Quartz之JobBuilder

JobBuilder也可向任务传递数据,通常情况下,我们使用它就可向任务类发送数据了，如有特别复杂的传递参数,它提供了一个传递:JobDataMap对象的方法,当然这个要根据个人使用习惯来说了呀  它重载了方法usingJobData(),如下图:

JobDetail job = newJob(StatefulDumbJob.class)
            .withIdentity("statefulJob1", "group1")
            .usingJobData(StatefulDumbJob.EXECUTION_DELAY, 10000L)//传递数据
            .build();
    
        SimpleTrigger trigger = newTrigger() 
            .withIdentity("trigger1", "group1")
            .startAt(startTime)
            .withSchedule(simpleSchedule()
                    .withIntervalInSeconds(3)
                    .repeatForever())
            .build();
        
        Date ft = sched.scheduleJob(job, trigger);
        log.error("任务key: "+job.getKey() + ",执行运行时间: " + sdf.format(ft) +  
                ",触发器重复执行次数: " + trigger.getRepeatCount() + 
                ",触发器执行时间: " + trigger.getRepeatInterval() / 1000 + " seconds");

在任务类一样可取出：

JobDataMap map = context.getJobDetail().getJobDataMap();
        int executeCount = 0;
        if (map.containsKey(NUM_EXECUTIONS)) {
            executeCount = map.getInt(NUM_EXECUTIONS);
        }
        executeCount++;
        map.put(NUM_EXECUTIONS, executeCount);
