Hi, Spring fans! Welcome to another installment of This Week in Spring! It's already April 28th, 2020. I can't even believe it.

The time sure is flying, not just since the last time we spoke in this little blog of ours, but also since I first started writing these roundups the first week of January 2011. In four short months, it'll have been ten years since I officially joined the Spring team! Crazy.

It's also the case that time has flown by since this #COVID19 crisis forced much of the world into lockdown. I am an eternal optimist, and I was wondering if this COVID19 crisis was going to have…

Hi, Spring fans! Welcome to another installment of Spring Tips! In this installment, we'll revisit two topics that we've addressed in two previous videos (distributed tracing and metrics collection) in terms of the superb Tanzu Wavefront observability platform.

The first video of the two videos, as mentioned above, dating way back in early 2017, looked at distributed tracing with spring cloud sleuth and openzipkin. Spring Cloud Sleuth is an abstraction for capturing the flow of messages from one node to another. It's useful to help you see how messages move through a system. Spring cloud sleuth integrates with all the usual ingress and egress points in a Spring Boot application. Make an HTTP request using either the Restteplat or the reactive WebClient or Spring Cloud Feign? It works. Receive an HTTP request to a traditional (Servlet-based) or…

Hi, Spring fans! In this episode Josh Long (@starbuxman) talks to Linux kernel hacker and Linux Real-Time patch founder Steve Rostedt on observing the Linux kernel and on what it sees when it looks at our busy Java and Spring applications.

Hi, Spring fans! Welcome to another installment of Spring tips! in this installment, we're going to look at something that's rather foundational, and something that I wish I'd addressed earlier: configuration. And no, I don't mean functional configuration or java configuration or anything like that, I'm talking about the string values that inform how your code executes. the stuff that you put in application.properites. that configuration.

All configuration in Spring emanates from the Spring Environment abstraction. The Environment is sort of like a dictionary - a map with keys and values. Environment is just an interface through which we can ask questions about, you know, the Environment. The abstraction lives in Spring Framework and was introduced in Spring 3, more than a decade ago. up until that point, there was a focused mechanism to allow integration of configuration called property placeholder resolution. This environment mechanism and the constellation of classes around that interface more than…

Spring Cloud Data Flow team is pleased to announce the first milestone release of 2.5.0.RC1.

This first release candidate of 2.5.0 adds some bug fixes and the following features:

• Support application metadata as part of the Container images. Before this release, we only supported application property whitelisting when using a maven artifact.

• Support for Azure AD integration using OAuth 2.0. Spring Cloud Data Flow, Spring Cloud Skipper servers along with the Spring Cloud Data Flow shell can be configured to integrate with Azure AD for authentication and authorization.

• Removal of Scheduler task launcher component when scheduling tasks. In Spring Cloud Data Flow 2.3.x, the scheduling of tasks was designed to have an intermediate scheduler task launcher component to enhance the continuous deployment user experience. Since this component added some additional complexities and overhead on Kubernetes, the 2.5.x release removed this intermediary task launcher. We also added a migration tool to migrate the schedules from 2.3.x and 2.4.x

Dear Spring community,

With Spring HATEOAS’s recent 1.1.0.M3 release, we bring you a new way to configure clients!

The first step in building hypermedia-based services may be configuring your server, which Spring HATEOAS has provided for a long time through its @EnableHypermediaSupport().

The next major step is building a client that can parse that hypermedia output. This has always been available, but it required you to know some of the deepest innards of the Spring Framework.

Until today.

With the latest version of Spring HATEOAS, it has been made much easier to configure RestTemplate, WebClient, or WebTestClient…

Hi, Spring fans! Welcome to another installment of Spring Tips. In this installment, we're going to look at the new support just released for building Spring Boot applications with GraalVM. We've looked at GraalVM and native images in another Spring Tips when we looked at Spring Fu.

GraalVM is several things. It's a C1 replacement for a standard OpenJDK install. You can listen to this episode of my podcast, A Bootiful Podcast, with GraalVM contributor and Twitter engineer Chris Thalinger, for more details on this use of GraalVM. It lets you run regular Sring…
