This article mainly introduces the relevant knowledge of "how spring boot integrates quartz to manage timing tasks through page operation". The editor shows you the operation process through an actual case. The method of operation is simple and fast, and it is practical. I hope this article "how to integrate spring boot quartz to achieve timing tasks through page operation management" can help you solve the problem.

Know a few key words before using it:

Job

By implementing the Job class, we write down what we want the timed task to do in the implementation method, and then give it to quartz to manage.

JobDetail

Job is only responsible for implementing specific tasks, so you also need to use JobDetail to store some basic information that describes Job.

Quartz JobBuilder

The builder-style API provided for constructing JobDetail entities. You can use it to build a JobDetail like this:

@ Bean

Public JobDetail jobDetail () {

Return JobBuilder.newJob (). OfType (SampleJob.class)

. StoreDurably ()

. WithIdentity ("Qrtz_Job_Detail")

. WithDescription ("Invoke Sample Job service..." )

. Build ()

}

Spring JobDetailFactoryBean

How to configure JobDetail in Spring:

@ Bean

Public JobDetailFactoryBean jobDetail () {

JobDetailFactoryBean jobDetailFactory = new JobDetailFactoryBean ()

JobDetailFactory.setJobClass (SampleJob.class)

JobDetailFactory.setDescription ("Invoke Sample Job service..." )

JobDetailFactory.setDurability (true)

Return jobDetailFactory

}

Trigger

Trigger, which represents the configuration of a scheduling parameter, when to schedule:

@ Bean

Public Trigger trigger (JobDetail job) {

Return TriggerBuilder.newTrigger (). ForJob (job)

. WithIdentity ("Qrtz_Trigger")

. WithDescription ("Sample trigger")

. WithSchedule (simpleSchedule (). RepeatForever (). WithIntervalInHours (1))

. Build ()

}

Scheduler

A scheduler, which registers a scheduler through Job and Trigger:

@ Bean

Public Scheduler scheduler (Trigger trigger, JobDetail job) {

StdSchedulerFactory factory = new StdSchedulerFactory ()

Factory.initialize (new ClassPathResource ("quartz.properties"). GetInputStream ()

Scheduler scheduler = factory.getScheduler ()

Scheduler.setJobFactory (springBeanJobFactory ())

Scheduler.scheduleJob (job, trigger)

Scheduler.start ()

Return scheduler

}

These are some of the concepts you need to know to use quartz, but to sum up there are only three things: job | jobDetail, trigger, and schedule. That is, tasks, triggers and schedulers. So we just have to instantiate them in code. And the task can be persisted to the database, which is convenient for us to operate all kinds of tasks.

Quartz automatically starts executing scheduled tasks in the executable state when the project starts, and can also support clustering.
