我可以通过并处理相同的消息来启动 NserviceBus 传奇吗? [英] Can I have a NserviceBus saga be started by AND handle the same message?

问题描述

快速问题:我有一个传奇，它可以有一个场景，它需要处理可能在两种情况下出现的消息.一种是传奇仍处于打开状态，另一种是传奇已被标记为完成.

Quick question: I have a saga that can have a scenario where it needs to handle a message that could come in under two situations. One where the saga is still open and one where the saga has been marked as complete.

如果传奇是开放的，太好了，照常继续.如果传奇没有打开，它需要开始一个新的传奇.处理这种情况的最佳做法是什么?IHandleMessages<> 效果很好，显然，如果传奇是开放的.但是 IAmStartedByMessages<> 不会导致两个传奇打开吗?这会很糟糕.谢谢

If the saga is open, great, continue as normal. If the saga is not open it needs to to start a new saga. What is the best practice to handle this situation? IHandleMessages<> works great, obviously, if the saga is open. But won't IAmStartedByMessages<> cause two sagas to be open? This would be bad. Thanks

推荐答案

IAmStartedByMessages<> 如果可以解决已打开的 saga，则不会导致打开 2 个 saga.您应该可以只使用 IAmStartedByMessages<> 而无需 IHandleMessages<>.

IAmStartedByMessages<> will not cause 2 sagas to be open if an already open saga can be resolved. You should be fine to just use IAmStartedByMessages<> with no need for an IHandleMessages<>.
