Docker Compose support in Spring Boot 3.1 builds on top of the ConnectionDetails abstraction, which we've featured in a separate blog post. If you haven't already read it, please do so before reading this post.

Docker Compose "is a tool for defining and running multi-container Docker applications". A Docker Compose configuration file, usually named docker-compose.yaml or compose.yaml, allows you to define services. Such services must have a name and a Docker image. Optionally you can also define environment variables, exposed ports, labels, how services relate to one another, and so on.

Hi, Spring fans! Welcome to another installment of This Week in Spring! I'm in Sydney, Australia, talking to customers, koalas, kangaroos, and whoever else will listen! I'll be doing a live presentation, tonight at the Microsoft Reactor here in Sydney. Register now and come join me!

As usual, we've got a ton of stuff to get through so let's dive right into it!

• On last week's installment of A Bootiful Podcast, I talked to Angular Google Developer Expert Santosh Yadav.
• I love this blog by our own Toshiaki Maki looking at how to implement polling-based outbox pattern with Spring Integration
• That blog, incidentally, was inspired by a blog written by Spring Integration lead Artem Bilan whose source code you can find here: artembilan/microservices-patterns-spring-integration: Spring Integration implementations for well-known Microservices Patterns
• A deeper-dive into Spring Boot 3.1's ConnectionDetails abstraction
• Spring Tools 4.19.0 released
• …

If you've used Spring Boot for a while, you're probably familiar with setting up connection details using properties. For example, you may have used spring.datasource.url to configure a JDBC connection. In Spring Boot 3.1 this continues to work as you'd expect, but we've changed things a bit under the hood to decouple the auto-configurations from the properties.

There's now a new ConnectionDetails abstraction. This interface models the concept of a connection to a remote service. If you take a look at this interface, you'll see that it's empty. It serves as a tagging interface, and is extended by multiple other interfaces which model the connection to a concrete remote service, e.g. RedisConnectionDetails for connections to a Redis server or JdbcConnectionDetails…

Hi, Spring fans! In this (relatively quick) installment, recorded live from the lovely Spring I/O 2023, Josh Long talks to Microsoft's Sean Li about some of the latest and greatest in the Azure ecosystem for Spring developers.

Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are key components of securing communications between systems in a layered or service-oriented architecture. Spring Boot applications in such an architecture often accept incoming network connections or create outgoing connections, and developers are tasked with configuring applications to work in such a secure environment.

If you've ever worked with the Java security and SSL APIs, you're probably aware that this is not a particularly fun task. It often involves multiple trips to stackoverflow.com to copy and paste code. There are a…

Hi, Spring fans! Welcome to another installment of This Week in Spring! And what an insane week it's been! Long story short, I've spent 10-12 hours a day over the last five days migrating a dozen differnet applications and services from one GKE cluster to another, taking the time to update things as much as possible. In the case of at least one Vue.js application, this meant some major reworking of the codebase. It's also meant rewriting lots of Github Actions with the new best-practices and patterns, which I confess has been painful.

Once everything's fully migrated (soon, I hope!), I think a…
