此处使用的是Quartz中SimpleScheduleBuilder类，非CronScheduleBuilder，CronScheduleBuilder是Cron表达式的。具体请自行百度。

 

Java代码  

1. /** 
2.      * 新增任务 
3.      * @param scheduleJob 
4.      * @throws Exception  
5.      */  
6.     @Override  
7.     @SuppressWarnings("unchecked")  
8.     public void addJobSimple(ScheduleJob scheduleJob) throws Exception{  
9.         TriggerKey triggerKey = TriggerKey.triggerKey(scheduleJob.getJobName(), scheduleJob.getJobGroup());  
10.         //任务触发  
11.         Trigger trigger = scheduler.getTrigger(triggerKey);  
12.         if (null == trigger) {  
13.             JobDetail jobDetail = JobBuilder.newJob((Class<? extends Job>) Class.forName(scheduleJob.getClazz()))  
14.               .withIdentity(scheduleJob.getJobName(), scheduleJob.getJobGroup()).build();  
15.             jobDetail.getJobDataMap().put("scheduleJob", scheduleJob);  
16.               
17.             SimpleScheduleBuilder simpleScheduleBuilder = SimpleScheduleBuilder.simpleSchedule();  
18.             if("秒".equals(scheduleJob.getTimeType()) ||   
19.                     "second".equalsIgnoreCase(scheduleJob.getTimeType())){  
20.                 simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue()).repeatForever();  
21.             }else if("分".equals(scheduleJob.getTimeType()) || "分钟".equals(scheduleJob.getTimeType()) ||   
22.                     "minute".equalsIgnoreCase(scheduleJob.getTimeType())){  
23.                 simpleScheduleBuilder.withIntervalInMinutes(scheduleJob.getTimeValue()).repeatForever();  
24.             }else if("时".equals(scheduleJob.getTimeType()) || "小时".equals(scheduleJob.getTimeType()) ||   
25.                     "hour".equalsIgnoreCase(scheduleJob.getTimeType())){  
26.                 simpleScheduleBuilder.withIntervalInHours(scheduleJob.getTimeValue()).repeatForever();  
27.             }else if("天".equals(scheduleJob.getTimeType()) ||   
28.                     "date".equalsIgnoreCase(scheduleJob.getTimeType())){  
29.                 simpleScheduleBuilder.withIntervalInHours(scheduleJob.getTimeValue()).repeatForever();  
30.             }  
31.             ScheduleBuilder<SimpleTrigger> schedBuilder = simpleScheduleBuilder.withMisfireHandlingInstructionNextWithRemainingCount();  
32.               
33.             trigger =TriggerBuilder.newTrigger().withIdentity(scheduleJob.getJobName(), scheduleJob.getJobGroup())  
34.                     .withSchedule(schedBuilder).build();  
35.             trigger = TriggerBuilder.newTrigger().withIdentity(scheduleJob.getJobName(), scheduleJob.getJobGroup()).withSchedule(schedBuilder).build();  
36.             scheduler.scheduleJob(jobDetail, trigger);  
37.             log.info(CC.LOG_PREFIX + "新增简单任务："+JasonUtils.Object2String(scheduleJob));  
38.         }else {  
39.             this.updateJobCron(scheduleJob);  
40.         }  
41.     }  

 

需要注意是的，当定时任务只执行一次时，就要仔细看代码，如上面的简单定时任务，刚开始是我这样的：

Java代码  

1. simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue());  

 结果只执行一次，而我需要的是不断循环执行，最后改成：

Java代码  

1. simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue()).repeatForever();  

 

可以看出，后面多了个：repeatForever()，表示永远重复。

 

如果是希望执行多少次后不执行，就使用：.withRepeatCount(triggerRepeatCount)，如下：

Java代码  

1. simpleScheduleBuilder.withIntervalInHours(scheduleJob.getTimeValue()).withRepeatCount(triggerRepeatCount);
