Part of our Java team visited the 10th edition of the Spring Developer Conference in Barcelona. They immersed themselves in the world of Java development and explored the latest trends, innovations, and best practices. From groundbreaking technologies to industry insights, the conference promised to be an unforgettable experience. But was it really? Read on to find out if it was worth the visit directly from our colleague, Mario Petrovski.

How satisfied were you with the event and how useful was the event?

I was pleasantly surprised by the excellent organization of the event. It featured top-notch speakers, a beautiful venue, and much much more. The event was truly amazing, and I learned a lot of new things. Furthermore, most of the speakers were actively involved in the development of the Spring Framework, which is not only the most advanced but also the most widely used framework in the Java ecosystem.

What was your favorite experience or moment of the event?

My favorite experience was meeting and listening to Josh Long. As someone actively involved in the development of the Spring Framework, he delivered an amazing presentation on Spring Boot 3. After watching countless videos of him, I finally had the chance to meet him in person and listen to his insights firsthand.

What was your biggest takeaway from the event and what did you learn at the event?

There were numerous technical insights that I gained during the conference. Here are a few noteworthy ones:

  • Project CRaC: This project focuses on improving the startup time of Java applications, addressing a well-known issue in the Java ecosystem. It significantly enhances the startup time, making it a valuable resource for optimizing Java application performance. I highly recommend checking it out if you’re seeking to optimize your Java application’s startup time.
  • Virtual Threads (Project Loom): This upcoming feature is set to revolutionize the Java ecosystem. Virtual Threads will be introduced in Java 21, scheduled for release on August 10, 2023. Anticipated to bring substantial performance improvements, I’m eagerly looking forward to its impact on Java development.
  • Contributing to Spring Framework: One standout session discussed contributing to the Spring Framework. As an open-source project, Spring welcomes contributions from developers worldwide. This session provided valuable insights into how we can start contributing to the project. Inspired by this, I am planning to contribute to the Spring Project as soon as I find some free time.

The conference provided a wealth of technical knowledge and inspired me to explore new avenues for optimizing Java applications and actively contributing to the Spring Framework.

Would you like to attend this event again in the future?

Of course, if I have the opportunity to attend again, I will definitely go. Overall, the conference was amazing, providing ample opportunities to learn and connect with developers from around the world who are using the same technology to solve business problems. Additionally, Barcelona is a fantastic city, offering plenty to do and explore after the conference concludes.
