TraceId missing using log4j2 logger with jaeger exporter

My basic framework lib versions:

traceId and spanId logging well in config: spring.sleuth.exporter.otlp.enabled: true and spring.sleuth.exporter.jaeger.enabled: false, but didnt working with the jaeger exporter configed only. i tried to set my log4j2.xml patterns with %X{X-B3-TraceId} or %X{traceId} , still not logging traceId out, is there any config i missed to config?

Resolved by exclude redundant logging lib dependencies,just keep only one logging tool for working
