This is part 4 of the blog series in which we are introducing java functions for Spring Cloud Stream applications.

Other parts in the series.

Part 1 - General Introduction

Part 2 - Function Composition

Part 3 - Supplier function and Source application

In the last blog in this series, we saw how we can use a java.util.function.Supplier to generate a Spring Cloud Stream source. In this new edition, we will see how a consuming function can be developed and tested using java.util.function.Consumer and java.util.function.Function. Later on, we will briefly explain the generation of a Spring Cloud…

Dear Spring Community,

I am happy to announce the 4.7.1 release of the Spring Tools 4 for Eclipse, Visual Studio Code, and Theia.

Highlights from this release include:

• (Spring Boot) enhancement: Syntax check for Annotations with Spring Expression Language (#475)
• (Spring Boot) fixed: hard to reproduce BadLocationException inside of language server fixed now, occurred e.g. in (#451)
• (Eclipse) new: early access update sites and distribution builds for Eclipse 2020-09 available now (and requires JDK11 to run)
• (Eclipse) improvement: old Spring Boot launch configs are now "fixed" automatically to exclude test classes again
• (Eclipse) improvement: new Spring Symbols view now works a lot better when selecting the file scope (also takes selections…

Dear Spring community,

Spring HATEOAS 1.1.1.RELEASE is out, the first patched release of the latest stable line, supporting Spring Boot 2.3.

Among many things, you’ll find:

• We are now listing community-led efforts to implement other media types. JSON:API and Siren are the latest. You want to add another media type? Just check out the details.

• VndErrors is a media type for reporting, well, errors. And it has had a sneaky bug that crept in that we’ve now patched. "logref" values are no longer confined to integers. It’s important to also note that the VndErrors spec is showing no signs of life, hence we’ve deprecated its support. If you’re starting a new hypermedia-driven project, our recommendation is to use RFC-7807’s application/problem+json format instead. The API is more elegant and more importantly, under active development. And we’ve made some fixes based on community feedback.

Hi Spring fans! In this installment Josh Long (@starbuxman) talks about yaks, the implicit tension in systems design, and then talks with Josh Lock (@hi_joshuagl) (Levenshtein distance: 2!) about supply chain security, Docker trust, TUF, and more.

Other parts in the series.

Part 1 - General Introduction

Part 2 - Function Composition

In the last two blogs in this series, we provided a general introduction to this new initiative of migrating all the existing Spring Cloud Stream App Starters to functions and the various ways in which we can compose them. In this blog, we continue the series, showing how these functions are developed, tested, and used to generate Spring Cloud Stream applications. In particular, here we are focusing on how to write a supplier function (implementing java.util.function.Supplier…
