Learn Spring Boot 2 by Building a Microservice in a Hyperfocused Way

Your fastest and easiest way to get started. No fluff, no bullshit, no outdated tutorials and other things wasting your time. Code-centric and to the point explanations.

Together we will write a production-ready microservice with a REST API in just a few hours. You don’t even have to have any prior experience with the Spring Framework at all. You will learn it on the go.

Why should I learn Spring Boot and not Node.js, Laravel or any other?

Spring and Spring Boot are a mature technolgy enlighting the Java dev world for over 15 years now. It is the alternative to Java Enterprise. Enterprise-proven and still lightweight.

Ever compared the salaries of Spring Developers vs Javascript or PHP? Way more money on the Spring side.

Should I start with Spring or Spring Boot?

It is easier learning Spring by starting out with Spring Boot because, in its essence, Spring Boot is just a way of rapidly starting new Spring applications with a few bells and whistles added of course. It hides away an enormous amount of the complexity involved and thus makes it way more accessible for beginners to have their first successes soon as reader Benoit experienced first hand.

I hesitated first to learn Spring Boot instead of Spring standalone. Glad I did anyway. Learned a good and easy way to develop an application with rest services and it even covered deployment. Now, I’m having other choices and know how to run a Spring app from scratch. Clearly, recommend it for beginners as it was easy to learn.


Who am I and why should you listen?

My name is Jens and I am a software developer from Frankfurt, Germany. Self-taught and professionally coding since 1999 in the Java universe. I started with Java 1.1 and enjoyed the pain of Java Enterprise - yeah EJB Spec 0.93b - that was awful. Spring saved me, so I switched to it over a decade ago and never looked back.

Some time ago I discovered that my purpose in life is helping others in making better decisions for themselves which they can actually live with. Instead of doing this on the go, I switched now full-time to teaching fellow devs.

My guides are the kind of material I love reading myself but never found before.

Why buy your Guide?

I am honest with you. You have multiple options to get started with Spring Boot. My guide is not the only one. Although, it is the fastest and without the pitfalls of the alternatives. But let’s take a closer look at your alternatives and how they compare:

Using Free Online Tutorials

Going full DIY using the Spring Boot docs and maybe some free incomplete, outdated and confusing tutorials online; most are for version 1.5 or earlier. It works but takes lots of time and frustration, except you are like me and have been already working with Spring for a decade; then it is not more as a bump on the road… However, it probably will take you a few weeks or even months to understand how to build an application.

Using Traditional Programming Books

You could use a traditional programming book, one of those 400+ page gorilla compendiums where they show you almost all features of Spring Boot but leave you clueless how to use those bits and implement even a simple application. At the same time you are making one of the biggest learning mistakes and reading the book front to back. Nothing will stick. How do I know? I made the same mistake before like many others too. They are reference material, but not for actively learning anything. How long does it take you to read such a work? 1 month? 2 month? Even more? Have you built anything in that time?

Using Video Courses

Or you go the “modern” way and binge watch a few video courses averaging at a 10 hours play time. Not included are the endless pause, rewind, play cycles. Or fast forwarding because the voice of the instructor is so annoying or what he says is too redundant. As much as I love videos as the next guy, it is the wrong media for learning hard coding topics.

In-Class Training

Honestly, it is the best option to attend on eof my in-person, in-class teachings here in Frankfurt. 2 to 3 days full-time deep dive into starting with Spring Boot and I as your instructor at your side guiding you. But that’s 1100 Euro for two days and there is a high chance you are not even close to my location.

Which leads me to the next best option.

Using my Pocket Guide with Hyperfocused Learning

I strongly believe that the best way to learn a new language or framework is to actually code in it and following a simple learning process. Mine looks in summary like:

Learning = ( Small scope, research and a structured way to actually build something ) * repeat * reason

The reason is up to you, but the rest of the equation is covered by my guide.

I did the research for you, I set the scope for building your first microservice with Spring Boot, and I deliver the structure too. In text form, without fluff or bullshit, so you can progress at your own pace and also search the material. Ever tried searching in a video?

Furthermore, you can write me and ask questions. I’ll help out.

I build it the way friends and I love learning and wish we could find when diving into new topics. Luckily, you can now and benefit from it.

Who is this not right for

The guide is not for you if you have never developed in Java or your most advanced application is Hello World.

The Project

We create a Microservice for storing comments and providing a REST-like Interface for interacting with the data. The sample application is modeled after a real production application to guide you through building your first Spring Boot application.

We focus on the backend and API and will not cover a UI.

You will also get these awesome bonuses

  • Your time - you save hours with this guide PRICELESS Value
  • Full source code of the final application $50 Value
  • Deluxe support per email (<48h response time, usually faster) (new) $500 Value
  • A bonus chapter implementing the backend with MongoDB with full source code (new) $15 Value
  • A cheat sheet covering Spring Boot Essentials $10 Value
  • A cheat sheet covering the fundamentals of Spring Data JPA $10 Value
  • A cheat sheet covering the essentials of Spring Data MongoDB $10 Value

Total value of the DELXUE edition is over 600 dollar and that’s not even counting your time.

  • Your saved time and headaches

Let’s assume you took the video route. It’s a 99 bucks video course which takes on average 10 hours of your time watching it. If your hour is worth 50$ then you actually pay 599$ (10h * 50$ + $99 course price) in total and haven’t even build your microservice yet.

With my guide you will probably be finished in under 5 hours and already have built the microservice at least once. You can do the math. And let’s not forget all headaches you will miss out.

Want to bang your head on the table and cry in agony, please use an alternative and don’t buy my guide. This guide is only for devs valuing their time and mental health.

But don’t take my word for it

I love this book. Just enough info to quickly get to the heart of the matter. I was new to Spring Boot and this book helped give me perspective. Thank you for writing it.

I bought this book because i wanted to learn a simple way of creating API endpoints AND securing them and I was happy to see that this book delivered. Most of the material I’ve read on this before was either too complex, outdated or simply skipped the security part entirely…


… This book … is much easier and fit for someone like me who is just starting out. It’s structured and the author clearly is an expert in the material…

Are there any restrictions on the pocket guides?
No. I trust you to do the right thing. They are 100% DRM free.

Do I need any prior knowledge or experience to learn Spring Boot
You need to be able to code in Java. Experience with the Spring Framework is not necessary. We will start with an introduction to the Spring Core, the basics, and then move forward to Spring Boot. As a build tool, we are using Maven, and we also cover it with a brief introduction in case you are not familiar with it.

I have another question.
No problem! Send me an email at info@codeboje.de
