• 编写job类

package com.ltf.shop.quartzdemo;import org.quartz.Job;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;public class HelloJob implements Job {    @Override    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {        System.out.println("hello word quartz");    }}

• 编写quartz定义类

package com.ltf.shop.quartzconfig;import com.ltf.shop.quartzdemo.HelloJob;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.scheduling.quartz.CronTriggerFactoryBean;import org.springframework.scheduling.quartz.JobDetailFactoryBean;import org.springframework.scheduling.quartz.SchedulerFactoryBean;@Configurationpublic class QuartzConfig {    /**     * 创建Job对象     */    @Bean    public JobDetailFactoryBean jobDetailFactoryBean()    {        JobDetailFactoryBean factory=new JobDetailFactoryBean();        factory.setJobClass(HelloJob.class);        return  factory;    }    /**     * 创建Job对象     *///    @Bean//    public SimpleTriggerFactoryBean simpleTriggerFactoryBean(JobDetailFactoryBean jobDetailFactoryBean)//    {//        SimpleTriggerFactoryBean simpleTriggerFactoryBean=new SimpleTriggerFactoryBean();//        //关联JobDetail对象//        simpleTriggerFactoryBean.setJobDetail(jobDetailFactoryBean.getObject());//        //设置执行的毫秒数//        simpleTriggerFactoryBean.setRepeatInterval(3000);//        simpleTriggerFactoryBean.setRepeatCount(15);//        return simpleTriggerFactoryBean;//    }//    /**//     * 创建scheduler对象//     *///    @Bean//    public SchedulerFactoryBean schedulerFactoryBean(SimpleTriggerFactoryBean simpleTriggerFactoryBean)//    {//        SchedulerFactoryBean schedulerFactoryBean=new SchedulerFactoryBean();//        schedulerFactoryBean.setTriggers(simpleTriggerFactoryBean.getObject());//        return schedulerFactoryBean;//    }    @Bean    public CronTriggerFactoryBean cronTriggerFactoryBean(JobDetailFactoryBean jobDetailFactoryBean)    {        CronTriggerFactoryBean cronTriggerFactoryBean=new CronTriggerFactoryBean();        cronTriggerFactoryBean.setJobDetail(jobDetailFactoryBean.getObject());        cronTriggerFactoryBean.setCronExpression("0/2 * * * * ?");        return cronTriggerFactoryBean;    }    @Bean    public SchedulerFactoryBean schedulerFactoryBean(CronTriggerFactoryBean cronTriggerFactoryBean)    {        SchedulerFactoryBean schedulerFactoryBean=new SchedulerFactoryBean();        schedulerFactoryBean.setTriggers(cronTriggerFactoryBean.getObject());        return schedulerFactoryBean;    }}
