The job reads a file from a folder( which has multiple files ) does some processing and copies it to another folder. is it possible to create multiple instances of the job, that will run concurrenty,reading multiple files ? My question is : In spring batch, is it possible to spawn multiple instances of the same job? I am using quartz schedular ? 回答1: In Spring Batch it is possible to start several jobs, provided you have supplied different

问题 I have some problems understanding the DateTimeOffset... I am trying to create a simple-trigger for a Quartz-Job. There exists a triggerbuilder with which one can create such a trigger like this: var triggerbuilder = TriggerBuilder.Create() .WithIdentity(triggerName, ConstantDefinitions.InternalDefinitions.AdhocJobGroup) .StartAt(new DateTimeOffset(scheduledTime)); The scheduledTime is a DateTime. Let's say it is new DateTime(2014, 10, 15, 14, 0, 0); I live in a city which lies in the Central

问题 This is my config for nlog. What i'm trying to achieve is to have Quartz logs in separate file. But checking the logs folder i find only scheduler log file. <targets> <target xsi:type="File" name="f" fileName="${basedir}/logs/log-${shortdate}.log.json" layout="${json}" /> <target xsi:type="File" name="scheduler" fileName="${basedir}/logs/log-${shortdate}.scheduler.log" layout="${message}" /> <target xsi:type="Console" name="console" layout="${longdate} ${uppercase:${level}} ${message}" /> <

问题 I'm trying to write a cron expression for quartz that runs hourly everyday except every second Saturday of the month. So, by using the '#' notation, I was trying to write the expression like: 0 0 * ? * SUN-FRI,SAT#1,SAT#3,SAT#4,SAT#5 This expression is not working properly. Also, quartz is not complaining about the cron format (quartz usually complains about cron expressions when they are wrong). So I did some other experiments today. So, today is the third Thursday of the month, I was

问题 I am developing an application that gives the user the ability to schedule some activity. Inputs that are provided by user are Value of N Option amongst Hour/Day/Week/Month Start Date Start Time I am unable to get the cron expressions right for each of the repeat interval type i.e. Hour/Day/Week/Month so that the trigger time is calculated from the start date. 回答1: Quartz documentation suggests using a SimpleTrigger http://www.quartz-scheduler.org/docs/cookbook/BiDailyTrigger.html, an example

问题 I have a quartz configuration section in my web.config, and I want to add a key value field to it. (I know I can just go to the web.config and add it manually but that defeats the purpose) I tried using this way var config = (NameValueCollection)WebConfigurationManager.GetSection("quartz"); config.Add("quartz.dataSource.quartzDS.connectionString", "data source =.."); but it failed because collection is read only and can't be modified. Any tip to how to do this? Edit: I ended up copying the

问题 I am trying to measure application and jvm level metrics on my application using DropWizard Metrics library. Below is my metrics class which I am using across my code to increment/decrement the metrics. I am calling increment and decrement method of below class to increment and decrement metrics. public class TestMetrics { private final MetricRegistry metricRegistry = new MetricRegistry(); private static class Holder { private static final TestMetrics INSTANCE = new TestMetrics(); } public

问题 I have an application using Grails Quartz plugin. I need to have two jobs to have multiple instances running, but have separate limitation on number of threads to be used for each job. As far as I understand, I need separate Thread Pools, which is possible by having separate schedulers. However, I cannot figure out how to create multiple schedulers with Quartz plugin. 回答1: Assuming you want to use different triggers to start the job multiple times. this works for me. class MyJob { static

问题 i need to run a class from quartz-schedualer, and i need it to be running always and parallel form the main app. The class will always be cheking for new files in a folder to process. I though to include it as a listener in the web.xml, how ever this way the constructor does not run, only the calss is loaded. Any sugestions ? Here what i added in the web.xml: <listener> <listener-class>com.bamboo.common.util.QuartzSchedualer</listener-class> </listener> This is how i declared the class:

问题 I'm trying to implement scheduler to my application. I use spring and quartz support. I have test my component and run perfectly.
