It’s not uncommon for a software engineer to find themself blocked. The reasons might vary: it could be a high uncertainty, when it’s unclear how exactly to implement the feature; or it could be a tech decision to take having multiple options with their own pros and cons. With this article I want to share the way I take decisions in such cases and how it might help you to unblock yourself.

It was all nice & fun adding domain-specific metrics to the dashboard until I realized that I can’t find any values for Spring Boot system metrics like CPU usage or memory usage. What happened to them? Who stole my system metrics?! Let’s find out.

I believe that the decorator pattern is one of the most powerful design patterns out there. It is the rule “composition > inheritance” at it’s best: it makes your classes easily testable, it allows to decompose huge classes into smaller ones, and it makes your code reusable and modular. In fact, Spring Framework relies heavily on this pattern. Unfortunately, I think that Spring doesn’t provide a really convenient way to configure decorators with it. This is the second part of how to customize dependency injection in Spring, and today we’re going to see how to make Spring’s DI respect decorators.

I work with Spring Framework a lot. I can’t even remember a single project I had at work where I didn’t use it.

This article is a result of me trying to customize dependency injection in Spring to make it smarter as well as trying to get a deeper understanding of how does it work. I hope you’ll find it useful as well!
