从 Config.groovy 触发 Quartz 作业

发布于 2024-12-04 11:05:08 字数 951 浏览 1 评论 0原文

我的应用程序中正在运行以下 Quartz 作业:

class ScraperJob {
    def scraperService

    static triggers = {
        cron name: 'scraperTrigger', cronExpression: "0 0 * * * ?"  // run every minute
    }

    def execute(){
        try {
            scraperService.storing()
            log.info "${new Date()} - Scraping went smoothly."
        }
        catch(IOException) { // Connexion problem
            log.error "${new Date()} - Method: parsing >> Connexion down or interrupted while parsing !"
        }
        catch(SAXException) { // Any SAXParser exception
            log.error "${new Date()} - Method: parsing >> Parser error."
        }
        finally { // if not closed, the application crashes when the connexion fails
            scraperService.slurper.finalize()
            scraperService.parser.finalize()
        }
  }
}

我想知道是否可以从 Config.groovy 文件设置 triggers 属性。如果是的话,你能解释一下怎么做吗?

I have the following Quartz job running in my application:

class ScraperJob {
    def scraperService

    static triggers = {
        cron name: 'scraperTrigger', cronExpression: "0 0 * * * ?"  // run every minute
    }

    def execute(){
        try {
            scraperService.storing()
            log.info "${new Date()} - Scraping went smoothly."
        }
        catch(IOException) { // Connexion problem
            log.error "${new Date()} - Method: parsing >> Connexion down or interrupted while parsing !"
        }
        catch(SAXException) { // Any SAXParser exception
            log.error "${new Date()} - Method: parsing >> Parser error."
        }
        finally { // if not closed, the application crashes when the connexion fails
            scraperService.slurper.finalize()
            scraperService.parser.finalize()
        }
  }
}

I would like to know if it is possible to set the triggers property from the Config.groovy file. If it is, could you explain how?

我不知道这是否真的有效,因为我不确定石英作业何时配置,但理论上它似乎有效。如果您有不止一份工作,您可能会看到如何让这变得更有活力。

Config.groovy

quartz.yourCronJobName="0 0 * * * ?"

BootStrap.groovy

import org.codehaus.groovy.grails.commons.ConfigurationHolder as ConfigHolder
...
def cronExpression = ConfigHolder.config.yourCronJobName
ScraperJob.triggers.cronExpression = cronExpression 

祝你好运。如果有帮助请告诉我。

I have no idea if this would actually work because i'm not sure when the quartz jobs get configured but in theory it would seem to work. You could probably see how you could also make this much more dynamic if you have more than one job.

Config.groovy

quartz.yourCronJobName="0 0 * * * ?"

BootStrap.groovy

import org.codehaus.groovy.grails.commons.ConfigurationHolder as ConfigHolder
...
def cronExpression = ConfigHolder.config.yourCronJobName
ScraperJob.triggers.cronExpression = cronExpression 

Good luck. Let me know if it helps.

这是我最终的做法:

Config.groovy

scraperJob= "0 * * * * ?"

ScraperJob.groovy

import org.codehaus.groovy.grails.commons.ConfigurationHolder as ConfigHolder

class ScraperJob {

  static triggers = {
        cron cronExpression: ConfigHolder.config.scraperJob // Calling the ScraperJob set in Config.groovy
    }
  def execute(){ ... }
}

Here is how I eventually did it:

Config.groovy

scraperJob= "0 * * * * ?"

ScraperJob.groovy

import org.codehaus.groovy.grails.commons.ConfigurationHolder as ConfigHolder

class ScraperJob {

  static triggers = {
        cron cronExpression: ConfigHolder.config.scraperJob // Calling the ScraperJob set in Config.groovy
    }
  def execute(){ ... }
}
