六、SpringBoot +Quartz整合多定时任务同时执行

本例中设置的是双任务每五秒钟同时执行一次，如果要设置多个任务，直接根据注释说明添加第三个任务即可，已经验证过，可以实现，因为刚开始接触Quartz，运行过程中会遇到什么问题目前不清楚，仅是多任务同时定时同时执行的实现

build.gradle中配置

compile 'org.quartz-scheduler:quartz:2.1.6'

第一个执行类RefreshTrbase

import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.stereotype.Component;

@Component
@EnableScheduling
public class RefreshTrbase {

    public void getTrbase(){
        System.out.println("1111111....");
    }
}

第二个执行类RefreshNews

import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.stereotype.Component;

@Component
@EnableScheduling
public class RefreshNews {
    public void getNews(){
        System.out.println("222222....");
    }
}

Quartz配置类

import org.quartz.JobDetail;
import org.quartz.Trigger;
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;
import org.springframework.scheduling.quartz.SimpleTriggerFactoryBean;

@Configuration
public class QuartzConfiguration {
    // 配置定时任务1
    @Bean(name = "firstJobDetail")
    public MethodInvokingJobDetailFactoryBean firstJobDetail(RefreshNews refreshNews) {
        MethodInvokingJobDetailFactoryBean jobDetail = new MethodInvokingJobDetailFactoryBean();
        // 是否并发执行
        jobDetail.setConcurrent(false);
        // 为需要执行的实体类对应的对象
        jobDetail.setTargetObject(refreshNews);
        // 需要执行的方法
        jobDetail.setTargetMethod("getNews");
        return jobDetail;
    }


    // 配置触发器1
    @Bean(name = "firstTrigger")
    public SimpleTriggerFactoryBean firstTrigger(JobDetail firstJobDetail) {
        SimpleTriggerFactoryBean trigger = new SimpleTriggerFactoryBean();
        trigger.setJobDetail(firstJobDetail);
        // 设置任务启动延迟
        trigger.setStartDelay(0);
        // 设置定时任务启动时间
        trigger.setStartTime(new Date(DateUtil.getNowTimeInMillis()));
        // 每5秒执行一次
        trigger.setRepeatInterval(5000);
        return trigger;
    }

    // 配置定时任务2
    @Bean(name = "secondJobDetail")
    public MethodInvokingJobDetailFactoryBean secondJobDetail(RefreshTrbase refreshTrbase) {
        MethodInvokingJobDetailFactoryBean jobDetail = new MethodInvokingJobDetailFactoryBean();
        // 是否并发执行
        jobDetail.setConcurrent(true);
        // 为需要执行的实体类对应的对象
        jobDetail.setTargetObject(refreshTrbase);
        // 需要执行的方法
        jobDetail.setTargetMethod("getTrbase");
        return jobDetail;
    }

    // 配置触发器2
    @Bean(name = "secondTrigger")
    public SimpleTriggerFactoryBean secondTrigger(JobDetail secondJobDetail) {
        SimpleTriggerFactoryBean trigger = new SimpleTriggerFactoryBean();
        trigger.setJobDetail(secondJobDetail);
        // 设置定时任务启动时间
        trigger.setStartTime(new Date(DateUtil.getNowTimeInMillis()));
        // cron表达式
        trigger.setRepeatInterval(5000);
        return trigger;
    }

    // 配置Scheduler
    @Bean(name = "scheduler")
    public SchedulerFactoryBean schedulerFactory(Trigger firstTrigger, Trigger secondTrigger) {
        SchedulerFactoryBean bean = new SchedulerFactoryBean();
        // 延时启动，应用启动1秒后
        bean.setStartupDelay(1);
        // 注册触发器
        bean.setTriggers(firstTrigger,secondTrigger);
        return bean;
    }
}

以上已经实现两种任务每5s执行一次，若要添加多种任务则

第三个任务Hehe

import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.stereotype.Component;

@Component
@EnableScheduling
public class Hehe {
    public void getHehe(){
        System.out.println("获取呵呵....");
    }
}

QuartzConfiguration中修改如下

// 配置定时任务3
    @Bean(name = "thirdJobDetail")
    public MethodInvokingJobDetailFactoryBean thirdJobDetail(Hehe hehe) {
        MethodInvokingJobDetailFactoryBean jobDetail = new MethodInvokingJobDetailFactoryBean();
        // 是否并发执行
        jobDetail.setConcurrent(true);
        // 为需要执行的实体类对应的对象
        jobDetail.setTargetObject(hehe);
        // 需要执行的方法
        jobDetail.setTargetMethod("getHehe");
        return jobDetail;
    }

    // 配置触发器3
    @Bean(name = "thirdTrigger")
    public SimpleTriggerFactoryBean thirdTrigger(JobDetail thirdJobDetail) {
        SimpleTriggerFactoryBean trigger = new SimpleTriggerFactoryBean();
        trigger.setJobDetail(thirdJobDetail);
        // cron表达式
        trigger.setRepeatInterval(5000);
        return trigger;
    }

    // 配置Scheduler
    @Bean(name = "scheduler")
    public SchedulerFactoryBean schedulerFactory(Trigger firstTrigger, Trigger secondTrigger, Trigger thirdTrigger) {
        SchedulerFactoryBean bean = new SchedulerFactoryBean();
        // 延时启动，应用启动1秒后
        bean.setStartupDelay(1);
        // 注册触发器
        bean.setTriggers(firstTrigger,secondTrigger,thirdTrigger);
        return bean;
    }

 执行结果：打印内容自己设置测试

说明： 

       以上代码是间隔时间启动定时任务，如果要在固定时间(比如每周一九点执行)，则修改以上代码设置按以下进行修改，以下代码是每一分钟执行一次

    // 配置触发器2
    @Bean(name = "secondTrigger")
    public CronTriggerFactoryBean secondTrigger(JobDetail secondJobDetail) {
        CronTriggerFactoryBean trigger = new CronTriggerFactoryBean();
        trigger.setJobDetail(secondJobDetail);
        // 设置任务启动延迟
//      trigger.setStartDelay(0);
//      trigger.setStartTime(new Date(DateUtil.getCurrentWeekTimeInMillis()));
        trigger.setStartTime(new Date(DateUtil.getNowTimeInMillis()));
        // cron表达式(设置间隔60s) 7天(d)=604800000毫秒(ms)
        trigger.setCronExpression("0 * * * * ?");
        return trigger;
    }
