如何创建Quartz.NET的工作,需要使用autofac注入

Question

我试图让Quartz.net(2.1.2)使用IoC容器(autofac),因为我需要在预定的作业中使用服务.我在这个主题上找到了类似的帖子,但我似乎找不到一个具有autofac特定注册示例的帖子.

以下帖子涉及我遇到的同一问题:

如何使用Quartz.net 2.0安排任务？

但是,我相信我缺少的那部分是答案说"并且不要忘记在IoC容器中注册作业".我不确定如何准确地做到这一点,因为到目前为止我所尝试的一切都没有奏效.

在下面的示例中,"HelloJob"将运行,但每当我尝试将releaseService注入"ReleaseJob"时,它都拒绝运行.

更新: 我在DependencyRegistration.cs部分标记了我认为问题所在的代码.

更新2: 一些与我需要做的相关的链接可能有所帮助(我已经完成了所有这些但仍然无法弄清楚如何使用autofac):

Answer 1

我终于找到了问题所在.

我的发布服务使用的是一个使用不同范围创建的数据存储库.

我通过创建一个新的测试服务来发现这一点,该服务除了返回一个字符串之外什么也没做,而且它被注入石英作业.

在发现这一点后,我更改了发布服务调用的存储库的范围,然后发布服务在quartz工作中开始工作.

我向任何看过这个问题的人道歉,试图帮助我.因为没有列出发布服务的代码,所以很难弄清楚出了什么问题.

我已经使用autofac用于石英的最终工作绑定更新了代码.
