问题 What is the best way to disable a job in the JDBCJobStore without deleting it's job or trigger records and without wiping the cron expression? 回答1: Use scheduler.pauseJob() or scheduler.pauseTrigger(). Alternatively you can use the following SQL script: UPDATE QRTZ_TRIGGERS SET TRIGGER_STATE = "PAUSED" 回答2: Use the pauseJob or pauseJobGroup methods of JobStore . 来源： https://stackoverflow.com/questions/4430710/how-can-i-disable-jobs-in-the-quartz-jdbcjobstore

问题 I've a web application which uses framework like Struts and Hibernate. Currently I'm developing a scheduler for this application using Quartz. While coding I realized that the use of Hibernate session is not possible with the threads of Quartz. Anybody have a solution for using hibernate sessions from quartz job class? 回答1: One approach is to use a HibernateUtil class which builds the SessionFactory in a static initializer and makes it available via a public static getter. Your Quartz job can

问题 I remember that we cannot kill the current running Quartz Job but we can interrupt and have a boolean check wherever is necessary whether we need to proceed further with the subsequent operations or not. Even when we implement the InterruptableJob and call the scheduler.interrupt to interrupt the Job, the current executed job will be still running in the server. Ex: A named SQL query has been triggered by the job via Hibernate which takes a long time A call has been made to a third party

问题 I am able to create a taskScheduler in applicationContext.xml, and my job is triggered periodically based on the cron attribute. I would like to change this cron expression(triggering period) after scheduler start, I mean while JavaEE application is running. using Spring 3.XX 回答1: Actually I've faced same issue I am assuming you will need to get date(1-31) , time, day of week ,type of scheduler (Daily , monthly , weeekly ) from user. First, you need to create cron expression from the given

问题 I'm writing a scheduling application in Java using Quartz. I'm using the CronTrigger, but my cron expressions are entered into a database before they are scheduled and are based on user input. Is there a way I can verify that the cron expressions are valid when I capture them? I'd rather do this and give the user an appropriate error message than wait until the scheduler is run and I get a ParseException when I try and create the trigger. Which could be days after the user inputs the data.

问题 Is there a way to have @Scheduled with quartz as the underlying scheduler? Two things that I can think of, but both require some work: create a custom BeanPostProcessor that will parse the @Scheduled annotation and register quartz jobs implement TaskScheduler to delegate to the quartz Scheduler . The question is: is there something already written for the above two options and is there another option? 回答1: I ended up making my own spring-quartz "bridge". I plan on suggesting it as improvement

问题 I send a mail at a specific time using quartz scheduler : static triggers = { cron name: 'DashboardReporting', cronExpression:"0 0 11,20 * * ?" } Now inside execute I send the mail using grails async plugin which works perfectly under run-app mode: emailNotificationService.sendDashboardReportEmail(emaiListing, [model:model,XYZmodel:XYZmodel]) Now this thing works perfectly when I do run-app for development purposes and sends mail from my local machine. But when I run the same code using run

问题 I want to use Global transaction manager at my service layer. eg. namespace AssemblyName.Core.Service.Implementation { public class DemoService { public void demo() { save(model); //This is nHibernate transaction SchedulerManager.GetInstance.save(id); //This is related to quartz. } } } What should I use? If I used TransactionScope() then it is giving me error as NHibernateTransaction can't be committed. I have used <object id="transactionManager" type="Spring.Data.NHibernate

问题 We have a Java application (ESB) that uses quartz 2.2.1 and we use it to schedule hundreds of user jobs. I want to build monitoring page (or scheduler administration page) in my application for our users so that they can see if quartz scheduler is running fine or there is any issue in this component. Does quartz provides any monitoring API for this purpose? Can anyone please tell us what all data points should we show in this monitoring (or administration) page based on your experience? Some
