How to get JobKey / JobDetail of Quartz Job

天涯浪子 提交于 2019-12-01 09:04:06
I'm having trouble to understand how I can get the details of a job with Quartz version 2.3.2. Until now, we used Quartz v1.0.x for jobs and I have to upgrade it to the latest version. This is how we used to get the details of a job: JobDetail job = scheduler.GetJobDetail(task.Name, groupName); With version 2.3.2, the method GetJobDetail() doesn't have a constructor that takes 2 parameter anymore... instead, it takes a JobKey parameter. Unfortunately I couldn't find a way to get a single JobKey. What I tried is the following: string groupName = !string.IsNullOrEmpty(task.GroupNameExtension) ?

Quartz: How to reload jobs and triggers with org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin?

问题 I want to use quartz in my small and simple web application. (Quartz 2.1.6 and tomcat 7.0.22). I want to change trigger cron expression without restart my application.

I see it in log file. But content of this file is old (the same as it will on startup). So i have

Quartz.NET - Using/understanding cron based trigger and time zone/summertime (daylight saving time)

For sake of an example lets use the following cron expression: "0 0 14 1 * ?" -> Fire on the 1st day of every month at 14:00 hours. I used the Quartz CronScheduleBuilder to build the expession, but this is irrelevant. My Local timezone is UTC+01:00 and the summertime (this year) begins on 31.03.2013 2:00, where the time is adjusted to 3:00. When i schedule a new Job using the proposed trigger on lets say 20.02.2013, Quartz calculates the System.DateTimeOffset for the "NextFireTimeUtc" correctly to: DateTime: 01.03.2013 13:00:00 (this is the UTC time, which is one hour behind the local timezone

Using Quartz in a clustered environment

自作多情 提交于 2019-12-01 07:09:23
问题 I'm looking to use the quartz scheduler in my application because I have a clustered environment and want to guarantee that only one instance of my job runs each hour. My question is...Do I have to use a JDBC job store or some sort of "outside" storage of job data to guarantee that only once instance in my cluster runs the job at any given hour or is there more magic to Quartz that I am aware of? 回答1: Yes, you need to use the JDBC-JobStore, or else the TerracottaJobStore to enable a mechanism

Java Excel POI stops after multiple execution by quartz

你说的曾经没有我的故事 提交于 2019-12-01 06:34:36
I'd like to have a couple of insights on this. I have a program that reads and writes from a database to an excel file. It's execution is based on a timer using Quartz api and triggered every tuesday of the week. The problem is, when i tested it by scheduling it to execute the job every hour, the program suddenly stops after a few executions inside the process of writing the excel file. Here is my write to excel code. try { FileInputStream file = new FileInputStream(excelFile); POIFSFileSystem myFileSystem = new POIFSFileSystem(file); HSSFWorkbook workbook = new HSSFWorkbook(myFileSystem);

Quartz scheduler vs setting up cron

Was planning to move from setting up cron jobs to Quartz scheduler. What are the pros/cons of using Quartz rather than setting up cron ? Got this Time triggered job Cron or Quartz? link. Any other pointers ? I have used and like quartz. Here are some advantages of quartz If you use an OS based cron the jvm would go up and down and any state would be lost. it is portable (can run on Win OS where no cron available) You can schedule multiple threads within quartz We run our scheduler in tomcat and so we can manage and see the state of the app via admin web pages. In our app we use jamon to

Create a Quartz.NET Job with several constructor parameters

六眼飞鱼酱① 提交于 2019-12-01 04:16:08
I have a job which needs to kick off some methods on another object. I'd like to be able to pass these into the job in its constructor. Looking around, it seems that the only way to achieve this is to use one of IoC frameworks. Whilst this method will be a solution for me in the future, right now I need a vanilla solution, not requiring any IoC. I am aware of the JobDataMap but the Best Practices documentation advises against this due to serialization. The object is multi-threaded and statefull, so serializing would be code suicide anyhow. How can I create a job similar to below: public class
