Springboot+quartz基本使用

引入依赖

        
            org.springframework.boot
            spring-boot-starter-quartz
            2.6.7
        

添加执行任务的实体类

package com.zhao.quartz;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import java.util.Date;

public class MyJob implements Job {

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println(new Date()+"_____开始执行");
    }
}

开始调度代码

package com.zhao.quartz;

import cn.hutool.core.date.DateUtil;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.Date;

@Service
public class TestJob {

    @Autowired
    private Scheduler scheduler;

    public void startJob(){
        JobBuilder jobBuilder = JobBuilder.newJob(MyJob.class).withIdentity(MyJob.class.getName() + "_1", MyJob.class.getName()).usingJobData("jobDetail", "jobDetail");
        JobDetail jobDetail = jobBuilder.build();
        CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("0/5 * * * * ? *").withMisfireHandlingInstructionDoNothing();
        CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(MyJob.class.getName() + "_1", MyJob.class.getName())
                .usingJobData("trigger", "trigger")
                .startAt(DateUtil.beginOfDay(DateUtil.offsetDay(new Date(), 1)))
                .endAt(DateUtil.endOfDay(DateUtil.offsetDay(new Date(), 1)))
                .withSchedule(cronScheduleBuilder)
                .build();
        try {
            scheduler.scheduleJob(jobDetail,trigger);
            System.out.println("任务:"+jobDetail.getKey()+"__执行成功");
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }
}
