quartz-scheduler

问题 i have an quartz job in my web-application, which is started by an servlet. When i redeploy my application i get following message [DefaultQuartzScheduler_Worker-5] but has failed to stop it. This is very likely to create a memory leak Also in production we have the problem that the tomcat-server doesn't stop after ./shutdown.sh, so that we have to kill the process. In my opinion it depence on the quartz job, that can't stop. How can i stop the quartz job by redeploy my application or

问题 I'm not quite sure whether this is more of an Openbravo issue or more of a Quartz issue, but we have some manual processes that run on schedules via Openbravo ProcessRequest objects (OB v2.50MP24), but it seems that the processes are running twice, at the exact same time. Openbravo extends the Quartz platform for their scheduling. I've tried to resolve this issue on my own by ensuring that my process classes extend this class: import java.util.List; import org.openbravo.dal.service.OBDal;

问题 I am trying to run the sample helloworld program for quartz scheduling given on roseindi.net http://www.roseindia.net/quartz/quartz-scheduler-tutorial.shtml I have both the classes given there exactly similar setup in my java projecy with quartz version 1.6 - all.jar in the project library. When I try to run the application I get the following Exception Exception in thread "main" java.lang.NoClassDefFoundError: javax/transaction/UserTransaction at org.quartz.impl.StdSchedulerFactory

问题 I used Quartz as scheduler in my application. Trying to use Spring boot 2.0 features. I have 2 different data sources in the configuration. One for application and another one for scheduler. How can I use non-primary data source (schedulerDataSource in this case) as data source for Quartz? Please help. pom.xml <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.0.RELEASE</version> </parent> <dependencies> <dependency> <groupId

问题 I need to run a job on the last day of every month. i tried the following cron expression: <property name="cronExpression" value="0 0 3 L * * *" /> but got this error: Caused by: java.lang.UnsupportedOperationException: Support for specifying both a day-of-week AND a day-of-month parameter is not implemented. it doesnt like the L , but without using it, how can i run on the last day of the month? 回答1: Just change your trigger to 0 0 3 L * ? One of day of week or day of month needs to be ? .

问题 I am using the Quartz Scheduling API for Java. Could you help me to run every 25 seconds using cron-expression. It's just a delay. It does not have to start always at second 0. For example, the sequence is like this: 0:00, 0:25, 0:50, 1:15, 1:40, 2:05, etc until minute 5 when the sequence begins again at second 0. Thank you. 回答1: I don't think cron expression will allow you to do that, but you can use SimpleScheduleBuilder.repeatSecondlyForever( 25 ) as 300 (5 minutes) is a multiple of 25 it

问题 I'm using quartz in my project. My web application has apparently caused a memory leak when it stops, the error is : SEVERE: A web application appears to have started a TimerThread named [Timer-12] via the java.util.Timer API but has failed to stop it. To prevent a memory leak, the timer (and hence the associated thread) has been forcibly cancelled.

问题 I am new to batch processing. I am trying to start with simple scheduler and job. But i am confused b/w spring batch vs quartz jobs. My understanding is Quartz :- quartz provides both frameworks i.e scheduler framework and job framework(in case I do not want to use spring batch jobs). Right ? Spring Batch :- It only provides the job framework . I have always send using Quatz schecduler to schedule spring batch jobs. Does spring provides its own scheduler also ? 回答1: Quartz is a scheduling

问题 In an application, since I converted it from a classical Spring webapp (deployed in a system Tomcat) to a Spring Boot (V1.2.1) application I face the problem that the Quartz-based scheduled jobs are not working anymore. I schedule these Quartz jobs like this: // My own Schedule object which holds data about what to schedule when Schedule schedule = scheduleService.get(id of the schedule); String scheduleId = schedule.getId(); JobKey jobKey = new JobKey(scheduleId); TriggerKey triggerKey = new

问题 I'm using Spring to inject a Quartz scheduler (abstracted with Spring's TaskScheduler interface) into my app that loads jobs configured from a database at startup. It adds each job in the scheduler something like this: TaskScheduler taskScheduler = ...;//injected Runnable runableThing = ...; String cronExpression = ...; //from DB taskScheduler.schedule(runableThing, new CronTrigger(cronExpression)); my question is this: Is it possible to specify something like a job_id that can subsequently
