Most Java Developers still are trapped working in Banks. These developers cannot simply stop writing bureaucratic code. If you already identified yourself, unfortunately, this post isn't for you, I'm so sorry, you're completely lost, but don't worry, I'm pretty sure there's a special place in heaven for people like you. On the other hand, there are a few Java developers who could escape the agony of writing "enterprise" Java code and started writing Kotlin, Scala or even a non JVM language. If you are a developer like this…

Okay then, this post is supposed to be very short, so, let's begin. We are going to build a simple crud app using Spring Boot, specifically Spring Boot Data Rest and use Kotlin (of course)…

I've been away for a while and I've been playing with Finatra, so, I decided to write this post because I really enjoyed using it. Lately I've been using Scala a lot in my personal projects and even for testing my Java applications (it is much better than using JUnit, believe me), so, I also tried a few scala web frameworks out and I found out that Finatra is the easiest one (at least for me).

Choosing the right tools to create microservices is not always that simple. First, there are a lot of microservices application types, so, you need to choose the right tool for the right job. Second, there are a lot of tools to help you build these applications. I’m going to show you another tool set to help you build your microservices applications: Undertow + CDI + JAX-RS, persisting in a MongoDB. This will probably meet all your needs when we talk about microservices. Actually, it is pretty simple: We just need to…
