在我将我的应用程序从spring Boot 2.7迁移到3.1.5之后，我无法将traceId和spanId记录到logger。
我将sleuth迁移到micromerter，如迁移指南中所述，并将log4j2.xml文件编辑为推荐的格式[%X{traceId:-}, %X{spanId:-}]，但它没有记录，如您所见：

2023-11-01 16:38:15.854+0100 [level=INFO ][,]  INFO MBP-14 --- [ctor-http-nio-3] com.example.demo.Controller : Hello, World!

我用分支 2.7 和 3.1 准备了repo here，可以通过调用 hello 端点来复制它。
