How to enrich Jaeger opentracing data with the application logs (produced by slf4j) for Spring Boot?

https://github.com/opentracing-contrib/java-spring-cloud project automatically sends standard logging to the active span. Just add the following dependency to your pom.xml

<dependency>
   <groupId>io.opentracing.contrib</groupId>
   <artifactId>opentracing-spring-cloud-starter</artifactId>
</dependency>

Or use this https://github.com/opentracing-contrib/java-spring-cloud/tree/master/instrument-starters/opentracing-spring-cloud-core starter if you want only logging integration.
