Ratpack 中的 /buildinfo 和 /health API 请求

Question

I am building a micro-service using Ratpack. I have a basic understanding of how requests are routed using chaining in ratpack. But what I can't understand is how my server responds to the "/buildinfo" and "/health" requests when I haven't defined any handler for these.

I want to know how I can modify and send some data which I want to as a response to these requests.

Answer 1

It's an inbuilt feature.

Ratpack does provide the HealthCheck interface which you can implement and write your own handler and override the check method to return your desired response when you call /health. You will need to add your new handler to your registry.
