Case Study: Build and Run a Streaming Application Using an HTTP Source and a JDBC Sink

Engineering | David Turanski | August 10, 2020 | ...

Introduction

So far in this series we have introduced the new stream applications based on Java functions, and function composition. We have also provided detailed examples of how to build a source from a supplier and a sink from a consumer. Here we continue the journey with the first of several case studies to follow. Each case study demonstrates how to use one or more of the available pre-packaged Spring Boot stream applications, in various scenarios, to build data streaming pipelines.

Today we will showcase two of the most commonly used applications, the HTTP source and the JDBC sink. We will use them to build a simple service that accepts HTTP POST requests and saves the contents to a database table. We will first run these as standalone Spring Cloud Stream applications, and then show how to orchestrate the same pipeline with Spring Cloud Data Flow

Spring Web Services Samples have been updated!

Engineering | Greg L. Turnquist | August 10, 2020 | ...

Dear Spring community,

Spring Web Services Samples (spring-ws-samples) has been upgraded!

You might have known this, but many parts of this collection of samples goes all the way back to 2006. Today, I am happy to report it has been updated in a multitude of ways.

  • Introduction to Spring Boot

  • Introduction to Spring Data

  • Removal of outdated technologies

  • Removal of redundant samples

This was a hard-won task that took me several weeks, but based on the incredible persistence of SOAP, it was something that had to be done to serve the Spring community.

Hi, Spring fans! Welcome to another installment of This Week in Spring!

How're you all doing? Me? I'm doing swell! I was so happy to celebrate my tenth anniversary on the Spring team on the 2nd of August, 2020.

Spring Cloud Data Flow 2.6.0 Released

Releases | Janne Valkealahti | August 04, 2020 | ...

Spring Cloud Data Flow team is pleased to announce the release of 2.6.0.

This 2.6.0 adds usual bug fixes and the following key highlights:

  • Wavefront New integration to monitor streams and tasks using Wavefront. More about this feature can be found from Stream Monitoring and Task Monitoring

  • Platform Support for Scheduling Tasks scheduling now have a platform support. See Scheduling Tasks

  • Java CFEnv We're now on a new version of Java CFEnv which greatly improves user experience when there is a need to bind to user created services.

  • Bitnami We've moved from a Helm Hub to Bitnami as a helm chart storage.

  • Composed Task Runner as SCDF native module Composed Task Runner is now an integral part of SCDF itself and gets registered implicitly while the users who have the custom composed task runner can still override the native one. This enables us to integrate the composed tasks management within the context of Spring Cloud Data Flow.

Creating a function for consuming data and generating Spring Cloud Stream Sink applications

Engineering | Soby Chacko | August 03, 2020 | ...

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…

Spring HATEOAS 1.1.1.RELEASE is out!

Releases | Greg L. Turnquist | July 30, 2020 | ...

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.
