无法观察TraceId

Question

我试图运行Spring Cloud Sleuth并观察traceid，spantid oin日志。

我的配置如下，但当我调用requesti cnat时，会在日志中看到任何traceId或logId。

有人帮忙吗。谢谢

如果我需要猜测，这是由您的一些定制Log4J设置引起的，更准确地说是您的Log4J模式（我没有看到它们，所以我只是猜测）。Spring Cloud Sleuth依赖于由Spring开箱即用启动设置的日志模式（请参阅：logging config）。

我建议您尝试一下，首先使用默认配置，如果有效，您可以自定义默认模式（我不建议自定义它，默认值很好）。
