Quartz教程

** 1.导入依赖**

 <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-quartz</artifactId>
    </dependency>

2.配置类

package com.example.demoz.config;

import com.example.demoz.job.MyJob;
import org.quartz.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class QuartzConfig {

    @Bean
    public JobDetail quartzTestDetail() {
        JobDetail jobDetail = JobBuilder.newJob(MyJob.class)
                //添加认证信息
                .withIdentity("jobDetail", "quarts")
                .storeDurably(true)
                .build();
        return jobDetail;
    }
    /**
     * 创建触发器
     */
    @Bean
    public Trigger quartzTestJobTrigger() {
        //执行频率
        CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("*/5 * * * * ?");
        //创建触发器
        Trigger trigger = TriggerBuilder.newTrigger()
                .forJob(quartzTestDetail())
                .startNow()
                //添加认证信息
                .withIdentity("jobTrigger", "trigger")
                //添加执行规则
                .withSchedule(cronScheduleBuilder)

                .build();
        return trigger;
    }
}

3.job实现

package com.example.demoz.job;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class MyJob  extends QuartzJobBean {


    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        System.out.println("执行定时任务");
    }
}
