Yes it is possible, you can implement https://github.com/opentracing-contrib/java-web-servlet-filter/blob/master/opentracing-web-servlet-filter/src/main/java/io/opentracing/contrib/web/servlet/filter/ServletFilterSpanDecorator.java and supply it to tracing filter constructor or use standard filter and get the active span from the tracer or scope manager.
