You can find an answer here. I can suggest using org.reflections You can take a look at it here Reflections reflections = new Reflections(“com.mycompany”); Set<Class<? extends MyInterface>> classes = reflections.getSubTypesOf(MyInterface.class);
There is another simpler solution. The job can be given an annotation of DisallowConcurrentExecution which prevents multiple concurrent instances running. See docs here. The link keeps breaking so here is the relevant sample. @DisallowConcurrentExecution public class ColorJob implements Job {
Quartz 1 If you change your class to implement StatefulJob instead of Job, Quartz will take care of this for you. From the StatefulJob javadoc: stateful jobs are not allowed to execute concurrently, which means new triggers that occur before the completion of the execute(xx) method will be delayed. StatefulJob extends Job and does not … Read more
In spring boot, you can use an application property directly! For example: @Scheduled(fixedDelayString = “${my.property.fixed.delay.seconds}000″) private void process() { // your impl here } Note that you can also have a default value in case the property isn’t defined, eg to have a default of “60” (seconds): @Scheduled(fixedDelayString = “${my.property.fixed.delay.seconds:60}000”) Other things I discovered: the … Read more
Did you already check all of those listed in Open Source Job Schedulers in Java: jcrontab Quartz Fulcrum Scheduler Essiembre J2EE Scheduler Gos4j Oddjob Job Scheduler JDRing jBatchEngine MyBatchFramework Super cron4j
Quartz is an order of magnitude more complex than Spring’s built in scheduler, including support for persistent, transactional and distributed jobs. It’s a bit of a pig, though, even with Spring’s API support. If all you need to is to execute methods on a bean every X seconds, or on a cron schedule, then @Scheduled … Read more
Begin the line with 0 0 * * 1,2,3,4,5 <user> <command>. The first fields are minutes and hours. In this case the command will run at midnight. The stars mean: for every day of the month, and for every month. The 1 to 5 specify the days. monday to friday. 6=saturday 0=sunday.
You can use this SpringBeanJobFactory to automatically autowire quartz objects using spring: import org.quartz.spi.TriggerFiredBundle; import org.springframework.beans.factory.config.AutowireCapableBeanFactory; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.scheduling.quartz.SpringBeanJobFactory; public final 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 { … Read more
TL;DR In Quartz 1, you may use this cron: 59 59 23 31 12 ? 2099 (last valid date). In Quartz 2, you may use this cron: 0 0 0 1 1 ? 2200 Using an expression far in the future Made some quick tests using org.quartz.CronExpression. String exp = “0 0 0 1 1 … Read more
