Quartz动态更新JobDataMap

1. job添加注解@PersistJobDataAfterExecution     @DisallowConcurrentExecution 

@PersistJobDataAfterExecution  
@DisallowConcurrentExecution 
public class FutureMarkJob implements Job{
  
    public void execute(JobExecutionContext context) throws JobExecutionException {  
          
    	JobDataMap jobDataMap = context.getJobDetail().getJobDataMap();
    	System.out.println(FastJsonUtil.fastJsonSerialize(jobDataMap)+"--------------------------");
    	
    	System.out.println(jobDataMap.getString("content")+"--------------------------");
    }  
} 

• @PersistJobDataAfterExecution 表示当正常执行完Job后, JobDataMap中的数据应该被改动, 以被下一次调用时用。
• @PersistJobDataAfterExecution 避免并发造成JobDataMap数据安全问题.

 

2. 更新后JobDataMap替换jobdetail

JobDetail jobDetail = scheduler.getJobDetail("myJob", "myGroup");
jobDetail.getJobDataMap.put("jobQueue", updatedQueue);
scheduler.addJob(jobDetail, true);
