Springboot Integrated Quartz Dynamic Timing task

Springboot comes with schedule

The legacy of Springboot less XML configuration, which natively supports multiple timing tasks such as expressions
Note that when the program starts, add @EnableScheduling

@Scheduled (cron= "0/5 * * * * *?")
    public void Job () {
        System.out.println ("Executes every five Seconds");
    }

Why to use quartz

Quartz is easier to manage in multi-tasking situations, enabling dynamic configuration
Execution-time expression:

An example of an expression:
Integrated Quartz

How to build Springboot no longer elaborate on the official website and online tutorials a lot.

Maven Dependency

<dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactid>quartz</ artifactid>
            <version>2.2.1</version>
        </dependency>

Test Job Class
SCHEDULERQUARTZJOB1 and SCHEDULERQUARTZJOB2 codes are pretty much not listed.

Package com.yvan.quartz.job;

Import Org.quartz.Job;
Import Org.quartz.JobExecutionContext;
Import org.quartz.JobExecutionException;
/**
 * Implementation of the Job interface
 * @author Yvan * * */Public
class SchedulerQuartzJob1 implements job{
    private void before () {
        System.out.println ("task Start Execution");
    }

    @Override public
    void execute (jobexecutioncontext arg0) throws Jobexecutionexception {
        before ();
        System.out.println ("Start:" +system.currenttimemillis ());
        TODO Business
        System.out.println ("End:" +system.currenttimemillis ());
        After ();
    }

    private void After () {
        System.out.println ("task Start Execution");
    }

}

Task Invocation Processing
Split it into two partial instantiation jobs, adding task triggers to the Task Scheduler

    private void StartJob1 (Scheduler Scheduler) throws Schedulerexception {//Jobbuilder instances are built by Jobdetail, Jobdetail Specifies that only instances that implement the job interface//Jobdetail are specific job instances jobdetail Jobdetail = Jobbuilder.newjob (schedulerquartzjob1.class). W
        Ithidentity ("Job1", "group1"). Build ();
        Build a trigger based on an expression cronschedulebuilder Cronschedulebuilder = Cronschedulebuilder.cronschedule ("0/5 * * * *?"); Crontrigger expression trigger inherits from Trigger//Triggerbuilder used to build the trigger instance crontrigger Crontrigger = triggerbuilder.new
        Trigger (). Withidentity ("Job1", "group1"). Withschedule (Cronschedulebuilder). build ();
    Scheduler.schedulejob (Jobdetail, Crontrigger); } private void StartJob2 (Scheduler Scheduler) throws Schedulerexception {Jobdetail Jobdetail = jobbuilder.ne
        Wjob (Schedulerquartzjob2.class). Withidentity ("Job2", "group2"). Build ();
        Cronschedulebuilder Cronschedulebuilder = Cronschedulebuilder.cronschedule ("0 0/5 * * *?"); CroNtrigger Crontrigger = Triggerbuilder.newtrigger (). Withidentity ("Job2", "group2"). Withschedule (cronschedu
        Lebuilder). build ();
    Scheduler.schedulejob (Jobdetail, Crontrigger); }

Provide external methods for dynamic management tasks

    /** * Start performing All Tasks * * @throws schedulerexception */public void Startjob () throws Schedulerexcep
        tion {startJob1 (scheduler);
        STARTJOB2 (scheduler);

Scheduler Injection
This is done by listening to the spring container loading complete event, initiating the task call
Handing scheduler to spring initialization management

Encapsulation API
Here the API is designed to facilitate the dynamic management of the task, of course, depending on these interfaces can also do an interface to more intuitive operation of management tasks, this will not repeat.
