Hi, I need to write a service where jobs can be added and should executed
after a given delay. After execution they are finished, so periodical
execution is not required. I prefer to user the ScheduledExecutorService
for this task.
The question is now, how do I use my @Inject objects in the thread? Just
passing them is not working (hibernate session is invalid). I read some
stuff like http://wiki.apache.org/tapestry/Tapestry5HowToRunTaskInThreadbut it
does'nt help me because I don't invoke the thread myself, the
scheduler is doing it. Also the other tapestry classes like the
ParallelExecutor or PeriodicExecutor doesn't seem to fit.
Any suggestions?
@Scope(ScopeConstants.DEFAULT)
public class MyServiceImpl implements MyService {
@Inject
MyDAO myDAO;
private ScheduledExecutorService scheduler = Executors.
newScheduledThreadPool(4);
public void addJob(Job job, long executeDelay) {
scheduler.schedule(new JobTask(job, myDAO), executeDelay);
}
public static class JobTask implements Runnable {
// some class members
public JobTask(MyDAO myDAO, Job job) {
this.myDAO = myDAO;
this.job = job;
}
@Override
public void run() {
// ...
Object result = myDAO.getSomethingFromJob(job);
// ...
}
}
}
Thanks,
Matthias
