> Can you describe the features of Springboot that you find valuable when developing a microservice?

You never did.

Instead you claimed that "Java has well-understood and popular ecosystem" and complained about "not having the luxury of time"

Hence we should have the luxury of time to understand your original ecosystem and guess what you probably might need?

I'm afraid this attitude won't help your cause.

But I'm happy for you to already have found a solution in the Java world. :)
