Introduction

This is a guest blog post by Gerrit Meier from Neo4j who maintain(s) the Spring Data Neo4j module.

A few weeks ago version 1.2.0 of Spring (for) GraphQL was released with a bunch of new features. This also includes even better integration with Spring Data modules. Motivated by those changes, more support in Spring Data Neo4j has been added, to give the best experience when using it in combination with Spring GraphQL. This post will guide you on creating a Spring application with data stored in Neo4j and GraphQL support. If you are only partial interested in the domain, you can…

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I am in Seoul talking to developers about the latest-and-greatest in Spring Boot 3! There's so much great stuff coming, and so much great stuff already. There are a few things I'm super excited about.

First, yesterday I did a joint presentation with my friend the one the only the amazing Trustin Lee, creator of Netty and lead of the Armeria Project over at LINE corporation. LINE is a super popular social messaging application used a lot in Korea and in Japan. It was a ton of fun collaborating with, and copresenting with, him…

There's been support for Testcontainers in Spring Boot for some time now, and Spring Boot 3.1 improves it further. But first, let's take a look at what Testcontainers is and how it's usually used.

Testcontainers is an open source framework for providing throwaway, lightweight instances of databases, message brokers, web browsers, or just about anything that can run in a Docker container.

If you have used Testcontainers in the past, there's a high chance that you have been using them in integration tests:

@SpringBootTest
@Testcontainers
class MyIntegrationTests {

    @Container
    static…

Hi, Spring fans! In this installment, Josh Long talks to Micrometer lead Tommy Ludwig, recorded from beautiful Barcelona, Spain during the fabulous Spring I/O event!

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…
