quartz是java裏頭定時任務的經典開源實現，這裏講述一下如何在springboot中集成quartz。html

maven

<dependency>
            <groupId>org.springframework</groupId>

內存版配置

org.quartz.scheduler.instanceName=spring-boot-quartz-demo
org.quartz.scheduler.instanceId=AUTO
org.quartz.threadPool.threadCount=5
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

quartz config

@Configuration
public class QuartzConfig {

    public static final String QUARTZ_PROPERTIES_PATH = "/quartz.properties";

    @Bean
    public JobFactory jobFactory(ApplicationContext applicationContext) {
        AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
        jobFactory.setApplicationContext(applicationContext);
        return jobFactory;
    }

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(JobFactory jobFactory) throws IOException {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setAutoStartup(true);
        factory.setJobFactory(jobFactory);
        factory.setQuartzProperties(quartzProperties());
        return factory;
    }

    @Bean
    public Properties quartzProperties() throws IOException {
        PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
        propertiesFactoryBean.setLocation(new ClassPathResource(QUARTZ_PROPERTIES_PATH));
        propertiesFactoryBean.afterPropertiesSet();
        return propertiesFactoryBean.getObject();
    }

    public static class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements
            ApplicationContextAware {

        private transient AutowireCapableBeanFactory beanFactory;

        @Override
        public void setApplicationContext(final ApplicationContext context) {
            beanFactory = context.getAutowireCapableBeanFactory();
        }

        @Override
        protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
            final Object job = super.createJobInstance(bundle);
            beanFactory.autowireBean(job);
            return job;
        }
    }
}

demo job

@PersistJobDataAfterExecution
@DisallowConcurrentExecution
public class DemoJob implements Job{

    private String jobArg;

    @Autowired
    DemoService demoService;

    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        demoService.hello(jobArg);
    }

    public void setJobArg(String jobArg) {
        this.jobArg = jobArg;
    }
}

註冊到quartz去調度java

@Autowired
    SchedulerFactoryBean schedulerFactoryBean;

    public void scheduleJobs() throws SchedulerException {
        Scheduler scheduler = schedulerFactoryBean.getScheduler();

        JobDataMap jobDataMap = new JobDataMap();
        jobDataMap.put("jobArg", "world");
        JobDetail jobDetail = JobBuilder.newJob(DemoJob.class)
                .setJobData(jobDataMap)
                .withDescription("demo")
                .withIdentity("demo-job", "demo-group")
                .build();

        Trigger trigger = TriggerBuilder.newTrigger()
                .forJob(jobDetail)
                .withSchedule(cronSchedule("0/5 * * * * ?"))
                .build();
        if(!scheduler.checkExists(JobKey.jobKey("demo-job","demo-group"))){
            scheduler.scheduleJob(jobDetail,trigger);
        }
        scheduler.start();
    }

使用postgres做爲持久層版本

設置數據源和數據管理器

@Bean
    public SchedulerFactoryBean schedulerFactoryBean(JobFactory jobFactory, DataSource dataSource, PlatformTransactionManager transactionManager) throws IOException {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setAutoStartup(true);
        factory.setJobFactory(jobFactory);
        factory.setQuartzProperties(quartzProperties());

        //jdbc store
        factory.setDataSource(dataSource);
        factory.setTransactionManager(transactionManager);

        return factory;
    }
