Sql server 2012 Can'；不要关闭ServiceBroker对话

我在结束ServiceBroker对话时遇到问题，我想从概念上理解事情应该如何运作。 请注意，我的代码基于Dan Guzman的示例

给定以下SQL Server 2012 Service Broker配置：

• 发起者
• 启动器服务-内部激活
• 目标
• 目标队列监视器
• 外部激活器服务（与REST服务通信的SSIS应用程序）

这是我对流程的理解：

发起程序向目标发送消息

目标队列通知事件激发

外部激活器服务执行以响应目标队列通知事件；问题接收TOP（1）以检索发送到目标的消息

External Activator服务完成处理并执行END CONVERSATION@ConversationHandle

步骤4的结束对话会向发起人发送一条关闭消息；启动器的内部激活服务运行以响应启动器队列中出现的消息，进行处理并发出END CONVERSATION@ConversationHandle

不幸的是，对话的发起方结束了，但目标方从未结束；它处于断开连接的状态

当External Activator服务发出END conversation@ConversationHandle时，会话的目标端不会关闭吗？如果没有，如何结束对话的目标端

        -- means that the service can initiate conversations
        -- but it can't be a target for any other services

这里有两个对话。一个是您自己的应用程序对话，一个是通知EA的系统对话。从您描述代码的方式来看，您依赖EA来关闭对话，但这只会关闭系统对话。您还需要关闭应用程序对话，即从目标队列接收的句柄

更新：

您激活的服务应发出<代码>接收。。。从目标，然后在收到的@handle上结束对话。你的解释说这就是你要做的（第4步），但如果你这样做，那么目标对话将在30分钟内彻底结束

但是，您注意到会话处于断开连接的入站状态。这是一个已收到EndDialog消息但应用程序未对其发出结束转换的对话

---

因此，您所解释的应用程序正在执行的操作与观察到的对话状态之间存在脱节。我猜代码中可能有一个bug，而代码并没有完全按照您认为的那样执行。请尝试在此处发布代码的相关部分。

感谢您的回复。如果EA服务发出END CONVERSATION@ConversationHandle不足以关闭应用程序对话，我将在何处执行END CONVERSATION以关闭我的应用程序对话。你能给我举个例子吗？在

pci\u GetABCEventDetails

中，你从

ABCEventTargetQueue

中退出队列，插入

ABCEventTransferLog

并提交。在

pci\u CompleteABCEventTransfer

中，您可以结束对话，但不清楚是否传入了正确的对话句柄。
