Only modifying the pattern in the log configuration file can realize the injection of TraceID and SpanID. The log injection feature of OpenTelemetry enhanced Java probe supports the following logging frameworks:
Log4j 1.2+
Log4j2 2.7+
Logback 1.0+

Log4j2 supports multiple format configuration files, including XML, JSON, YAML, Properties, etc. Taking XML format as an example, there are multiple ways to write Pattern. Please refer to one of the existing ways:
