Spring Blog

On behalf of the team and all contributors, I am pleased to announce that Spring Batch 5.0.0-M7 is now available from our milestone repository.

The main theme of this milestone is the improvement of job parameters handling in Spring Batch. Two main changes were introduced in this release:

• Add support to use any type as a job parameter
• Improve job parameters conversion

This blog post walks through these two major changes in details. For the complete list of changes, please check the release notes.

Add support to use any type as a job parameter

Hi, Spring fans! Welcome to another installment of This Week in Spring! It’s October 4th, 2022, and I’m in Austin, TX, for the new version of show formerly known as the Kafka Summit, here to talk to folks about the amazing opportunities for Spring Boot and Apache Kafka. On the 12th, I’ll be in Antwerp, Belgium, for the amazing Devoxx show. On October 17-20th, I’ll be in Las Vegas, for the new version of JavaOne. And, well, there’s more but I can’t say exactly. Stay tuned!

And as for now, well, I’m excited to be here! We’ve got a ton of cool stuff to cover this week, so let’s dive right into it!

Hi, Spring fans! In this installment, Josh Long (@starbuxman) talks to his friend Chris Richardson (@crichardson), who helped articulate and advance cloud computing, reactive programming, microservices, domain-driven design, event sourcing, and so much more years before the zeitgeist. Also, we used to work together!

Want to meet more amazing people in our ecosystem, like Chris? SpringOne 2022 is almost here! I feel like it’s that anxious, exciting time before, sort of important holiday where you get given gifts! And with it, Spring Boot 3 and Spring Framework 6. We’re going to be announcing everything right here on the Spring blog, of course, but if you want a chance to learn from the source, then I hope you’ll join us 6-8 December 2022, right here in my hometown of San Francisco, my favorite west coast city in the USA, and my hometown. (Psst.: If you register now, there’s a $200 discount from the pass price with this code S1VM22_Advocate_200.)

Using username/password credentials to access one application from another presents a huge security risk for many reasons. Today, we are announcing the preview of passwordless connections for Java applications to Azure database and eventing services, letting you finally shift away from using passwords.

Security Challenges with Passwords

Passwords should be used with caution, and developers must never place passwords in an unsecure location. Many Java applications connect to backend data, cache, messaging, and eventing services using usernames and passwords, or other sensitive credentials such as access tokens or connection strings. If exposed, the passwords could be used to gain unauthorized access to sensitive information such as a sales catalog that you built for an upcoming campaign, or simply all customer data that must be private.

Hi, Spring fans! Welcome to another installment of This Week in Spring!

It’s the last week of September, already! The year’s more done than not. The days are receding into darkness earlier. And the Pumpkin Spice Lattes are upon us. The darker and colder days are kind of a bummer, but I’m stil excited and overjoyed this time of year. You know why?

SpringOne 2022 is almost here! I feel like it’s that anxious, exciting time before sort of important holiday where you get given gifts! And with it, Spring Boot 3 and Spring Framework 6. We’re going to be announcing everything right here on the Spring blog, of course, but if you want a chance to learn from the source, then I hope you’ll join us 6-8 December, 2022, right here in my hometown of San Francisco, my favorite west coast city in the USA, and my hometown. )Psst.: If you register now, there’s a $200 discount from the pass price with this code S1VM22_Advocate_200.)

The Spring Team has been working on native image support for Spring Applications for quite some time. After 3+ years of incubation in the Spring Native experimental project with Spring Boot 2, native support is moving to General Availability with Spring Framework 6 and Spring Boot 3!

Native images provide almost instant startup time and reduced memory consumption for Java applications. The recent Spring Boot 3.0.0-M5 release marks the first time we’re asking for broader community feedback on our native story. If you need to catch-up on the basics, please refer to the Ahead Of Time basics blog post from late March. You can also learn how to prepare your applications for Spring Boot 3.0.

It has taken me an embarrassingly long time to appreciate and understand that the devil is in the details regarding software development. Writing happy-path business logic isn’t the hard part! It’s the failure cases, observability, resilience, and process. It’s security and other so-called non-functional requirements. It’s architecting for agility. It’s production. Spring is unique because it sits at the crossroads of many exciting application development discussions.

Spring’s community contains multitudes and is one of the key defining features. This diversity of discussion means that any conference that endeavors to cover the full sweep of ideas has its work cut out. I don’t know of any other show - and I’ve spoken at many thousands of shows and events in my life! - that completely covers the different dimensions of application development like SpringOne does. I feel like SpringOne is the closest, anyway, and I want to talk about what I’m looking forward to about this year’s SpringOne 2022 event.

On behalf of the team and everyone who has contributed, I’m happy to announce that Spring Boot 3.0.0-M5 has been released and is now available from https://repo.spring.io/milestone.

This release includes 153 enhancements, documentation improvements, dependency upgrades, and bug fixes. Notable new features include:

• Improved Ahead-of-Time (AOT) processing and native image support
• Improved actuator endpoints sanitization
• Jersey support re-instated

Please see the release notes for more details and upgrade instructions.
