quartz-scheduler

问题 I am developing a web app where batch programs need to run for specific times. I used Quartz library to schedule the jobs. The web app is deployed on Websphere 8.5.5 and its working fine, accessing the tables through datasources (Datasource given in code is java:comp/env/jdbc/db_datasource ). The job is also triggered at the mentioned times. I am getting an error when the scheduled job makes a DB connection through the datasource and the error is: javax.naming.ConfigurationException: A JNDI

问题 I have three environments dev, stg and prod server. I have a microservice project which is having quartz scheduler for sending daily report as email. The quartz configuration is as given below: Now the issue is that I want the quartz scheduler for sending daily report mail to register and run only on prod environment server. I dont want the scheduler to execute under stg and dev environment server. I am using AWS ec2 instances for environment server Can anyone please tell me how to do this.

问题 We need to monitor the status of quartz jobs by only having access to the database. Does quartz offer a way to achieve this? Reading the documentation, in the Trigger class we have TriggerState which defines various states, ERROR and COMPLETE among others. But during regular execution, the CompleteExecutionInstruction is always NOOP. It doesn't matter if I throw an exception or execute completely. I was expecting something like COMPLETE if I was successful or ERROR if I threw an exception.

问题 I wrote this method to remove a job from Quartz JDBC public boolean removeJob(String jobName) { try { JobKey jobKey = JobKey.jobKey(jobName); try { Scheduler sched = schedulerFactoryBean.getScheduler(); logger.info("RESULT: " + sched.deleteJob(jobKey)); } catch (Exception e) { throw new RuntimeException(e); } return true; } catch (Exception ex) { logger.error(ex.getMessage()); return false; } } deleteJob is always returning false . So the job is not getting removed from the JDBC tables in

问题 I am trying to run Quartz Scheduler using SpringBoot. Using Quartz Jdbc Data Store. Due to security reasons , we wish to pick the Db credentials from the properties file. From what I understand from here(Using env variable in Spring Boot's application.properties) and springBoot docs, SpringBoot automatically replaces environment variables in application.properties but I am not seeing this . Here is my system environment file which i am sourcing before running the application export DB_HOST

问题 I need to create a Quartz cron expression that fires every 10th day of the month if it is a weekday , otherwise fires to the next day or the day after the next. E.g. August 10th 2014 is Sunday, fire Monday 11th E.g. September 10th 2014 is Wednesiday, fire Wednesday 10th E.g. January 10th 2015 is Saturday, fire Monday 12th I highlighted the third case: I tried 0 0 0 10W * ? as expression but it fires Friday Jan 8th 2015. I need it to be fired later. How do I tell Quartz to? I wanted to make

问题 I am sorry if this question is too naive, I am expecting the jobs to be scheduled so that it executes one by one, and not parallely.It is executed only once. From docs, @DisallowConcurrentExecution is An annotation that marks a {@link Job} class as one that must not have multiple instances executed concurrently (where instance is based-upon a {@link JobDetail} definition - or in other words based upon a {@link JobKey}). But when I schedule a job with same JobKey, I am getting Failed to

问题 my database having 10 18 16 ? * SUN,MON,WED,FRI * cron expression then how to convert into Java date. how to comparing with present day time. and one more is how to compare to cron expressions i.e. 10 18 16 ? * SUN,MON,WED,FRI * and 0 30 9 30 * ? please explain the sample code using quartz or spring scheduling. 回答1: Please use: import org.springframework.scheduling.support.CronSequenceGenerator; final String cronExpression = "0 45 23 * * *"; final CronSequenceGenerator generator = new
