Question

我正在建立一个系统，用户可以请求异步运行任务。

我将这些任务存储在Grails Domain Class ScheduledTask 的表格中。

我有两个Quartz Jobs

的 CheckForScheduledTasksJob
- 每30秒触发一次
的 RunActionJob
- 需要时根据需要触发
- （将来会有一系列可配置的数量。）

目前代码流程为：

CheckForScheduledTasksJob

CheckForScheduledTasksJob {
    void execute() {
        taskService.checkForScheduledTasks()
    }
}

TaskService

void checkForScheduledTasks() {
    ScheduledTask scheduleTask = getNextPendingTask()

    if (scheduleTask) {
         Map params = [ scheduleTask:scheduleTask ]
         RunActionJob.triggerNow(params)
    }
}

此时我收到以下错误：

| Error 2014-01-02 15:00:01,112 [quartzScheduler_QuartzSchedulerThread] ERROR core.ErrorLogger  - An error occurred while scanning for the next triggers to fire.

RunActionJob 的代码仍在开发中。到目前为止看起来像是：

class RunActionJob implements InterruptableJob, Serializable {
    boolean interrupted = false

    static triggers = {
    }

    void execute(JobExecutionContext context) {
        log.info ("HERE " + (new Date()))

        ScheduledTask task = context.getMergedJobDataMap()?.scheduleTask 

        return
    }

    void interrupt() {
        interrupted = true
    }

}

提前感谢您的任何帮助或回复。

通过反复试验，我最终发现这个问题的原因是在params中传递了ScheduledTask类。我认为该类存在序列化错误。

如果我只是在params中传递ScheduledTask.id，然后将id转换为RunActionJob中的完整对象，那么一切都按预期开始工作。

使用Grails触发立即Quartz作业时触发错误
