Spring Download 2.0 Prometheus Backward Compatibility

Question

I am migrating to Spring Boot 2.0 and am having problems with my Prometheus tags.

I know that MicroMeter is a new way of doing things that are not as crisp as the Prometheus libraries, but OK.

My problem is that if I do not want to change my indicators now, I can not switch to Spring Boot 2.0. I'm right?

I tried the following:

Trial No. 1

• Keep my implementations "as is"
• add a new dependency io.micrometer:micrometer-registry-prometheus:1.0.2to my application (the actuator is already there)
• change the material in application.propertiesto access the endpointactuator/prometheus

=> My Countersand Gaugesfrom the past ignored. Well, I understand this from a technical point of view.

Trial No. 2

• Keep my implementations "as is"
• "" 'io.prometheus .
• application.properties, actuator/prometheus

= > excpetion
