      前言

      在日常的工作中,定时任务也是一个非常常见的需求,可以使用注解实现,但是使用这种方式有几个问题,首先就是如果修改比较麻烦,而且没有提供特定的页面对定时任务进行可视化管理。所以quartz就应运而生。本文将介绍如何实现springboot与quartz的整合。

      1.目录结构

      配置类 配置SchedulerFactory固化定时任务和日志的业务类定时任务类运行配置

      2.原理

      1. scheduler是一个计划调度器容器(总部),容器里面可以盛放众多的JobDetail和trigger,当容器启动后,里面的每个JobDetail都会根据trigger按部就班自动去执行。
      2. JobDetail是一个可执行的工作,它本身可能是有状态的。
      3. Trigger代表一个调度参数的配置,什么时候去调。
      4. 当JobDetail和Trigger在scheduler容器上注册后,形成了装配好的作业(JobDetail和Trigger所组成的一对儿),就可以伴随容器启动而调度执行了。
      5. scheduler是个容器,容器中有一个线程池,用来并行调度执行每个作业,这样可以提高容器效率

      3.表结构

      自带有11张系统表和2张业务表(自建),其中绿色为自己建立的表

      4.整合springboot

      1.pom文件

              <dependency>
                  <groupId>org.quartz-scheduler</groupId>
                  <artifactId>quartz</artifactId>
                  <version>2.2.1</version>
              </dependency>

      2.ScheduleConfig

      配置工厂类的参数。

      @Configuration
      public class ScheduleConfig {
       
      	@Bean
      	public SchedulerFactoryBean schedulerFactoryBean(DataSource dataSource) {
      		SchedulerFactoryBean factory = new SchedulerFactoryBean();
      		factory.setDataSource(dataSource);
      		// quartz参数
      		Properties prop = new Properties();
      		prop.put("org.quartz.scheduler.instanceName", "QUARTZ");
      		prop.put("org.quartz.scheduler.instanceId", "AUTO");
      		// 线程池配置
      		prop.put("org.quartz.threadPool.class", "org.quartz.simpl.SimpleThreadPool");
      		prop.put("org.quartz.threadPool.threadCount", "20");
      		prop.put("org.quartz.threadPool.threadPriority", "5");
      		// JobStore配置
      		prop.put("org.quartz.jobStore.class", "org.quartz.impl.jdbcjobstore.JobStoreTX");
      		// 集群配置
      		prop.put("org.quartz.jobStore.isClustered", "true");
      		prop.put("org.quartz.jobStore.clusterCheckinInterval", "15000");
      		prop.put("org.quartz.jobStore.maxMisfiresToHandleAtATime", "1");
      		prop.put("org.quartz.jobStore.txIsolationLevelSerializable", "true");
      		// sqlserver 启用
      		prop.put("org.quartz.jobStore.misfireThreshold", "12000");
      		prop.put("org.quartz.jobStore.tablePrefix", "QRTZ_");
      		factory.setQuartzProperties(prop);
      		factory.setSchedulerName("QUARTZ");
      		// 延时启动
      		factory.setStartupDelay(1);
      		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;
      	}
      }

      3.业务类

      主要是为页面提供接口。

      @RestController
      @RequestMapping("/qrtzJob")
      public class QrtzJobController {
       
          @Autowired
          private QrtzJobService qrtzJobService;
       
          /**
           * 检查表达式
           * 
           * @param cron
           * @return
           */
          @GetMapping("/check")
          public boolean checkCron(String cron) {
              try {
                  return CronExpression.isValidExpression(cron);
              } catch (Exception e) {
                  return false;
              }
          }
       
          /**
           * 通过对象查询数据
           *
           * @param qrtzJobVO 请求对象
           * @return 数据集合
           */
          @GetMapping("/selectQrtzJob")
          @ApiOperation(value = "通过实体查询", notes = "通过实体查询")
          public Result<List<QrtzJobVO>>
              selectQrtzJob(@ApiParam(name = "入参对象", value = "实体", required = false) QrtzJobVO qrtzJobVO) {
              Result<List<QrtzJobVO>> resultVO = new Result<>();
              // 业务查询
              List<QrtzJobVO> resultListQrtzJob = qrtzJobService.queryQrtzJobAll(qrtzJobVO);
              resultVO.setData(resultListQrtzJob);
              return resultVO;
          }
       
          /**
           * 通过对象增加数据
           *

           */
          @PostMapping("/createQrtzJob")
          @ApiOperation(value = "通过实体添加", notes = "通过实体添加")
          public Result
              createQrtzJob(@ApiParam(name = "入参对象", value = "实体", required = false) @RequestBody QrtzJobVO qrtzJobVO) {
              Result resultVO = new Result();
              // 业务处理
              qrtzJobService.createScheduleJob(qrtzJobVO);
              return resultVO;
          }
       
          /**
           * 通过对象修改

          @PutMapping("/updateQrtzJob")
          @ApiOperation(value = "通过实体修改", notes = "通过实体修改")
          public Result
              updateQrtzJob(@ApiParam(name = "入参对象", value = "实体", required = false) @RequestBody QrtzJobVO qrtzJobVO) {
              Result resultVO = new Result();
              // 业务处理
              qrtzJobService.updateScheduleJob(qrtzJobVO);
              return resultVO;
          }
       
          /**
           * 通过对象删除
           *

           */
          @DeleteMapping("/deleteQrtzJob")
          @ApiOperation(value = "通过实体删除", notes = "通过实体删除")
          public Result
              deleteQrtzJob(@ApiParam(name = "入参对象", value = "实体", required = false) @RequestBody QrtzJobVO qrtzJobVO) {
              Result resultVO = new Result();
              // 业务处理
              qrtzJobService.deleteScheduleJob(qrtzJobVO);
              return resultVO;
          }
       
          /**
           * 运行定时任务

           */
          @GetMapping("/runJob")
          public Result
              runJob(@ApiParam(name = "入参对象", value = "实体", required = false) @RequestBody List<QrtzJobVO> qrtzJobVO) {
              Result resultVO = new Result();
              // 业务处理
              qrtzJobService.run(qrtzJobVO);
              return resultVO;
          }
       
          /**
           * 暂停定时任务
           * 
           * @param qrtzJobVO
           * @return
           */
          @GetMapping("/pauseJob")
          public Result
              pauseJob(@ApiParam(name = "入参对象", value = "实体", required = false) @RequestBody List<QrtzJobVO> qrtzJobVO) {
              Result resultVO = new Result();
              // 业务处理
              qrtzJobService.pause(qrtzJobVO);
              return resultVO;
          }
       
          @GetMapping("resumeJob")
          public Result
              resumeJob(@ApiParam(name = "入参对象", value = "实体", required = false) @RequestBody List<QrtzJobVO> qrtzJobVO) {

              return resultVO;
          }
       
      }

      4.运行配置

      ScheduleUtils:将新添加的trigger,jobDetail放入scheduler中。

      public class ScheduleUtils {
       
          private static final Logger log = LoggerFactory.getLogger(ScheduleUtils.class);
       
          private static final String JOB_NAME_PREFIX = "TASK_";
       
          private static TriggerKey getTriggerKey(Long jobId) {
              return TriggerKey.triggerKey("TASK_" + jobId);
          }
       
          private static JobKey getJobKey(Long jobId) {
              return JobKey.jobKey("TASK_" + jobId);
          }
       
          public static CronTrigger getCronTrigger(Scheduler scheduler, Long jobId) {
              try {
                  return (CronTrigger)scheduler.getTrigger(getTriggerKey(jobId));
              } catch (SchedulerException e) {
                  log.error("获取Cron表达式失败", e);
                  return null;
              }
          }
       
          public static void createScheduleJob(Scheduler scheduler, QrtzJobVO scheduleJob) {
              try {
                  JobDetail jobDetail = JobBuilder.newJob(com.job.util.ScheduleJob.class)
                      .withIdentity(getJobKey(scheduleJob.getJobId())).build();
                  CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(scheduleJob.getCronExpression())
                      .withMisfireHandlingInstructionDoNothing();
                  CronTrigger trigger = (CronTrigger)TriggerBuilder.newTrigger()
                      .withIdentity(getTriggerKey(scheduleJob.getJobId())).withSchedule(scheduleBuilder).build();
                  jobDetail.getJobDataMap().put("JOB_PARAM_KEY", scheduleJob);
                  scheduler.scheduleJob(jobDetail, trigger);
                  if (scheduleJob.getStatus().equals(CommonConstant.QUARTZ_PAUSE)) {
                      pauseJob(scheduler, scheduleJob.getJobId());
                  }
              } catch (SchedulerException e) {
                  log.error("创建定时任务失败", e);
              }
          }
       
          public static void updateScheduleJob(Scheduler scheduler, QrtzJobVO scheduleJob) {
              try {
                  TriggerKey triggerKey = getTriggerKey(scheduleJob.getJobId());
                  CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(scheduleJob.getCronExpression())
                      .withMisfireHandlingInstructionDoNothing();
                  CronTrigger trigger = getCronTrigger(scheduler, scheduleJob.getJobId());
                  if (trigger == null) {
                      throw new SchedulerException("获取Cron表达式失败");
                  }
                  trigger =
                      (CronTrigger)trigger.getTriggerBuilder().withIdentity(triggerKey).withSchedule(scheduleBuilder).build();
                  trigger.getJobDataMap().put("JOB_PARAM_KEY", scheduleJob);
                  scheduler.rescheduleJob(triggerKey, trigger);
                  if (scheduleJob.getStatus().equals(CommonConstant.QUARTZ_PAUSE)) {
                      pauseJob(scheduler, scheduleJob.getJobId());
                  }
              } catch (SchedulerException e) {
                  log.error("更新定时任务失败", e);
              }
          }
       
          public static void run(Scheduler scheduler, QrtzJobVO scheduleJob) {
              try {
                  JobDataMap dataMap = new JobDataMap();
                  dataMap.put("JOB_PARAM_KEY", scheduleJob);
                  scheduler.triggerJob(getJobKey(scheduleJob.getJobId()), dataMap);
              } catch (SchedulerException e) {
                  log.error("执行定时任务失败", e);
              }
          }
       
          public static void pauseJob(Scheduler scheduler, Long jobId) {
              try {
                  scheduler.pauseJob(getJobKey(jobId));
              } catch (SchedulerException e) {
                  log.error("暂停定时任务失败", e);
              }
          }
       
          public static void resumeJob(Scheduler scheduler, Long jobId) {
              try {
                  scheduler.resumeJob(getJobKey(jobId));
              } catch (SchedulerException e) {
                  log.error("恢复定时任务失败", e);
              }
          }
       
          public static void deleteScheduleJob(Scheduler scheduler, Long jobId) {
              try {
                  scheduler.deleteJob(getJobKey(jobId));
              } catch (SchedulerException e) {
                  log.error("删除定时任务失败", e);
              }
          }
      }

      5.ScheduleJob 

      用于执行定时任务。

      public class ScheduleJob extends QuartzJobBean {
       
          private static final Logger log = LoggerFactory.getLogger(ScheduleJob.class);
       
          private ExecutorService service = Executors.newSingleThreadExecutor();
       
          @Override
          protected void executeInternal(JobExecutionContext context) {
              QrtzJobVO scheduleJob = (QrtzJobVO)context.getMergedJobDataMap().get("JOB_PARAM_KEY");
              QrtzJobLogService scheduleJobLogService = (QrtzJobLogService) SpringContextUtil.getBean(QrtzJobLogService.class);
              QrtzJobLogVO jobLog = new QrtzJobLogVO();
              jobLog.setJobId(scheduleJob.getJobId());
              jobLog.setBeanName(scheduleJob.getBeanName());
              jobLog.setMethodName(scheduleJob.getMethodName());
              if (CommonUtil.isEmpty(scheduleJob.getParams())) {
                  jobLog.setParams("");
              } else {
                  jobLog.setParams(scheduleJob.getParams());
              }
              long startTime = System.currentTimeMillis();
              try {
                  log.info("任务准备执行,任务ID:{}", scheduleJob.getJobId());
                  ScheduleRunnable task =
                      new ScheduleRunnable(scheduleJob.getBeanName(), scheduleJob.getMethodName(), scheduleJob.getParams());
                  Future<?> future = this.service.submit(task);
                  future.get();
                  long times = System.currentTimeMillis() - startTime;
                  jobLog.setTimes(Long.valueOf(times));
                  jobLog.setStatus("0");
                  log.info("任务执行完毕,任务ID:{} 总共耗时:{} 毫秒", scheduleJob.getJobId(), Long.valueOf(times));
              } catch (Exception e) {
                  log.error("任务执行失败,任务ID:" + scheduleJob.getJobId(), e);
                  long times = System.currentTimeMillis() - startTime;
                  jobLog.setTimes(Long.valueOf(times));
                  jobLog.setStatus("1");
                  jobLog.setError(StringUtils.substring(e.toString(), 0, 2000));
              } finally {
                  scheduleJobLogService.insertQrtzJobLog(jobLog);
              }
          }
      }

      6.ScheduleRunnable

      通过反射回去需要调用的类与方法。

      public class ScheduleRunnable implements Runnable {
       
          private static final Logger log = LoggerFactory.getLogger(ScheduleRunnable.class);
       
          private Object target;
       
          private Method method;
       
          private String params;
       
          ScheduleRunnable(String beanName, String methodName, String params)
              throws NoSuchMethodException, SecurityException {
              this.target = SpringContextUtil.getBean(beanName);
              this.params = params;
              if (StringUtils.isNotBlank(params)) {
                  this.method = this.target.getClass().getDeclaredMethod(methodName, new Class[] {String.class});
              } else {
                  this.method = this.target.getClass().getDeclaredMethod(methodName, new Class[0]);
              }
          }
       
          @Override
          public void run() {
              try {
                  ReflectionUtils.makeAccessible(this.method);
                  if (StringUtils.isNotBlank(this.params)) {
                      this.method.invoke(this.target, new Object[] {this.params});
                  } else {
                      this.method.invoke(this.target, new Object[0]);
                  }
              } catch (Exception e) {
                  log.error("执行定时任务失败", e);
              }
          }
      }

      5.使用

      调用以上接口 ,参数如下。

          "beanName":"任务类",
          "methodName":"任务方法",
          "params":"参数",
          "cronExpression":"表达式",
