if spring boot service have servlet.contextPath and managed by eureka, how to config it in prometheus.yml?

If you want to explicitly set the base path for all services with the sd mechanism, you can just hardcode it in prometheus.yml like so: metrics_path: /mybasepath/actuator/prometheus.

If you have a different base path for each service, you need to send the base path along with the eureka discovery registration (see https://projects.spring.io/spring-cloud/spring-cloud.html#_eureka_metadata_for_instances_and_clients). As soon as it is available in eureka, prometheus will get this metadata (as something like __meta_consulmetadata...). Based on this, you can use the relabeling feature of prometheus to set the correct metrics path for the service (see https://prometheus.io/docs/prometheus/latest/configuration/configuration/#relabel_config).
