springboot整合quartz配置多任务

版权声明：随便转, 记得给个链接过来哦 https://blog.csdn.net/wk52525/article/details/79100973

看了另外一个篇在springboot中使用java类配置quartz的博客, 但是没有多任务的配置。 在这里写一个配置quartz多任务的demo, 使用两个任务, 使用SimpleTrigger和CronTrigger两种触发器, 最后一起注册到Scheduler中

关于quartz 定时方面的配置请另外百度。

• maven依赖

    <dependency>
        <groupId>org.quartz-scheduler</groupId>
        <artifactId>quartz</artifactId>
        <version>2.2.1</version>
    </dependency>
    <dependency>  
        <groupId>org.springframework.boot</groupId>  
        <artifactId>spring-boot-starter-test</artifactId>  
        <scope>test</scope>  
    </dependency>

• 任务类1

package top.kylewang.bos.quartz;

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

@Component
@EnableScheduling
public class FirstJob{

    public void task(){
        System.out.println("任务1执行....");
    }
}

• 任务类2

package top.kylewang.bos.quartz;

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

@Component
@EnableScheduling
public class SecondJob{

    public void task(){
        System.out.println("任务2执行....");
    }
}

• 使用java配置 (无需额外的yml或properties配置)

package top.kylewang.quartz;
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.MethodInvokingJobDetailFactoryBean;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import org.springframework.scheduling.quartz.SimpleTriggerFactoryBean;
import org.springframework.scheduling.quartz.CornTriggerFactoryBean;
import top.kylewang.bos.quartz.FirstJob ;
import top.kylewang.bos.quartz.SecondJob;


@Configuration
public class QuartzConfiguration {

    // 配置定时任务1
    @Bean(name = "firstJobDetail")
    public MethodInvokingJobDetailFactoryBean firstJobDetail(FirstJob firstJob) {
        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(firstJob);
        // 需要执行的方法
        jobDetail.setTargetMethod("task");
        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);
        // 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(SecondJob secondJob) {
        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(secondJob);
        // 需要执行的方法
        jobDetail.setTargetMethod("task");
        return jobDetail;
    }

    // 配置触发器2
    @Bean(name = "secondTrigger")
    public CronTriggerFactoryBean secondTrigger(JobDetail secondJobDetail) {
        CronTriggerFactoryBean trigger = new CronTriggerFactoryBean();
        trigger.setJobDetail(secondJobDetail.getObject()); 
        // cron表达式 
        trigger.setCronExpression("0 30 20 * * ?");
        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;
    }  
}
