demo中的traceid无法打印

最近看文档的[2.0.1 新特性介绍： 在日志中记录trace id](https://servicecomb.incubator.apache.org/references/java-chassis/zh_CN/featured-topics/features/trace-id.html)，我按照文档里的说明配置了一下，发现实际traceid存在，但是最终日志/console不会打印。
刚才运行[servicecomb-java-chassis/demo/demo-jaxrs](https://github.com/apache/servicecomb-java-chassis/tree/master/demo/demo-jaxrs)看了下，发现traceid也是存在的，但是日志没有打印，请问是还需要别的配置吗？
比如：
```log
[2023-08-11 09:59:36,128][transport-vert.x-eventloop-thread-0][ERROR][org.apache.servicecomb.core.exception.DefaultExceptionProcessor:158][] failed to invoke jaxrs.MultiErrorCodeService.errorCodeWithHeader, endpoint=rest://192.168.56.1:8080, trace id=64d5960891532378.
```
最后一个`[]`按配置是`[%X{SERVICECOMB_TRACE_ID}]`

Start by reproducing the issue in demo/demo-jaxrs and compare its behavior with the trace-id documentation linked in the report. Check how the configured [%X{SERVICECOMB_TRACE_ID}] value is expected to reach the console log; done means the existing trace ID appears in the final log output.
