quartz简单实现多任务并发

package com.scan.xxx.config.quartz;

import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.CronTriggerFactoryBean;
import org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
@Slf4j
@Configuration
public class QuartzConfig {
    @Autowired
    private Scheduler scheduler;
    @Bean(name = "jobDetail")
    public MethodInvokingJobDetailFactoryBean detailFactoryBean(SchedulerTask task){
        MethodInvokingJobDetailFactoryBean jobDetail = new MethodInvokingJobDetailFactoryBean();
        /*
         *  是否并发执行
         *  例如每5s执行一次任务，但是当前任务还没有执行完，就已经过了5s了，
         *  如果此处为true，则下一个任务会bing执行，如果此处为false，则下一个任务会等待上一个任务执行完后，再开始执行
         */
        jobDetail.setConcurrent(true);//设置并行

        jobDetail.setName("scheduler");// 设置任务的名字
        jobDetail.setGroup("scheduler_group");// 设置任务的分组，这些属性都可以存储在数据库中，在多任务的时候使用

        /*
         * 这两行代码表示执行task对象中的scheduleTest方法。定时执行的逻辑都在scheduleTest。
         */
        jobDetail.setTargetObject(task);

        jobDetail.setTargetMethod("start");
        return jobDetail;
    }

    @Bean(name = "jobTrigger")
    public CronTriggerFactoryBean cronJobTrigger(MethodInvokingJobDetailFactoryBean jobDetail) {
        CronTriggerFactoryBean tigger = new CronTriggerFactoryBean();
        tigger.setJobDetail(jobDetail.getObject());
        tigger.setCronExpression("0 0 12 * * ?");// 表示每天中午12点
        //tigger.set
        tigger.setName("myTigger");// trigger的name
        return tigger;

    }

    @Bean(name = "scheduler")
    public SchedulerFactoryBean schedulerFactory(Trigger cronJobTrigger) {
        SchedulerFactoryBean schedulerFactoryBean1 = new SchedulerFactoryBean();
        //设置是否任意一个已定义的Job会覆盖现在的Job。默认为false，即已定义的Job不会覆盖现有的Job。
        schedulerFactoryBean1.setOverwriteExistingJobs(true);
        // 延时启动，应用启动5秒后  ，定时器才开始启动
        schedulerFactoryBean1.setStartupDelay(5);
        // 注册定时触发器
        schedulerFactoryBean1.setTriggers(cronJobTrigger);
        return schedulerFactoryBean1;
    }
    //多任务时的Scheduler，动态设置Trigger。一个SchedulerFactoryBean可能会有多个Trigger
    @Bean(name = "multitaskScheduler")
    public SchedulerFactoryBean schedulerFactoryBean(){
        SchedulerFactoryBean bean = new SchedulerFactoryBean();
        return bean;
    }

    /**
     * 根据任务名任务组删除
     */


}

　　配置类

package com.scan.xxx.controller.quartz;

import com.scan.xxx.config.quartz.QuartzConfig;
import com.scan.xxx.config.quartz.Task1;
import com.scan.xxx.config.quartz.Task2;
import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.annotation.Resource;

@Slf4j
@Controller
public class QuartzController2 {
    @Resource(name = "multitaskScheduler")
    private Scheduler scheduler;
    @Autowired
    private QuartzConfig quartzConfig;

    JobDetail jobDetail;

    @ResponseBody
    @RequestMapping("/task1")
    public Object task1() throws SchedulerException {
        //配置定时任务对应的Job，这里执行的是ScheduledJob类中定时的方法
        jobDetail = JobBuilder
                .newJob(Task1.class)

                .withIdentity("job1", "group1")
                .build();
        CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule("0/11 * * * * ?");
        // 每3s执行一次
        CronTrigger cronTrigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "group1").withSchedule(scheduleBuilder).build();
        scheduler.scheduleJob(jobDetail, cronTrigger);

        return "任务1";
    }

    @ResponseBody
    @RequestMapping("/task2")
    public Object task2() throws SchedulerException {
        //配置定时任务对应的Job，这里执行的是ScheduledJob类中定时的方法
        jobDetail = JobBuilder.newJob(Task2.class).withIdentity("job2", "group1").build();
        CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule("0/6 * * * * ?");
        // 每3s执行一次
        CronTrigger cronTrigger = TriggerBuilder.newTrigger().withIdentity("trigger2", "group1").withSchedule(scheduleBuilder).build();
        scheduler.scheduleJob(jobDetail, cronTrigger);

        return "任务2";
    }

    @ResponseBody
    @RequestMapping("/taskDelete")
    public void taskDelete(String taskCode, String taskGroup) throws SchedulerException {
        //配置定时任务对应的Job，这里执行的是ScheduledJob类中定时的方法

        delete(taskCode, taskGroup);
    }

    public void delete(String taskCode, String taskGroup) throws SchedulerException {
        JobKey jobKey = new JobKey(taskCode, taskGroup);
        log.info(jobKey.getName());
        JobDetail jobDetail = scheduler.getJobDetail(jobKey);
        if (jobDetail == null) {
            log.info("不存在job");
            return;
        }
        log.info("删除" + jobKey.toString());
        scheduler.deleteJob(jobKey);
    }
}

实现类

 模拟2个业务类

package com.scan.xxx.config.quartz;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

import java.util.Date;

public class Task1 implements Job {


    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        String name = jobExecutionContext.getJobDetail().getKey().getName();
        System.out.println("1111执行"+name+new Date());
    }
}
