我正在尝试执行一系列作业,其中一个作业执行另外两个,其中一个执行另一个。
Job 1 --> Job 3
--> Job 2 -->Job 4
作业用于从db发送数据。 这就是我所做的
@PersistJobDataAfterExecution
@DisallowConcurrentExecution
public class MembersJob implements Job{
List<Member>unsentMem=new ArrayList<Member>();
JSONArray customerJson = new JSONArray();
Depot depot;
public MembersJob(){
depot = new UserHandler().getDepot();
}
public void execute(JobExecutionContext jec) throws JobExecutionException {
if ( Util.getStatus() ){
runSucceedingJobs(jec);
} else {
System.out.println("No internet connection");
}
}
public void runSucceedingJobs(JobExecutionContext context){
JobDataMap jobDataMap = context.getJobDetail().getJobDataMap();
Object milkCollectionJobObj = jobDataMap.get("milkCollectionJob");
MilkCollectionsJob milkCollectionsJob = (MilkCollectionsJob)milkCollectionJobObj;
Object productsJobObj = jobDataMap.get("milkCollectionJob");
ProductsJob productsJob = (ProductsJob)productsJobObj;
try {
milkCollectionsJob.execute(context);
productsJob.execute(context);
} catch (JobExecutionException ex) {
System.out.println("Error...");
Logger.getLogger(MembersJob.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
串联呼叫
//Members Job
JobKey membersJobKey = new JobKey("salesJob", "group1");
JobDetail membersJob = JobBuilder.newJob(MembersJob.class)
.withIdentity(membersJobKey).build();
membersJob.getJobDataMap().put("milkCollectionJob", new MilkCollectionsJob());
membersJob.getJobDataMap().put("productsJob", new ProductsJob());
//
CronTrigger membersTrigger = newTrigger()
.withIdentity("salesTrigger", "group1")
.withSchedule(
cronSchedule("0/10 * * * * ?"))
.forJob(membersJobKey)
.build();
Scheduler scheduler = new StdSchedulerFactory().getScheduler();
scheduler.scheduleJob(membersJob, membersTrigger);
scheduler.start();
问题是成员工作开始但在完成时不会启动其他工作。实现这一目标的最简单,最快捷的方法是什么?
