创建job类

@Component
public class Job {
    public void execute(){
        System.out.println("随便写点");
    }
}

Quartz配置类

@Configuration
public class QuartzConfig {

    /**
     * 做啥事儿
     * @param job
     * @return
     */
    @Bean
    public MethodInvokingJobDetailFactoryBean methodInvokingJobDetailFactoryBean(Job job){
        MethodInvokingJobDetailFactoryBean jobDetailFactoryBean = new MethodInvokingJobDetailFactoryBean();
        jobDetailFactoryBean.setTargetObject(job);
        jobDetailFactoryBean.setTargetMethod("execute");
        return jobDetailFactoryBean;
    }

    /**
     * 啥时候做
     * @param jobDetailFactoryBean
     * @return
     */
    @Bean
    public CronTriggerFactoryBean cronTriggerFactoryBean(MethodInvokingJobDetailFactoryBean jobDetailFactoryBean){
        CronTriggerFactoryBean cronTriggerFactoryBean = new CronTriggerFactoryBean();
        cronTriggerFactoryBean.setCronExpression("*/1 * * * * ?");
        cronTriggerFactoryBean.setJobDetail(jobDetailFactoryBean.getObject());
        return cronTriggerFactoryBean;
    }

    /**
     * 啥时候做啥事儿
     * @param triggerFactoryBean
     * @return
     */
    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(CronTriggerFactoryBean triggerFactoryBean){
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
        schedulerFactoryBean.setTriggers(triggerFactoryBean.getObject());
        return schedulerFactoryBean;
    }
}
