Question

流程订单：

Saga消息处理程序接收包含数据项的第一条消息。
消息处理程序使用具有自己的数据库事务的业务对象。
如果项目已更新，则数据库事务提交和saga完成。
Saga消息处理程序接收包含数据项的第二条消息。
如上所述，消息处理程序抛出异常尝试打开新数据库事务。

错误讯息：

System.Data.SqlClient.SqlException (0x80131904): Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.

上面有很多代码涉及上述流程，但我很乐意发布有用的内容。

Answer 1

我剥离了事务，发现传奇处理程序正在打开另一个数据库连接，默认情况下，连接已在DTC中登记。我在连接字符串中添加了“Enlist = false”，因为数据库抛出的异常需要被捕获并相应地处理，而不是折叠分布式事务。现在它的行为符合预期。

感谢您的意见，我将重新审视代码并在船上发表您的意见。
