SpringOne Essentials is going to be amazing, but before we get there, and learn about all the big things in the Spring ecosystem for the last year, let's look at all the big things in the last week, with this week's recap!

• Spring Boot 2.7.8 available now
• Spring Boot 3.0.2 available now
• Spring Modulith 0.3 released
• A Bootiful Podcast: Dr. Amanda Martin, Gradle developer advocate
• Adventures in Maven Dependency Conflict Resolution

…

Hot on the heels of Spring Boot 3.0.2, I am excited to announce the 0.3 release of Spring Modulith. The release is packed with improvements. We have tweaked a couple of things that might require your attention and a couple of adapting changes to your code. The most notable changes are:

• GH-114 – We renamed the ….modulith.model package to ….modulith.core. This primarily affects ApplicationModules. Please adapt your imports accordingly.

• GH-120 – The documentation support now generates diagram files using the *.puml file extension, as suggested by PlantUML. Please adapt your imports accordingly.

• GH-103 – ApplicationModuleInitializer implementations will be triggered upon application startup, in the order following the application module dependency structure (more core ones are invoked first). Also, ApplicationModules exposes a ….getComparator() to order Spring beans that way. Note, that this requires the JGraphT library to be on the classpath (automatically pulled in via the spring-modulith-runtime artifact). See the reference documentation for details.

Spring Cloud Gateway 4.0 is finally here! Thanks to our community contributions we have introduced new features and interesting filters.

This blog post details new noteworthy and explains some of the new filters included, how they work and how you can use it to provide more insights into your applications.

First of all, let's talk about cache! Cache is a complicated issue and that's why we have introduced two new filters related to it, but take into account that these filters can make the gateway memory constrained so use them carefully.

CacheRequestBody

Manipulating the request body can cause issues if not done properly, so we made it easy for you; with this filter we offer the possibility to cache the request body before it to the downstream and get that body from an exchange attribute. It will be available in the ServerWebExchange.getAttributes() under a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR…

Hi, Spring fans! Welcome to another installment of This Week in Spring! I went to Helsinki, Finland, last week, and this week I'm in Atlanta, Georgia, to speak at the Atlanta Java User Group. And, of course, next week, I'll be in New York to join a viewing party for the airing of SpringOne Essentials. You're going to join us, I trust? It's going to be awesome!

Look, it's Tuesday. Tuesdays are no fun. We're three solid days away from fun winter ski slopes from Friday. But that's OK because every day is a chance to learn. And this week's no exception: we've got a ton to look at it, so let's…

New releases of Spring Boot are being released on a quite frequent schedule and updating your projects to newer versions of Spring Boot is something that many teams and organizations around the globe do as part of their daily work.

Sometimes those upgrades are simple and easy, for example for new patch releases that mostly include changes to fix bugs and address CVEs. In contrast to that, upgrading to a new minor or even a new major version requires more work, including code changes to adapt to new or changed APIs, updating configurations to not use deprecated keys anymore, and more.

Each new minor or major version of Spring therefore ships with a comprehensive guide and documentation about those changes and you can read and follow to upgrade your project. A good example of this is the new migration guide for upgrading your projects to Spring Boot 3…

On behalf of the team, I’m pleased to announce the availability of the 2022.0.1 and 2021.2.7 service releases. Those releases ship with mostly bug fixes and dependency upgrades.

For your convenience, the next Spring Boot releases will pick up 2022.0.1 and 2021.2.7 in the upcoming days. To round things off, here are the links to the individual modules, changelogs, and documentation:
