Milestone 4 of Spring Boot 2.0 brings important changes to the security auto-configuration provided by Spring Boot.

Problem Statement

Until Spring Boot 1.x, the default auto-configuration secured all of the application endpoints using basic authentication. If actuator was on the classpath, there was a separate security configuration that applied to the actuator endpoints. The way these two auto-configurations would turn on and off was completely independent. Because of this, users wanting to provide custom security found themselves fighting ordering issues with WebSecurityConfigurerAdapters.

Additionally, for actuator endpoints, the effects of the management.security.enabled…

Dear Spring Community,

Spring Session MongoDB 2.0.0.M3 is released. It is based on:

• Spring Session 2.0.0.M4

• Spring Data Kay-RC3

• Reactor Bismuth-M4

• Spring Framework 5.0.0.RC4

In this release, several new features have been added to simplify using it with your Spring WebFlux application.

@EnableMongoWebSession
public class SpringWebFluxConfig {

}

All you must do is apply the @EnableMongoWebSession to any of your Spring configuration classes to activate session support with MongoDB. Additionally, you must provide a ReactorMongoOperations Spring bean, but if you’re using Spring Boot’s spring-boot-starter-data-mongodb-reactive…

Hi Spring fans! This week I'm in Singapore for the amazing YOW! Singapore event and talking to customers.

Also, I'll be doing a meetup on testing - don't miss it!

• It's almost time for Spring 5! Spring Framework lead Juergen Hoeller just announced Spring Framework 5.0.RC4, which is aligned with Spring Boot 2.0.M4, JUnit 5, and Reactor 3.1 RC1. This might be your last chance to kick the tires before the big release! There's so much new stuff in this release!
• This is pretty interesting! There's a Spring Cloud Config Server MongoDB project in the Spring Cloud incubator. Try it out!
• Spring framework ninja Stéphane Nicoll just announced Spring Framework 4.3.11.
• Spring Cloud and Spring Data ninja Mark Paluch just announced Spring Cloud Vault 1.1.0.RC1. This release includes pull-mode support for AppRole…

Hi Spring fans and welcome to another installment of This Week in Spring! This week I'm in Hong Kong for the amazing YOW! Hong Kong event and then it's off to Singapore for the YOW! Singapore event. If you're in either region, these conferences are world-class events from Australia and they're new in the region so I hope you'll give them a shot.

• Check out this first of many introductions to various aspects of Spring Cloud Data Flow. This first introduction, by Spring Cloud Data Flow ninja Eric Bottard, looks at the Spring Cloud Data Flow shell itself.
• Spring Cloud contributor Ryan Baxter just announced Spring Cloud Edgeware M1. The new release includes updates to the various projects as well as the new Spring Cloud Gateway project. This version is based on Spring Boot 1.5.x.
• Spring Cloud co-founder Spencer Gibb just announced Spring Cloud Finchely M2…

With the new Helm chart for Spring Cloud Data Flow for Kubernetes, there is now a much simpler way of installing the software.

Helm is a package manager for Kubernetes, similar to apt, yum or homebrew. It is very easy to install and it greatly simplifies installation of an application and its dependencies into your Kubernetes cluster. The application package contents and configuration is defined in a chart. When you install it you can override any default configuration values. Helm will install any required services in addition to the ones defined in the chart. For Spring Cloud Data Flow, you have three required services: MySQL and Redis are used as the stores for Spring Cloud Data Flow…

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I was in Beijing, China for the fabulous Spring Summit event which saw technologists from all around China descend on the capitol for a discussion of all things cloud native and Spring. Then I'm off to Shenzhen, China and Hong Kong for customer visits and the epic YOW! Hong Kong show!

• Pivotal have released a commercial version of the Concourse CI pipeline tool for Cloud Foundry. Check it, and Spring Cloud Pipelines, out!
• I liked Bruno Leite's post on error handling in a Spring Boot-based REST API.
• You might like Baeldung's post on using GraphQL with Spring Boot
• This project seems interesting, though I haven't used it yet. It lets you use ModelMapper with Spring Boot applications.
• This is a great find by community legend Tommy Ludwig who noticed that Bitbucket is now running on Spring Boot!

On behalf of the Data Flow team, I am pleased to introduce you to the first of a hopefully long series of posts highlighting features of Data Flow and related projects.

We’ll start gently with a short video discussing the Data Flow shell and some of its features (some of them coming directly from the Spring Shell project) by yours truly.

Topics include:

• TAB completion

• Keyboard shortcuts

• Quotes handling in Spring Shell

• Quotes handling in Data Flow DSL

The reference documentation section mentioned in the video can be found here, while reference on the general Data Flow DSL is here…

Spring Boot 2 brings important changes to Actuator and I am pleased, on behalf of the team, to give you a sneak peek to what’s coming in 2.0.0.M4.

Working on a major new release gives us the opportunity to revisit some of the public contracts and improve them. We quickly felt that the endpoint infrastructure was one of them: currently, the web endpoints in the Actuator are only supported with Spring MVC (no JAX-RS support). Also, creating a new endpoint that exposes several operations requires writing quite a lot of boiler plate: you need to write a main endpoint, the Spring MVC extension (as a @RestController), a JMX MBean and the necessary auto-configuration. As of Spring Boot 2 support for a "reactive" actuator became an obvious requirement that also brings…

Hi Spring fans! Welcome to another installation of This Week in Spring. Can you believe we're already nearing the end of August?? Time sure flies!

Last week and over the weekend I was in Hangzhou, China visiting with Alibaba, talking to a few of the teams using Spring Boot and Spring Cloud at China-scale.

This week I'm in Shanghai, China, where I've been talking to customers and spending a few days with the teams at Microsoft China who are working on the Spring Boot and Pivotal Cloud Foundry integrations for Microsoft Azure. They're doing some amazing work and it's been an honor to hang out with them. Check out all the cool Spring Boot starters that they've built for the various Azure services…
