(DailySummary.class); bean.setName("dailySummary"); bean.setGroup("dailySummaries"); return bean; } public CronTriggerFactoryBean dailySummarytrigger(){ CronTriggerFactoryBean bean=new CronTriggerFactoryBean(); bean.setJobDetail(dailySummary().getObject()); bean.setStartDelay(5000); bean.setBeanName("dailySummarytrigger"); bean.setGroup("dailySummaries"); bean.setCronExpression("0 0/1 * 1/1 * ? *"); return bean; } @Bean public SchedulerFactoryBean schedulerFactoryBean() { SchedulerFactoryBean scheduler = new SchedulerFactoryBean(); scheduler.setTriggers(dailySummarytrigger().getObject()); return scheduler; } }

Job

 @DisallowConcurrentExecution public class DailySummary extends QuartzJobBean{ @Override protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException { System.out.println("hello"); } }

Can some identify my mistakes. I use quartz for the first time. therefore, I could not understand what he was saying in error. In this example, I want to run the daily summmary class with quartz.

You must annotate the annotation dailySummarytrigger , dailySummary with the annotation @Bean . They are complete Spring beans, and there is post-processing that occurs before these beans are fully implemented. You get around them without commenting on them using @Bean

Instead of this configuration, you should use the @Scheduled annotation from spring.

Check out this documentation: http://docs.spring.io/spring/docs/4.0.0.RELEASE/spring-framework-reference/htmlsingle/#scheduling

All you have to do is create a Scheduler bean and then annotate the method you want to run at the scheduled time using @Scheduled(cron="0 0/1 * 1/1 * ? *")
