5.Quartz配置：QuartzConfig.class
@Configuration
public class QuartzConfig {

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(){
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
        schedulerFactoryBean.setOverwriteExistingJobs(true);//覆盖已存在的任务
        schedulerFactoryBean.setStartupDelay(60);//延时60秒启动定时任务，避免系统未完全启动却开始执行定时任务的情况
        return schedulerFactoryBean;
    }

    // 创建schedule
    @Bean(name = "scheduler")
    public Scheduler scheduler() {
        return schedulerFactoryBean().getScheduler();
    }
}
6.实体：ScheduleJob.class，枚举：JobOperateEnum
@TableName("schedule_job")
public class ScheduleJob implements Serializable {

    private static final long serialVersionUID = 1L;

    @TableId(value = "id", type = IdType.AUTO)
    private Integer id;

    /**
     * 任务名称
     */
    private String jobName;

    /**
     * cron表达式
     */
    private String cronExpression;

    /**
     * 服务名称
     */
    private String beanName;

    /**
     * 方法名称
     */
    private String methodName;

    /**
     * 状态 1.启动 2.暂停
     */
    private int status;

    /**
     * 是否删除 0.否 1.是
     */
    @TableField(fill = FieldFill.INSERT)
    @TableLogic
    private Boolean deleteFlag;

    /**
     * 创建人id
     */
    @TableField(fill = FieldFill.INSERT)
    private Integer creatorId;

    /**
     * 创建人
     */
    @TableField(fill = FieldFill.INSERT)
    private String creatorName;

    /**
     * 创建时间
     */
    @TableField(fill = FieldFill.INSERT)
    private LocalDateTime createdTime;

    /**
     * 更新时间
     */
    @TableField(fill = FieldFill.UPDATE)
    private LocalDateTime updatedTime;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getJobName() {
        return jobName;
    }

    public void setJobName(String jobName) {
        this.jobName = jobName;
    }

    public String getCronExpression() {
        return cronExpression;
    }

    public void setCronExpression(String cronExpression) {
        this.cronExpression = cronExpression;
    }

    public String getBeanName() {
        return beanName;
    }

    public void setBeanName(String beanName) {
        this.beanName = beanName;
    }

    public String getMethodName() {
        return methodName;
    }

    public void setMethodName(String methodName) {
        this.methodName = methodName;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public Boolean getDeleteFlag() {
        return deleteFlag;
    }

    public void setDeleteFlag(Boolean deleteFlag) {
        this.deleteFlag = deleteFlag;
    }

    public Integer getCreatorId() {
        return creatorId;
    }

    public void setCreatorId(Integer creatorId) {
        this.creatorId = creatorId;
    }

    public String getCreatorName() {
        return creatorName;
    }

    public void setCreatorName(String creatorName) {
        this.creatorName = creatorName;
    }

    public LocalDateTime getCreatedTime() {
        return createdTime;
    }

    public void setCreatedTime(LocalDateTime createdTime) {
        this.createdTime = createdTime;
    }

    public LocalDateTime getUpdatedTime() {

    }

    public void setUpdatedTime(LocalDateTime updatedTime) {
        this.updatedTime = updatedTime;
    }
}

public enum JobOperateEnum {
    START(1, "启动"),
    PAUSE(2, "暂停"),
    DELETE(3, "删除");

    private final Integer value;
    private final String desc;

    JobOperateEnum(final Integer value, final String desc) {
        this.value = value;
        this.desc = desc;
    }

    public Serializable getValue() {
        return this.value;
    }

    // Jackson 注解为 JsonValue 返回中文 json 描述
    public String getDesc() {
        return this.desc;
    }

    public String getEnumName() {
        return name();
    }
}
7.任务的调度工厂（主要是实现具体的执行）QuartzFactory.class
public class QuartzFactory implements Job {

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {

        //获取调度数据
        ScheduleJob scheduleJob = (ScheduleJob) jobExecutionContext.getMergedJobDataMap().get("scheduleJob");

        //获取对应的Bean
        Object object = SpringUtil.getBean(scheduleJob.getBeanName());
        try {
            //利用反射执行对应方法
            Method method = object.getClass().getMethod(scheduleJob.getMethodName());
            method.invoke(object);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
8.具体的任务调度以及触发设置：QuartzServiceImpl.class（略过接口）
@Service
@Transactional
public class QuartzServiceImpl implements QuartzService {

    /**
     * 调度器
     */
    @Autowired
    private Scheduler scheduler;

    @Autowired
    private ScheduleJobService jobService;

    @Override
    public void timingTask() {

        //查询数据库是否存在需要定时的任务
        List<ScheduleJob> scheduleJobs = jobService.list();
        if (scheduleJobs != null) {
            scheduleJobs.forEach(this::addJob);
        }
    }

    @Override
    public void addJob(ScheduleJob job) {
        try {
            //创建触发器
            Trigger trigger = TriggerBuilder.newTrigger().withIdentity(job.getJobName())
                    .withSchedule(CronScheduleBuilder.cronSchedule(job.getCronExpression()))
                    .startNow()
                    .build();

            //创建任务
            JobDetail jobDetail = JobBuilder.newJob(QuartzFactory.class)
                    .withIdentity(job.getJobName())
                    .build();

            //传入调度的数据，在QuartzFactory中需要使用
            jobDetail.getJobDataMap().put("scheduleJob", job);

            //调度作业
            scheduler.scheduleJob(jobDetail, trigger);

        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    public void operateJob(JobOperateEnum jobOperateEnum, ScheduleJob job) throws SchedulerException {
        JobKey jobKey = new JobKey(job.getJobName());
        JobDetail jobDetail = scheduler.getJobDetail(jobKey);
        if (jobDetail == null) {
            //抛异常
        }
        switch (jobOperateEnum) {
            case START:
                scheduler.resumeJob(jobKey);
                break;
            case PAUSE:
                scheduler.pauseJob(jobKey);
                break;
            case DELETE:
                scheduler.deleteJob(jobKey);
                break;
        }
    }

    @Override
    public void startAllJob() throws SchedulerException {
        scheduler.start();
    }

    @Override
    public void pauseAllJob() throws SchedulerException {
        scheduler.standby();
    }
}
9.实现CommandLineRunner接口，以达到开机启动执行：JobSchedule.class
@Component
public class JobSchedule implements CommandLineRunner {

    @Autowired
    private QuartzService taskService;

    /**
     * 任务调度开始
     * @param strings
     * @throws Exception
     */
    @Override
    public void run(String... strings) throws Exception {
        System.out.println("任务调度开始==============任务调度开始");
        taskService.timingTask();
        System.out.println("任务调度结束==============任务调度结束");
    }
}

10.基础的配置完成，以下是几个简单的例子

执行的Job1：

@Component("testJob01")
@Transactional
public class TestJob01 {

    public void execute() {
        System.out.println("-------------------TestJob01任务执行开始-------------------");
        System.out.println(new Date());
        System.out.println("-------------------TestJob01任务执行结束-------------------");
    }
}

执行的Job2：

@Component("testJob02")
@Transactional
public class TestJob02 {

    public void execute() {
        System.out.println("-------------------TestJob02任务执行开始-------------------");
        System.out.println(new Date());
        System.out.println("-------------------TestJob02任务执行结束-------------------");
    }
}

配置的数据库：

11.业务类实现：ScheduleJobServiceImpl.class（略过接口）

@Service
@Transactional
public class ScheduleJobServiceImpl extends ServiceImpl<ScheduleJobMapper, ScheduleJob> implements ScheduleJobService {

    @Autowired
    private QuartzService quartzService;

    @Override
    public void add(ScheduleJob job) {

        //此处省去数据验证
        this.save(job);

        //加入job
        try {
            quartzService.addJob(job);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public void start(int id) {
        //此处省去数据验证
        ScheduleJob job = this.getById(id);
        job.setStatus(1);
        this.updateById(job);

        //执行job
        try {
            quartzService.operateJob(JobOperateEnum.START, job);
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void pause(int id) {
        //此处省去数据验证
        ScheduleJob job = this.getById(id);
        job.setStatus(2);
        this.updateById(job);

        //执行job
        try {
            quartzService.operateJob(JobOperateEnum.PAUSE, job);
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void delete(int id) {
        //此处省去数据验证
        ScheduleJob job = this.getById(id);
        this.removeById(id);

        //执行job
        try {
            quartzService.operateJob(JobOperateEnum.DELETE, job);
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void startAllJob() {
        //此处省去数据验证
        ScheduleJob job = new ScheduleJob();
        job.setStatus(1);
        this.update(job, new QueryWrapper<>());

        //执行job
        try {
            quartzService.startAllJob();
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void pauseAllJob() {
        //此处省去数据验证
        ScheduleJob job = new ScheduleJob();
        job.setStatus(2);
        this.update(job, new QueryWrapper<>());

        //执行job
        try {
            quartzService.pauseAllJob();
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }
}

12.Controller类：ScheduleJobController.class

@RestController
@RequestMapping("/job")
public class ScheduleJobController {

    @Autowired
    private ScheduleJobService jobService;

    @GetMapping(value = "/hello")
    public String helloSpringBoot() {
        return "Hello quartz!";
    }

    @GetMapping("/add")
    public String add() {
        ScheduleJob job = new ScheduleJob();
        job.setJobName("任务02");
        job.setCronExpression("0/2 * * * * ?");
        job.setBeanName("testJob02");
        job.setMethodName("execute");
        jobService.add(job);
        return "新增定时任务成功";
    }

    @GetMapping("/start/{id}")
    public String start(@PathVariable("id") Integer id) {
        jobService.start(id);
        return "启动定时任务成功";
    }

    @GetMapping("/pause/{id}")
    public String pause(@PathVariable("id") Integer id) {
        jobService.pause(id);
        return "暂停定时任务成功";
    }

    @GetMapping("/delete/{id}")
    public String delete(@PathVariable("id") Integer id) {
        jobService.delete(id);
        return "删除定时任务成功";
    }

    @GetMapping("/startAllJob")
    public String startAllJob() {
        jobService.startAllJob();
        return "启动所有定时任务成功";
    }

    @GetMapping("/pauseAllJob")
    public String pauseAllJob() {
        jobService.pauseAllJob();
        return "暂停所有定时任务成功";
    }
}

使用spring自带的@Scheduled注解实现的定时任务

@Component
@EnableScheduling
public class SchedulerTask {

    private int count = 0;

    @Scheduled(cron = "*/1 * * * * ?")
    private void process() {
        System.out.println("this is scheduler task runing  " + (count++));
        System.out.println("当前时间：" + LocalTime.now());
    }
}
