二、quartz的主要方法

必须注入Scheduler ------ @Autowired private Scheduler scheduler

ScheduleJob实体对象：实现Job------具体的任务内容对象

1、添加任务：

public void addJob(ScheduleJob job) {

try {
// 创建jobDetail实例，绑定Job实现类
// 指明job的名称，所在组的名称，以及绑定job类

Class<? extends Job> jobClass = (Class<? extends Job>) (Class.forName(job.getBeanClass()).newInstance()
.getClass());

// 任务名称和组构成任务key
           JobDetail jobDetail = JobBuilder.newJob(jobClass).withIdentity(job.getJobName(), job.getJobGroup()).build();
           // 定义调度触发规则
           // 使用cornTrigger规则 // 触发器key
           Trigger trigger = TriggerBuilder.newTrigger().withIdentity(job.getJobName(), job.getJobGroup())
                   .startAt(DateBuilder.futureDate(1, IntervalUnit.SECOND))
                   .withSchedule(CronScheduleBuilder.cronSchedule(job.getCronExpression())).startNow().build();
           // 把作业和触发器注册到任务调度中
           scheduler.scheduleJob(jobDetail, trigger);
           // 启动
           if (!scheduler.isShutdown()) {
               scheduler.start();
           }
       } catch (Exception e) {
           e.printStackTrace();
       }

}

2、获取所有计划中的任务列表：

public List<ScheduleJob> getAllJob() throws SchedulerException {
       GroupMatcher<JobKey> matcher = GroupMatcher.anyJobGroup();
       Set<JobKey> jobKeys = scheduler.getJobKeys(matcher);
       List<ScheduleJob> jobList = new ArrayList<ScheduleJob>();
       for (JobKey jobKey : jobKeys) {
           List<? extends Trigger> triggers = scheduler.getTriggersOfJob(jobKey);
           for (Trigger trigger : triggers) {
               ScheduleJob job = new ScheduleJob();
               job.setJobName(jobKey.getName());
               job.setJobGroup(jobKey.getGroup());
               job.setDescription("触发器:" + trigger.getKey());
               Trigger.TriggerState triggerState = scheduler.getTriggerState(trigger.getKey());
               job.setJobStatus(triggerState.name());
               if (trigger instanceof CronTrigger) {
                   CronTrigger cronTrigger = (CronTrigger) trigger;
                   String cronExpression = cronTrigger.getCronExpression();
                   job.setCronExpression(cronExpression);
               }
               jobList.add(job);
           }
       }
       return jobList;
   }

3、获取所有计划中正在运行的任务列表

public List<ScheduleJob> getRunningJob() throws SchedulerException {
       List<JobExecutionContext> executingJobs = scheduler.getCurrentlyExecutingJobs();
       List<ScheduleJob> jobList = new ArrayList<ScheduleJob>(executingJobs.size());
       for (JobExecutionContext executingJob : executingJobs) {
           ScheduleJob job = new ScheduleJob();
           JobDetail jobDetail = executingJob.getJobDetail();
           JobKey jobKey = jobDetail.getKey();
           Trigger trigger = executingJob.getTrigger();
           job.setJobName(jobKey.getName());
           job.setJobGroup(jobKey.getGroup());
           job.setDescription("触发器:" + trigger.getKey());
           Trigger.TriggerState triggerState = scheduler.getTriggerState(trigger.getKey());
           job.setJobStatus(triggerState.name());
           if (trigger instanceof CronTrigger) {
               CronTrigger cronTrigger = (CronTrigger) trigger;
               String cronExpression = cronTrigger.getCronExpression();
               job.setCronExpression(cronExpression);
           }
           jobList.add(job);
       }
       return jobList;
   }

4、暂停任务：

public void pauseJob(ScheduleJob scheduleJob) throws SchedulerException {
       JobKey jobKey = JobKey.jobKey(scheduleJob.getJobName(), scheduleJob.getJobGroup());
       scheduler.pauseJob(jobKey);
   }

5、恢复任务：

public void resumeJob(ScheduleJob scheduleJob) throws SchedulerException {

// 任务key：任务名+组
       JobKey jobKey = JobKey.jobKey(scheduleJob.getJobName(), scheduleJob.getJobGroup());
       scheduler.resumeJob(jobKey);
   }

6、删除任务：

public void deleteJob(ScheduleJob scheduleJob) throws SchedulerException {

   // 任务key：任务名+组
       JobKey jobKey = JobKey.jobKey(scheduleJob.getJobName(), scheduleJob.getJobGroup());
       scheduler.deleteJob(jobKey);

}

7、立即执行任务，只会运行一次：

public void runOnce(ScheduleJob scheduleJob) throws SchedulerException {

// 任务key：任务名+组
       JobKey jobKey = JobKey.jobKey(scheduleJob.getJobName(), scheduleJob.getJobGroup());
       scheduler.triggerJob(jobKey);
   }

8、更新任务的时间表达式：

public void updateJobCron(ScheduleJob scheduleJob) throws SchedulerException {
       TriggerKey triggerKey = TriggerKey.triggerKey(scheduleJob.getJobName(), scheduleJob.getJobGroup());
       CronTrigger trigger = (CronTrigger) scheduler.getTrigger(triggerKey);
       CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(scheduleJob.getCronExpression());
       trigger = trigger.getTriggerBuilder().withIdentity(triggerKey).withSchedule(scheduleBuilder).build();
       scheduler.rescheduleJob(triggerKey, trigger);
   }
