🔥 What’s new in Spring Boot 3.1
Happy Monday and welcome to the start of another work week. I hope you had a wonderful weekend. Mine was great - this past weekend I had my first daddy-daughter dance with my oldest daughter, Bella (5). It was an amazing night and she was so excited to get “fancied up”, as she says. We had a delicious meal with friends, an ice cream bar, hula hoops, and of course, we danced the night away.
This week, I want to talk to you about the newly released Spring Boot 3.1 RC1. Additionally, I will discuss what I worked on last week, which includes Spring Beans, Spring Security, and YouTube Shorts.
Spring Boot 3.1.0 RC 1
Spring Boot 3.1.0 RC 1 has just been released. If you want to learn more about it, you can check out the release notes. I will highlight some of the new features in this release.
- Testcontainers - I’m a big fan of using Testcontainers in my integration tests to provide a lightweight throwaway database or any other container that I need. In Spring Boot 3.1 it’s also possible to use them at development time.
- Docker Compose - A new module
spring-boot-docker-composeprovides integration with Docker Compose. When your app is starting up, the Docker Compose integration will look for a configuration file in the current working directory. No more starting your application only to see an error because you forgot to rundocker compose up. - SSL Configuration - SSL trust material such as Java KeyStores and PEM-encoded certificates can now be configured using properties and applied to connections of various types such as embedded web servers, data services,
RestTemplateandWebClientin a more consistent manner. - Docker Images - There are some nice improvements to customizing the Docker Image using Maven or Gradle.
- Dependency Upgrades - Spring Boot 3.1.0-RC1 moves to new versions of several Spring projects
We plan to discuss this topic in more depth during Spring Office Hours this week. Please join us live or watch the replay. I also plan to create one or two videos for my YouTube channel. If you haven't subscribed yet, what are you waiting for?
Content Creation Machine
Here are the highlights of the content I worked on last week.
Spring Beans
In a recent video, I discussed Spring Beans and how to create them using @Component vs @Bean annotations. Have you ever come across a term that seemed confusing, only to realize later that it was quite simple? For me, Spring Beans was one of those terms when I first started out. In this video, I delve deeper into the topic. I also covered Spring Beans in my Spring Boot Crash Course, but that is a four-hour long video.
Multiple Spring Security Configs
Recently, I have discussed how to configure Spring Security using the new component model. This video covers a couple of scenarios where you may need multiple security configurations and how to create them. In previous versions of Spring Security, this was difficult, but it is now much easier.
Shorts
I love making YouTube shorts because they allow me to produce videos in a shorter time cycle. They also provide an opportunity for me to try out new ideas and editing techniques. Last week, I produced a short video on how to pronounce "char" in Java, and it was so much fun. I was literally laughing out loud in between takes. Moreover, they have been receiving a good number of views, which is encouraging. So, be on the lookout for more videos this week!
Around the web
🎬 Videos
I really enjoyed this 60 Minutes piece on The AI revolution. Google's CEO, Sundar Pichai, believes AI's impact will depend on human nature and that the AI revolution is coming quickly.
👨🏼💻 Projects
As a huge fan of Vue and Nuxt, it was great to see the Nuxt team release another really impressive minor update. Check out this blog post to learn about the new features in Nuxt 3.4.
