从Config.groovy触发Quartz作业

Question

我在我的应用程序中运行了以下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triggers从Config.groovy文件中设置属性.如果是的话,你能解释一下吗？

我不知道这是否真的有效,因为我不确定什么时候石英作业配置,但理论上它似乎工作.如果您有多个工作,您可能会看到如何使这更加动态.

Config.groovy中

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

BootStrap.groovy中

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

祝好运.如果有帮助,请告诉我.
