Hi, Spring fans! Welcome to another extra-meaty installment of This Week in Spring! This week, we’ve got a ton of stuff to look at so I won’t belabor it!

• Tomorrow, the 1st of April, marks the 6 year anniversary of Spring Boot 1.0 going GA! Happy birthday my old friend!
• Spring Data Neumann goes RC1
• Spring Boot for Apache Geode & Pivotal GemFire 1.2.6.RELEASE Available
• @DynamicPropertySource in Spring Framework 5.2.5 and Spring Boot 2.2.6
• In last week’s episode of A Bootiful Podcast, I talk to Apache Groovy, Testcontainers, and Reactor committer Sergei Egorov
• Spring Boot 2.2.6 available now
• Liveness and Readiness Probes with Spring Boot
• Spring Data Moore SR6 available now
• In last week’s installment of Spring Tips, I look at Spring Cloud Loadbalancer
• Microsoft’s Julien Dubois has published a nice how-to article that covers all corners of a new Gradle plugin to deploy Spring-powered Azure Functions

• Do not miss the much-requested second installment to Ryan Baxter’s look at Spring on Kubernetes - register now!
• Inside the VMware Open Source Program Office
• I love this article introducing utility classes in the JDK
• Last week’s #TGIK8s with Tanzu’s Joe Beda is definitely worth a listen. It looks at Cloud Events and Argo
• How to use Spring Data R2DBC with Azure Database for MySQL
• Good news from Spring Data lead Mark Paluch on Twitter: SpringData R2DBC now supports query derivation thanks to an amazing contribution by Роман Чигвинцев
• This is a cool Spring Boot Tutorial on Building Microservices Deployed to Google Cloud
• Here is how Eric Satterwhite turned PostgreSQL into a real time data hub with RabbitMQ and about 80 lines of SQL
• I love this episode of TGIR (Thank Goodness It’s RabbitMQ!) on how to contribute to RabbitMQ
• The Spring Boot team snuck a new feature, @​DynamicPropertySource, into Spring Framework 5.2.5 (and therefore Spring Boot 2.2.6)
• We’ve added Mutation Testing integration to our @springcloud projects! Check this out…
• The new Kotlin 1.4-M1 release looks awesome
• This an interesting post by Igor Manushin on making routing in Spring even faster in English. Here, I am pretty sure, is the Russian version of the same article

• Did you know that Spring Boot 2.2.6 and 2.3.x (milestones) have #AllTestsGreenOnJDK14 ? Go to the Spring Initializr and you’ll be able to try it all out right now!

• Also, did you see the spiffy new makeover for my second favorite place on the internet, after production, start.Spring.io?
• See Logging with Spring Boot at Elastic Community Events EMEA Virtual
• A very important update for all of our Spring Data MongoDB users: Annotation based index creation is now turned OFF by default and needs to be enabled eg. when relying on @GeoSpatialIndexed
• An Introduction to Spring Projects

I’m pleased to announce that Spring Data Neumann has entered the release candidate phase with 86 tickets fixed. This release is the first of two release candidates. This release candidate ships with a series of noteworthy changes:

• Upgrade to Couchbase SDK 3.
• Spring Data MongoDB no longer automatically creates indexes from @Indexed annotations by default.
• The Cassandra module supports configurable naming strategies and ships with a revised data type resolution mechanism.
• Spring Data Elasticsearch now supports auditing and entity callbacks.
• Support for query derivation in Spring Data R2DBC.
• Dialect discovery for Spring Data JDBC, supporting H2, HSQLDB, Postgres, MariaDB, MySQL, and SQL Server.
• Upgrade to Querydsl 4.3.
• Ready for JDK 14.

Recently, when talking about testing Spring Boot applications at Spring IO and SpringOne Platform, I’ve mentioned Testcontainers and discussed the boilerplate involved in configuring your tests to use the service running inside the container. I’m delighted to say that, with the recent Spring Framework 5.2.5 release, that boilerplate is no more.

Prior to the changes that we’ve just released, your integration test would look similar to the following:

@SpringBootTest
@Testcontainers
@ContextConfiguration(initializers = ExampleIntegrationTests.Initializer.class)
class ExampleIntegrationTests {

    @Container
    static Neo4jContainer<?> neo4j = new Neo4jContainer<>();

    static class Initializer implements
            ApplicationContextInitializer<ConfigurableApplicationContext> {

        @Override
        public void initialize(ConfigurableApplicationContext context) {
            TestPropertyValues.of("spring.data.neo4j.uri=" + neo4j.getBoltUrl())
                    .applyTo(context.getEnvironment());
        }

    }

}

Hi, Spring fans! Welcome to another installment of Spring Tips! In this installment, we’re going to look at a new feature in Spring Cloud, Spring Cloud Loadbalancer. Spring Cloud Loadbalancer is a generic abstraction that can do the work that we used to do with Netflix’s Ribbon project. Spring Cloud still supports Netflix Ribbon, but Netflix Ribbons days are numbered, like so much else of the Netflix microservices stack, so we’ve provided an abstraction to support an alternative.
