从 Config.groovy 触发 Quartz 作业 [英] Quartz job triggering from Config.groovy
问题描述
我的应用程序中正在运行以下 Quartz 作业:
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()
}
}
}
我想知道是否可以从 Config.groovy
文件中设置 triggers
属性.如果是,你能解释一下吗?
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?
推荐答案
我不知道这是否真的有效,因为我不确定何时配置石英作业,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件事变得更有活力.
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
Config.groovy
quartz.yourCronJobName="0 0 * * * ?"
BootStrap.groovy
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.
Good luck. Let me know if it helps.
