Quartz.Net 并在链接作业之间传递数据 [英] Quartz.Net and passing data between chaining jobs

问题描述

我必须实现一个简单的工作流程.

I've got to implement a simple workflow.

某些作业 A 必须在指定时间运行(cron 触发器).此作业搜索未处理的数据(比如一些 IThingToDo[])并对其进行处理.作业 B 必须在作业 A 完成后立即执行，并且应将已处理数据列表 (IThingToDo[]) 传递给它.

Some job A have to run at specified time (cron trigger). This job searches for unprocessed data (let's say some IThingToDo[]) and process it. Job B has to be performed just after job A finished and the list of processed data (IThingToDo[]) should be passed to it.

作业 A 存储数据如下:

Job A stores data like this:

context.Put("Things", things);

然后我使用 IJobListener 知道作业 A 何时完成，获取事物"数组并为作业 B 创建触发器:

Then I use IJobListener to know when job A finished, get the "Things" array and create a trigger for job B:

Trigger trigger = new SimpleTrigger("JobBTrigger", "NS", DateTime.Now);
trigger.JobName = "JobB";
trigger.JobGroup = "NS";
trigger.JobDataMap.Put("Things", things);
context.Scheduler.ScheduleJob(trigger);

这很好用.除了我无法从作业 B 中获取事物"，context.Get("Things") == null.

This works fine. Except that I can't get "Things" from job B, context.Get("Things") == null.

怎么了?

推荐答案

我找到了答案.我只需要使用 MergedJobDataMap(它是来自 JobDetail 和触发器的组合 JobDataMap):

I've found an answer. I just had to use MergedJobDataMap (which is a combined JobDataMap from a JobDetail AND a Trigger):

var things = context.MergedJobDataMap.Get("Things");
