我无法让ProtonCEP根据缺席规则创建事件。
EPA＆＃34; MissingQueueDataRule＆＃34;应该创建一个事件＆＃34; MissingQueueData＆＃34;如果没有类型的事件＆＃34; QueueContextUpdate＆＃34; （事件的entityID不重要）是在过去的时间间隔（30秒）内收到的。
日志中没有明显的错误。

答案 0 :(得分：1)
问题是您的EPA正在使用的时间上下文的发起者是您要查找的QueueContextUpdate事件。由于此事件未到达，因此不会启动上下文......并且EPA根本不活动...
为了测试，我建议将时间上下文的发起者更改为At Startup并尝试再次运行。
稍后，您需要确定此时间上下文的正确定义是什么，以及什么是正确的启动器。也许您想将此时间上下文设置为Sliding Time Window类型？
