问题 I am using Quartz Scheduler with my spring 3.0 based application. I am successfully able to create new schedulers and they are working fine. I have seen thus reference. But.. I am not able to retrieve servletContext in my quartz job file. can anyone help me for How to retrieve servletContext reference in executeInternal() method ?? Gunjan Shah, thx. 回答1: I had a similar need. I sorted it out in a similar fashion to the solution presented here. In my servlet context listener I am setting the

问题 I have some questions about Quartz clustering, specifically about how triggers fire / jobs execute within the cluster. Does quartz give any preference to nodes when executing jobs? Such as always or never the node that executed the same job the last time, or is it simply whichever node that gets to the job first? Is it possible to specify the node which should execute the job? 回答1: The answer to this will be something of a "it depends". For quartz 1.x, the answer is that the execution of the

问题 I have a spring integration flow triggered by the cron expression like follows: <int-ftp:inbound-channel-adapter id="my-input-endpoint" ...> <int:poller trigger="my-trigger"/> </int-ftp:inbound-channel-adapter> <bean id="my-trigger" class="org.springframework.scheduling.support.CronTrigger"> <constructor-arg value="0 * * * * *" /> </bean> It works fine. But now I have to extend the implementation to make it cluster ready (job execution on only one cluster node at the same point of time). My

问题 I have ASP.NET MVC 3.0 application, with EF Code First for data layer. I have implemented a Unit of work pattern, I’m binding context of the unit of work on HttpContext.Current.Items[SomeKey] collection. Unit of work is created and committed in OnActionExecuting/Executed events on controller. I’m instantiating repositories using Windsor Castle. Now I need to use Quartz.net to run a job periodically in my app, this job need also use few repositories. The problem is, that in a SchedulerJob

问题 Where is the documentation for quartz xml files (specifically jobs.xml)? I found the javadoc online, but I can't seem to find the documentation for how to write an xml file, just some brief examples e.g. this one from O'Reilly. edit: apparently the java class that reads the jobs.xml is JobInitializationPlugin, but I don't see the docs for the xml format there either. 回答1: This is really poorly documented. Beyond the brief mention at the OpenSymphony site, the only documentation comes in the

问题 I am just can figure out how to configure a Cron job in Quartz with initial delay. So i need something that runs every hour with an initial delay of 10 min. "* * 0/1 * * ?" 回答1: Here's a late answer, hopefully this helps others. I solved the issue by having 2 scheduled functions in my service class: @EnableScheduling public class DeviceService { @Scheduled(initialDelayString = "${devices.update.initial}", fixedDelay = 2592000000L) public void initialUpdateDevices() { updateDevices(); }

问题 I have a Spark job which reads an HBase table, some aggregations and store data to mongoDB. Currently this job is running manually using the spark-submit script. I want to schedule it to run for a fixed interval. How can I achieve this using java. Any library? Or Can I do this with Thread in java? Any suggestions appreciated! 回答1: If you want to still use spark-submit I would rather prefer crontab or something similar and run bash script for example. But if you need to run "spark-submit" from

问题 I've achieved configuring CronExpression from a propery file, but this property file is apache-deltaspike.properties, which is inside the .jar file. I need to take the cron expression from my custom config file: import org.apache.deltaspike.core.api.config.PropertyFileConfig; public class myOwnPropertyFileConfig implements PropertyFileConfig { private static final long serialVersionUID = 1L; @Override public String getPropertyFileName() { return "cfg/myOwnPropFile.properties"; } @Override

问题 Starting from the Jan 1st 2014 the 2 week periods yield the following schedule: Jan 14 Jan 28 Feb 11 Feb 25 Mar 11 Mar 25 Apr 8 Apr 22 May 6 May 20 etc ... This is not an idle question. Some companies have exactly 2 week long pay periods, meaning they have 26 pay periods per year rather than 24 for a company that pays twice a month as opposed to every two weeks exactly. I want to know whether I can express the pay schedule of such a company using a CRON expression. Finally, it is possible

问题 In my application, quartz job is scheduled as soon as the application is deployed. I have two log files home-log-search.log and home-log-app.log , both for specific logging. Search log file is only to log the visitor's IP and rest all logging (exception, debug info) are logged in App log file. The problem which i am facing is, the default Quartz statements are getting logged in home-log-search.log file which is not required. How can i disable that logging? Setting level to OFF doesn't worked.
