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

Answer 1

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(); }
