TLDR; I am happy to announce that I am starting the SpringBoot - The Missing Guide video series on my SivaLabs YouTube Channel. This SpringBoot - The Missing Guide video series is for those who need help understanding SpringBoot’s magic. In this series, I will explain the core concepts used in Spring and SpringBoot with practical examples. Also, I will give a deep-dive explanation of SpringBoot’s AutoConfiguration and how to customize the default configuration.

Few months ago I asked on Twitter “why you think Java is complex?” to understand others perspective. I'm really surprised looking at so many people assuming #Java is complex than other languages. I worked with mostly Java and in recent years I worked with Go, NodeJS too. But I feel Java is less complex and more productive. Any specific points why you think Java is complex? — Siva (@sivalabs) April 1, 2022 And, I got many responses(opinions, insights) and I compiled all the responses into this blog post My attempt to understand why people perceive Java as complex.

First of all, Wish you a very happy new year and I hope this year will bring more joy and happiness into your lives. I would like to share how was 2022 for me and what my plans are for 2023. Highlights of 2022 The year 2022 is very eventful for me and lots of interesting things happened. 1. “How to Become a Software Architect” series with in28minutes and JavaBrains I collaborated with in28minutes Ranga and JavaBrains Koushik and did a “How to Become a Software Architect” series

Spring Framework 6 implemented the Problem Details for HTTP APIs specification, RFC 7807. In this article we will learn how to handle exceptions in SpringBoot 3 REST API(which uses Spring Framework 6) and provide error responses using ProblemDetails API. We are going to reuse the SpringBoot 3 sample application spring-boot-jpa-crud-demo which we used for Using Java Records with Spring Boot 3 article. Assume we have the following REST API endpoints to create a bookmark and fetch a bookmark by id.

Records were introduced in Java 14 as a preview feature and became a standard feature with JDK 16. Records are a concise representation of immutable data class. Prior to Records this is how we usually create an immutable class. import java.util.Objects; class Person { private final Long id; private final String name; public Person(Long id, String name) { this.id = id; this.name = name; } public Long getId() { return this.

Social media is a double-edged sword. Depending on how you use it can be really be helpful or become a source of pressure and frustration. I don’t use Facebook and Instagram much, but I use Twitter and recently started using LinkedIn too. Twitter is my primary source of technical information. I follow many good people in Java Community. Twitter is a great platform to connect with those awesome people and I learn a lot from what they share.

I got a chance to review the upcoming Cloud Native Spring in Action book by Thomas Vitale and here my review of the book. TLDR: If you know the basics of SpringBoot and want to master the advanced concepts and also understand what “Cloud Native” means and how to build & deploy production grade SpringBoot applications on Kubernetes then this is the book you are looking for. Longer version: There are many books on SpringBoot that are aimed towards complete beginners to intermediate skilled developers.

We, software developers, have a great advantage when it comes to getting help from others. Irrespective of how much experience you have you will need help fromm others. And, there are plenty of good people out there willing to help you by means of answering on StackOverflow, writing blog posts, making video tutorials etc. They are taking their personal time to help strangers whom they may never meet in-person, kudos to all of them.

We, software developers, aspire to become better by learning new tools and techniques. In addition to that, I find listening to the experts and learning from their experiences is a great way to upskill ourselves. We may want to learn a new technology, or want to start our own start-up company or learn why some hyped technologies failed. Also, we may want to learn some behavioural aspects like how to be empathetic to others, be a better mentor to juniors etc.

TLDR; I am happy to announce that I am going to create “SpringBoot Tips Video Series” on my SivaLabs YouTube Channel. This “SpringBoot Tips Series” is to help people who are new to SpringBoot to learn how to use SpringBoot with a keen focus on understanding how it works behind the scenes. Longer version I have been working with SpringBoot for several years, and I have written couple of books on it too.
