grails动态定时任务

安装两个插件：grails install-plugin quartz, grails install-plugin quartz-monitor

我对quartz-monitor做了简单汉化（取消i18n，增加jquery.js，汉化直接在js文件中完成，附件有下载）

创建动态任务

def myTrigger = new CronTriggerImpl()
myTrigger.setName("myTrigger_test")
myTrigger.setCronExpression('2 * * * * ?')
Test1Job.schedule(myTrigger)

创建任务：grails create-job Test1

class Test1Job {
    static triggers = {
    }
    def execute() {
        // execute job
        println('hello quartz!')
    }
}

上面的方法，是可以添加简单定时任务，若要给Test1Job传参数，那么写法变成

Test1Job.schedule("cronExpression", Map)

Test1Job {

  execute(context)

}

但这种方法，还不清楚如何注入triggerName，因为triggerName是quartz的唯一标记。

查找triggerName

def listJobGroups = quartzScheduler.getJobGroupNames()
        listJobGroups?.each { jobGroup ->
            quartzScheduler.getJobKeys(jobGroupEquals(jobGroup))?.each { jobKey ->
                def jobName = jobKey.name
                List<Trigger> triggers = quartzScheduler.getTriggersOfJob(jobKey)
                if (triggers) {
                    triggers.each { trigger ->
                        println("name:" + trigger.key.name)
                    }
                }
            }
        }
