Hi, Spring fans! In this installment Josh Long talks to Spring contributor and adjunct professor at Mines Paris, Daniel Garnier-Moiroux (@kehrlann), about the wild and wonderful intersection of all things Spring Security and Kubernetes, productized Spring Cloud Services, and more, recorded live at SpringOne 2023 from Las Vegas, Nevada!

TL;DR:

Starting with Spring Data JDBC 3.2.0-M2, Spring Data JDBC supports Single Query Loading. Single Query Loading loads arbitrary aggregates with a single select statement.

To enable Single Query Loading you need to call setSingleQueryLoadingEnabled(true) on your RelationalMappingContext.

In 3.2.0-M2, this works only for simple aggregates, consisting of an aggregate root and a single collection of other entities. It is also limited to the findAll, findById, and findAllByIds methods in CrudRepository. Future versions will improve on that. A final limitation is that the database you use has to support analytic functions (AKA window functions). All the officially supported databases except…

Hi, Spring fans! Welcome to another installment of This Week in Spring! I'm exhausted. Seriously. Last week was mental. If you need me, I'll be over sipping on a tea...

But, before that, there's a ton of things to cover from this last week, as always, and there's no rest for the curious, so let's get that out of the way first, shall we?

• I did a (personal) recap of my experience at SpringOne 2023, our annual tentpole event that we held coincadent with VMWare Explore 2023 in sunny Las Vegas, NV. If you were there, you know, if you weren't, well, read on...!
• Our friend Siva has a great blog looking at the new JdbcClient in Spring Framework 6.1
• I just realized that Spring Cloud Alibaba has a fancy landing page!
• A Bootiful Podcast: cloud native Chris Richardson
• From Buzz to Brilliance: Spring Kafka Unleashed for Asynchronous Microservices Magic

Hi, Spring fans! Look, it's Monday after the first in-person SpringOne of the 2020s and the first since the pandemic, and, being honest, I'm bushed! Vegas is a dizzying, sensational, overwhelming, exciting experience, and SpringOne is too. But it was worth it. The SpringOne show surpassed all expectations, so it was definitely worth it.

This overwhelming scale was nowhere more evident than in the keynote, which was standing room only. I can't really recap the entire show, but I do want to talk about some of the huge themes you'd have seen addressed in the keynote.

During the keynote, the good…

This is the fifth article of a series about how to tackle various challenges you might encounter when using Spring Data JDBC. The series consists of:

1. Spring Data JDBC - How to use custom ID generation?

2. Spring Data JDBC - How do I make bidirectional relationships?.

3. Spring Data JDBC - How do I implement caching?

4. Spring Data JDBC - How Can I Do a Partial Update of an Aggregate Root?

5. Spring Data JDBC - How do I Generate the Schema for my Domain Model? (This article)

If you are new to Spring Data JDBC, you should start by reading its introduction and this article, which explains the relevance of aggregates in the context of Spring Data JDBC…

Hi, Spring fans! In this installment, Josh Long (@starbuxman) talks to original cloud native Chris Richardson on microservices, architecture, and more.

Hi, Spring fans! Welcome to another installment of This Week in Spring! And, would you believe it, I'm writing this at SpringOne 2023, in sunny Las Vegas, Nevada. This is the first in-person SpringOne since 2019, and I'm so, so, so glad to be here!

We've got a ton of things to get into this week, let's dive right into it!

• This year we're celebrating twenty (20!) years since the early builds of Spring Framework 1.0, and ten (10!!) years since the early builds of Spring Boot 1.0. Did you see this amazing easter-egg, The History of Spring?? It's amazing!
• We announced a new project called Spring AI that provides a convenient abstraction to allow developers to work with Large Language Models like Azure OpenAI and regular OpenAI, and - hopefully - more in the future. I did a live stream with its founder, Dr. Mark Pollack, here, and we did a demo you can look at here
• Spring Authorization Server 1.1.2 available now
• …

In Spring Security 5, we saw many developments in the OAuth2 story with the introduction of OAuth2 Resource Server and OAuth2 Client into the framework.

Today, it is quite convenient to develop applications that are secured by OAuth2 using the features available in OAuth2 Resource Server. Additionally, we can take advantage OAuth2 Client features to integrate with OAuth 2.0 and OpenID Connect 1.0 providers, making it possible to authenticate users with OAuth2 Login and/or make protected requests to applications secured by OAuth2.

However, the OAuth2 landscape is very complex, and customization…
