本文实例为大家分享了springBoot+Quartz实现动态定时任务的具体代码,供大家参考,具体内容如下
目前常用的几种任务调度
- Timer,简单无门槛,一般也没人用。
- spring @Scheduled注解,一般集成于项目中,小任务很方便。
- 开源工具 Quartz,分布式集群开源工具,以下两个分布式任务应该都是基于Quartz实现的,可以说是中小型公司必选,当然也视自身需求而定。
- 分布式任务 XXL-JOB,是一个轻量级分布式任务调度框架,支持通过 Web 页面对任务进行 CRUD 操作,支持动态修改任务状态、暂停/恢复任务,以及终止运行中任务,支持在线配置调度任务入参和在线查看调度结果。
- 分布式任务 Elastic-Job,是一个分布式调度解决方案,由两个相互独立的子项目 Elastic-Job-Lite 和 Elastic-Job-Cloud 组成。定位为轻量级无中心化解决方案,使用 jar 包的形式提供分布式任务的协调服务。支持分布式调度协调、弹性扩容缩容、失效转移、错过执行作业重触发、并行调度、自诊。
- 分布式任务 Saturn,Saturn是唯品会在github开源的一款分布式任务调度产品。它是基于当当elastic-job来开发的,其上完善了一些功能和添加了一些新的feature。目前在github上开源大半年,470个star。Saturn的任务可以用多种语言开发比如python、Go、Shell、Java、php。其在唯品会内部已经发部署350+个节点,每天任务调度4000多万次。同时,管理和统计也是它的亮点。
SpringBoot项目的实现方法
1.config配置
import org.quartz.Scheduler; import org.quartz.ee.servlet.QuartzInitializerListener; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.config.PropertiesFactoryBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.core.io.ClassPathResource; import org.springframework.scheduling.quartz.SchedulerFactoryBean; import java.io.IOException; import java.util.Properties; /** * quartz配置 */ @Configuration public class SchedulerConfig { @Bean(name="SchedulerFactory") public SchedulerFactoryBean schedulerFactoryBean() throws IOException { SchedulerFactoryBean factory = new SchedulerFactoryBean(); factory.setAutoStartup(true); //factory.setStartupDelay(5);//延时5秒启动 return factory; } /* * quartz初始化监听器 */ @Bean public QuartzInitializerListener executorListener() { return new QuartzInitializerListener(); } /* * 通过SchedulerFactoryBean获取Scheduler的实例 */ @Bean(name="Scheduler") public Scheduler scheduler() throws IOException { return schedulerFactoryBean().getScheduler(); } }
2.实现方法
/** * 新建任务 * **/ @ApiOperation(value = "Test-add", notes = "Test-add") @ApiImplicitParams({ @ApiImplicitParam(name = "cruiseId", value = "巡航线id", required = true, paramType = "path"), @ApiImplicitParam(name = "jobName", value = "任务名称", required = true, paramType = "query"), @ApiImplicitParam(name = "jobGroup", value = "任务分组", required = true, paramType = "query"), @ApiImplicitParam(name = "executeDate", value = "当前时间[yyyy-MM-dd HH:mm:ss]", required = true, paramType = "query", dataType = "Date")}) @PutMapping("/test/add/{cruiseId}") public ResultBody test(@PathVariable("cruiseId") String cruiseId,@RequestParam("jobName") String jobName,@RequestParam("jobGroup") String jobGroup, @RequestParam(value = "executeDate")@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss") Date executeDate) { try { SimpleDateFormat dateFormat1 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); //构建job信息 JobDetail job = JobBuilder.newJob(CruisePlanJob.class).withIdentity(jobName, jobGroup) .withDescription("巡航计划").build(); JobDataMap jobDataMap = job.getJobDataMap(); jobDataMap.put("cruiseId", cruiseId); //CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("cron的表达式"); Trigger trigger = TriggerBuilder.newTrigger() .withIdentity("trigger" + jobName, jobGroup) .startAt(executeDate) .withSchedule(SimpleScheduleBuilder.simpleSchedule().withRepeatCount(0)) .build(); //SimpleScheduleBuilder.simpleSchedule().withRepeatCount(0).withIntervalInSeconds(20)//每隔多少秒执行一次; withRepeatCount 设置重复的次数 //.startNow().withSchedule(cronScheduleBuilder) //交由Scheduler安排触发 scheduler.scheduleJob(job, trigger); System.out.println("startJob:"+JobKey.jobKey(jobName)); } catch (Exception e) { e.printStackTrace(); return ResultBody.failed(); } return ResultBody.ok(); } /** * 删除任务 * **/ @ApiOperation(value = "Test-remove", notes = "Test-remove") @ApiImplicitParams({ @ApiImplicitParam(name = "jobName", value = "任务名称", required = true, paramType = "query"), @ApiImplicitParam(name = "jobGroup", value = "任务分组", required =http://www.cppcns.com true, paramType = "query")}) @GetMapping("/test/remove") public ResultBody remove(@RequestParam("jobName") String jobName,@RequestParam("jobGroup") String jobGroup) { try { TriggerKey triggerKey = TriggerKey.triggerKey(jobName, jobGroup); // 停止触发器 scheduler.pauseTrigger(triggerKey); // 移除触发器 scheduler.unscheduleJob(triggerKey); // 删除任务 恰卡编程网 boolean result = scheduler.deleteJob(JobKey.jobKey(jobName, jobGroup恰卡编程网)); System.out.println(result); System.out.println("removeJob:"+JobKey.jobKey(jobName)); } catch (Exception e) { e.printStackTrace(); return ResultBody.failed(); } return ResultBody.ok(); }
3.CruisePlanJob类实现具体逻辑
@Slf4j public class CruisePlanJob implements Job { @Override public void execute(JobExecutionContext context) { try{ JobDataMap jdMap = context.getJobDetail().getJobDataMap(); String cruiseId = (String) jdMap.get("cruinWxsWzEeaseId"); String panId = (String) jdMap.get("panId"); String userId = (String) jdMap.get("userId"); String appId = (String) jdMap.get("appId"); //TODO 逻辑待补充 log.info("cruisePlan-CruisePlanJob-计划执行开始===>panId:{}---cruiseId:{}---appId:{}---userId:{}---resultBody:{}", panId, cruiseId, appId, userId, resultBody); }catch (Exception e){ e.printStackTrace(); } } }
4.另外两种任务的方法
//恢复任务 scheduler.resumeJob(key); //停止任务 scheduler.pauseJob(key);
