The most commonly used timed task framework is Quartz, and Spring also integrates the Quartz framework. Quartz supports not only single instance mode but also distributed mode. This article mainly introduces Quartz, the basic Quartz integration case book, and the realization of database-based distributed task management and control job life cycle. @pdai

Prepare knowledge points

Requires knowledge of commonly used Quartz frameworks.

What is Quartz

Source Baidu Encyclopedia , official website address: http://www.quartz-scheduler.org/

Quartz is another open source project of the OpenSymphony open source organization in the field of Job scheduling. It can be combined with J2EE and J2SE applications or used alone. Quartz can be used to create simple or complex programs that run ten, hundreds, or even tens of thousands of Jobs. Jobs can be made into standard Java components or EJBs.

Its characteristics are as follows

  • Pure java implementation, can run as a standalone application or embedded in another standalone application
  • Powerful scheduling function, Spring's default scheduling framework, flexible and configurable;
  • Job persistence, scheduling environment persistence mechanism, can save and restore the scheduling scene. System shutdown data will not be lost; flexible application mode, can arbitrarily define trigger scheduling schedule, support various combinations of tasks and scheduling, component listeners, various plug-ins, thread pools and other functions, multiple storage methods, etc.;
  • Distributed and clustered capabilities, can be instantiated, each node in a Quartz cluster is used as an independent Quartz, through the same database table to perceive another Quartz application

Quartz Architecture

  • Job represents a job, the specific content to be executed.
  • JobDetail represents a specific executable scheduler, Job is the content to be executed by the executable scheduler, and JobDetail also includes the task scheduling scheme and strategy.
  • Trigger represents the configuration of a scheduling parameter, when to tune it.
  • Scheduler represents a scheduling container, and multiple JobDetails and Triggers can be registered in a scheduling container. When Trigger is combined with JobDetail, it can be scheduled by Scheduler container.

Note: The above picture comes from https://www.cnblogs.com/jijm123/p/14240320.html

What is Quartz Persistence

  • Why Persistence ?

When the program is suddenly interrupted, such as power failure, when the memory exceeds, it is likely to cause the loss of tasks. The scheduling information can be stored in the database for persistence. When the program is interrupted and restarted, the data before the interruption will still be retained and the execution will continue instead of restarting.

  • Quartz provides two persistence methods

Quartz offers two basic job storage types:

  1. RAMJobStore

By default, Quartz keeps the running information of task scheduling in memory. This method provides the best performance because the data access in memory is the fastest. The downside is the lack of data persistence. When the program stops on its way or the system crashes, all running information is lost.

  1. JobStoreTX

All task information will be saved in the database, which can control things, and if the application server is shut down or restarted, the task information will not be lost, and tasks that fail to execute due to server shutdown or restart can be recovered.

Implementation case - single instance method

This example will show the way quartz implements a single instance.
  • Introduce POM dependencies
 <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
  • Define Job

You only need to inherit QuartzJobBean and overload the executeInternal method to define your own Job execution logic.

 @Slf4j
public class HelloJob extends QuartzJobBean {

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        // get parameters
        context.getJobDetail().getJobDataMap().forEach(
                (k, v) -> log.info("param, key:{}, value:{}", k, v)
        );
        // your logics
        log.info("Hello Job执行时间: " + new Date());
    }
}
  • Configure Job

JobDetail, Trigger, Schedule (CronScheduleBuilder is used here)

 /**
 * @author pdai
 */
@Configuration
public class QuartzConfig {

    @Bean("helloJob")
    public JobDetail helloJobDetail() {
        return JobBuilder.newJob(HelloJob.class)
                .withIdentity("DateTimeJob")
                .usingJobData("msg", "Hello Quartz")
                .storeDurably()//即使没有Trigger关联时,也不需要删除该JobDetail
                .build();
    }

    @Bean
    public Trigger printTimeJobTrigger() {
        // 每秒执行一次
        CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("0/1 * * * * ?");
        return TriggerBuilder.newTrigger()
                .forJob(helloJobDetail())
                .withIdentity("quartzTaskService")
                .withSchedule(cronScheduleBuilder)
                .build();
    }
}
