怎样动态的配置job和cronExpression？应用quartz实现定时任务

Posted 2023-04-09

参考技术A public void task() throws SchedulerException // Initiate a Schedule Factory SchedulerFactory schedulerFactory = new StdSchedulerFactory(); // Retrieve a scheduler from schedule factory Scheduler scheduler = schedulerFactory.getScheduler(); // current time long ctime = System.currentTimeMillis(); // Initiate JobDetail with job name, job group, and executable job class JobDetail jobDetail = new JobDetail("jobDetail2", "jobDetailGroup2", SimpleQuartzJob.class); // Initiate CronTrigger with its name and group name CronTrigger cronTrigger = new CronTrigger("cronTrigger", "triggerGroup2"); try // setup CronExpression CronExpression cexp = new CronExpression("取全局变量的表达式值"); // Assign the CronExpression to CronTrigger cronTrigger.setCronExpression(cexp); catch (Exception e) e.printStackTrace(); // schedule a job with JobDetail and Trigger scheduler.scheduleJob(jobDetail, cronTrigger); // start the scheduler scheduler.start(); 本回答被提问者采纳

java quartz中CronExpression表达式，场景：每隔2周的周一到周五执行的写法。急。。。。。。。。。。。。

参考技术A :40 执行某个JOB
trigger.setEndTime(endTime) 根据日期的不同动态生成endTime 就可以做到了
单纯用一个表达式很难办到 参考技术B 每隔2周的周一到周五 早上9点执行
