springbootz整合quartz

2019-09-19 14:00:24 作者：互联网

近期公司项目任务，需要在项目中添加定时任务，整理了一天，在项目中已经可用

quartz概述

Quartz是一个完全由Java编写的开源任务调度的框架，通过触发器设置作业定时运行规则，控制作业的运行时间。其中quartz集群通过故障切换和负载平衡的功能，能给调度器带来高可用性和伸缩性。主要用来执行定时任务

quartz核心元素

Quartz核心要素有Scheduler、Trigger、Job、JobDetail，其中trigger和job、jobDetail为元数据，而Scheduler为实际进行调度的控制器。

以上都是摘抄于百度，现在来写一下步骤

整合quartz

前期准备工作
pom.xml

任务实体类，这个类是自己定义的实体类，可以根据自己的项目需求来定

public class Job implements Serializable {

    /**
	 * 
	 */
	private static final long serialVersionUID = -8753803549325852334L;

	private Integer jobId;

	private String jobName;
	
    private String params; //参数
    
    private Date runTime;
    
    private String cronExpression; //cron表达式

    private Byte status; //任务状态 0，运行 1，暂停

    private String remark; //备注

配置类

@Configuration
public class QuartzConfig {
   
   @Autowired
   DataSource dataSource;
   
   @Bean
   public SchedulerFactoryBean scheduler() {

       //quartz参数
       Properties prop = new Properties();
       //配置实例
       prop.put("org.quartz.scheduler.instanceId", "AUTO");
       //线程池配置
       prop.put("org.quartz.threadPool.threadCount", "5");
       //JobStore配置
       prop.put("org.quartz.jobStore.class", "org.quartz.impl.jdbcjobstore.JobStoreTX");
       prop.put("org.quartz.jobStore.tablePrefix", "QRTZ_");

       SchedulerFactoryBean factory = new SchedulerFactoryBean();
       factory.setDataSource(dataSource);
       factory.setQuartzProperties(prop);
       factory.setSchedulerName("MyScheduler");//数据库中存储的名字
       //QuartzScheduler 延时启动，应用启动5秒后 QuartzScheduler 再启动
       factory.setStartupDelay(5);

       //factory.setApplicationContextSchedulerContextKey("applicationContextKey");
       //可选，QuartzScheduler 启动时更新己存在的Job，这样就不用每次修改targetObject后删除qrtz_job_details表对应记录了
       factory.setOverwriteExistingJobs(true);
       //设置自动启动，默认为true
       factory.setAutoStartup(true);

       return factory;
   }
}

定时器方法（类似于工具类，启动，暂停都在此类中）

public class SchedulerUtils {

   /**
    * 创建任务
    */
   public static void createJob(Scheduler scheduler, Job scheduleJob) {

       try {
           Integer jobId = scheduleJob.getJobId();
           //创建Job对象
           JobDetail job = JobBuilder.newJob(QuartzJob.class).withIdentity("JOB_" + jobId).build();
           //获取cron表达式 并创建对象
           CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(scheduleJob.getCronExpression())
                   .withMisfireHandlingInstructionDoNothing();
           //创建触发器
           CronTrigger trigger = TriggerBuilder.newTrigger()
                   .withIdentity("TRIGGET_" + jobId)
                   .withSchedule(cronScheduleBuilder) //将cron表达式配置到触发器
                   .build();

           //将对象josn序列化存储到Job的getJobDataMap()方法中，为后续根据获取属性执行对应的类的任务
           job.getJobDataMap().put("JOB_PARAM_KEY", JSON.toJSONString(scheduleJob));
           //存数据
           scheduler.scheduleJob(job, trigger);
          // scheduler.pauseJob(JobKey.jobKey("JOB_" + jobId));//使任务处于等待状态,创建后不会执行
       } catch (SchedulerException e) {
       	e.printStackTrace();
           throw new MyException("创建任务失败", e);
       }
   }

   /**
    * 更新任务
    */
   public static void updateJob(Scheduler scheduler, Job scheduleJob) {
       //获取新的cron表达式
       CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(scheduleJob.getCronExpression())
               .withMisfireHandlingInstructionDoNothing();

       Integer jobId = scheduleJob.getJobId();

       try {
           //拿到原有的trigger
           TriggerKey triggerKey = TriggerKey.triggerKey("TRIGGER_" + jobId);
           CronTrigger trigger = (CronTrigger) scheduler.getTrigger(triggerKey);
           //为原有的trigger赋予新的cron表达式
           trigger = trigger.getTriggerBuilder().withIdentity(triggerKey)
                   .withSchedule(cronScheduleBuilder).build();
           //执行原有的trigger更新
           scheduler.rescheduleJob(triggerKey, trigger);
       } catch (SchedulerException e) {
           e.printStackTrace();
           throw new MyException("更新定时任务失败", e);
       }
   }

   /**
    * 删除任务
    */
   public static void deleteJob(Scheduler scheduler, Long jobId) {
       try {
           scheduler.deleteJob(JobKey.jobKey("JOB_" + jobId));
       } catch (SchedulerException e) {
           e.printStackTrace();
           throw new MyException("删除定时任务失败", e);
       }
   }

   /**
    * 恢复任务
    */
   public static void resumeJob(Scheduler scheduler, Long jobId) {
       try {
           scheduler.resumeJob(JobKey.jobKey("JOB_" + jobId));
       } catch (SchedulerException e) {
           e.printStackTrace();
           throw new MyException("恢复定时任务失败", e);
       }
   }

   /**
    * 立即执行定时任务
    */
   public static void run(Scheduler scheduler, Long jobId) {
       try {
           //只执行一次并且不会改变任务的状态
           scheduler.triggerJob(JobKey.jobKey("JOB_" + jobId));
       } catch (SchedulerException e) {
           e.printStackTrace();
           throw new MyException("立即执行定时任务失败", e);
       }
   }

   /**
    * 暂停任务
    *
    * @param scheduler
    * @param jobId
    */
   public static void pauseJob(Scheduler scheduler, Long jobId) {
       try {
           scheduler.pauseJob(JobKey.jobKey("JOB_" + jobId));
       } catch (SchedulerException e) {
           e.printStackTrace();
           throw new MyException("暂停定时任务失败", e);
       }
   }
}

任务执行（这个类中写你的真的任务，也就是逻辑代码）

public class QuartzJob extends QuartzJobBean {
   private Logger logger = LoggerFactory.getLogger(getClass());

   @Override
   protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
       System.err.println("执行quartz任务。。。。。");

       logger.info("任务已经执行了");

   }

}

以上配置完之后，应该就可以在项目中运行使用了！

可能会遇到的异常

我的mysql之前是5.1.6，启动会出现异常，换成5.1.26正常
