【中文标题】未登录 MassTransit Mediator 的异常

【英文标题】：Exception not logged in MassTransit Mediator

【问题描述】：

我们已连接 MassTransit Mediator，以将消息散播到 MassTransit 消费者。但是，如果这些消费者中的任何一个引发异常，则该异常不会记录到日志中。

以下是日志示例：

如何配置 Masstransit Mediator 以将异常消息记录到控制台（我确定 MassTransit+RabbitMQ 默认会发生这种情况？）

谢谢

修复更新：

所以没有记录异常的问题来自aws-logging-dotnet包，默认情况下它不输出异常。

需要添加以下配置，将IncludeException转为true：

"Logging": 
  "Region": "us-east-1",
  "LogGroup": "AspNetCore.WebSample",
  "IncludeLogLevel": true,
  "IncludeCategory": true,
  "IncludeNewline": true,
  "IncludeException": true,
  "IncludeEventId": false,
  "IncludeScopes": false,
  "LogLevel": 
    "Default": "Debug",
    "System": "Information",
    "Microsoft": "Information"
  

【参考方案1】：

这可能与您的日志格式化程序的配置方式有关。 MassTransit 使用容器中的ILoggerFactory。

例如我刚刚运行的测试出现异常显示消息，包括调用堆栈：

20:20:36.813-E R-FAULT loopback://localhost/mediator dc3a0000-ebb8-e450-78f0-08d9aa3a01fb MassTransit.TestFramework.Messages.PingMessage MassTransit.MessageHandler<MassTransit.TestFramework.Messages.PingMessage>(00:00:00.0006972)

MassTransit.TestFramework.IntentionalTestException: No thank you!

感谢您的回复，提示将我转发给答案，它是 aws-logging-dotnet 记录器，它默认配置为忽略日志输出中的异常！
