Grails - Quartz作业触发器中的参数 [英] Grails - Parameter in a Quartz job Trigger

问题描述

  class UserMonthlyNotificationJob {
 static triggers = {
 cron name：'dailyTrigger'，cronExpression：...
 cron名称：'weeklyTrigger'，cronExpression：...
 cron名称：'monthlyTrigger'，cronExpression： ...
} 
 
 def execute（）{...} 
} 
  

我希望能够在 execute 块中提供的触发器中设置一个参数。
似乎我无法在 cron触发器中设置任何变量，并且自定义触发器需要执行 Quartz Trigger接口，我不知道该怎么做。

非常感谢任何帮助。

解决方案

让你的工作实现 StatefulJob ，那么你就可以访问 JobExecutionContext ，它有一个触发器实例访问器。如果你有自己的Trigger类，那将是它的一个实例。

I have the following quartz job, set via Quartz-plugin:

class UserMonthlyNotificationJob { 
static triggers = {
        cron name:'dailyTrigger', cronExpression: " ... "
        cron name:'weeklyTrigger', cronExpression: " ... "
        cron name:'monthlyTrigger', cronExpression: " ... "
}

    def execute(){ ... }
}

I would like to be able to set a parameter in the trigger that would be available in the execute block. It seems I can not set any variable in a cron trigger, and a custom trigger require to implement the Quartz Trigger interface, which I do not know how to do.

Any help greatly appreciated.

解决方案

Make your job implement StatefulJob, then you'll have access to JobExecutionContext which has a Trigger instance accessor. If you have your own Trigger class, that will be an instance of it.
