MetricBeat with SpringBoot3 projects

[patpatpat123]

Hello Philip,

First of all, I wanted to say big thanks for this project.

It is very easy to read, and I learned a lot in the process.

Wanted to reach out because:

We are now in 2023, with SpringBoot 3 available, with a direct integration with Micrometer for metrics.

Elastic also evolved a lot. I was wondering if you could share an example of a SpringBoot 3 application generating metrics, and having MetricBeat scrapping/polling the metrics from it please?

This would put this repo back in the game and can improve overall technical expertise on SpringBoot and beat.

Thank you
