Extending support for Spring Boot 2.1.6 and Spring Reactive

Extending support for Spring Boot 2.1.6 and Spring Reactive

Red Hat Application Runtimes recently added extended support for the Spring Boot 2.1.6 runtime for Red Hat customers building Spring apps. Red Hat Application Runtimes provides application developers with a variety of application runtimes running on the Red Hat OpenShift Container Platform.

Introduction to Spring Boot

Spring Boot lets you create opinionated Spring-based standalone applications. The Spring Boot runtime also integrates with the OpenShift platform, allowing your services to externalize their configuration, implement health checks, provide resiliency and failover, and much more.

Reactive Spring Boot programming with Vert.x

Reactive Spring Boot programming with Vert.x

The latest bundle of Red Hat supported Spring Boot starters was recently released. In addition to supporting the popular Red Hat products for our Spring Boot customers, the Red Hat Spring Boot team was also busy creating new ones. The most recent technical preview added is a group of Eclipse Vert.x Spring Boot starters, which provide a Spring-native vocabulary for the popular JVM reactive toolkit.

Let’s quickly go through the main concepts to get everybody on the same page before looking into an example.

Extending support to Spring Boot 2.x for Red Hat OpenShift Application Runtimes

Extending support to Spring Boot 2.x for Red Hat OpenShift Application Runtimes

What Red Hat is providing

Red Hat OpenShift Application Runtimes (RHOAR) is a recommended set of products, tools, and components for developing and maintaining cloud-native applications on the Red Hat OpenShift platform. As part of this offering, Red Hat is extending its support to Spring Boot 2 and related frameworks for building modern, production-grade, Java-based cloud-native applications.

Spring Boot lets you create opinionated Spring-based standalone applications. The Spring Boot runtime also integrates with the OpenShift platform, allowing your services to externalize their configuration, implement health checks, provide resiliency and failover, and much more. To learn more about how Spring Boot applications integrate with the wider Red Hat portfolio, check out the following OpenShift Commons Briefing by Thomas Qvarnstrom:

Good news: Business automation is not about SOA

Good news: Business automation is not about SOA

This is not an article about service-oriented architecture (SOA); neither is it a business process management (BPM) article. This article is about how business automation can change the way you create software.

At a first, developers and architects tend to associate the use of BPM suites (or business-oriented architecture) with SOA. This behavior immediately leads to an incorrect bias about the subject.

C-suite executives understand: Transform—or be suppressed by new, disruptive, technology-driven startups. In 2019, business automation is a key transformation that executives will seek in order to improve business performance and lower costs. However, some technology teams are not very open to it. Why?

In the past, BPM suites have been used as big centralized orchestrators for services, external systems, and human tasks. JBoss SOA Platform, released in 2008, is an example of such an integration platform. Unfortunately, this kind of application does not fit new cloud- and microservices-oriented architectures. The good news is that business automation evolved and can help teams to reach the next step in DevOps: BizDevOps.

Eclipse MicroProfile for Spring Boot developers

Eclipse MicroProfile for Spring Boot developers

By now you have probably heard of Eclipse MicroProfile (MP). It is a community-driven initiative to define specifications for enterprise Java microservices. MicroProfile is only two years old, yet it has delivered eight innovative specifications and is evolving fast. It provides metrics, API documentation, health checks, fault tolerance, distributed tracing, and more. With it, you can take full advantage of cutting-edge cloud-native technologies and do it in a vendor-neutral fashion!

For developers familiar with Spring Boot, we have prepared this article, which compares the basics of developing applications with Spring Boot and with MicroProfile. We wrote two applications, one with each solution. In this article, we will go through the differences between them. You can find the source code for both projects on GitHub.

For the MicroProfile application, we use Thorntail (formerly know as Wildfly Swarm), but except for the setting up part, Open Liberty, Payara, TomEE, or any other implementation would look exactly the same.

Throughout this article, we assume you know Spring Boot and we focus on what is different in MicroProfile.

Spring Boot-enabled business process automation with Red Hat Process Automation Manager

With the release of version 7.1 of Red Hat Process Automation Manager (RHPAM), the platform now supports the deployment of the process automation manager runtime as a “capability” within Spring Boot applications. As Maciej Swiderski, the project lead for jBPM.org (the upstream community project for RHPAM) explained earlier this year, the KIE (Knowledge Is Everything) platform on which RHPAM is built provides Spring Boot Starters to quickly build a business application or microservice with process and case execution capabilities using a minimal amount of code.

Red Hat Summit Spotlight: Getting Started with Cloud-Native Apps Lab

Red Hat Summit Spotlight: Getting Started with Cloud-Native Apps Lab

Cloud-native application development is the new paradigm for building applications and although is it often mistaken for microservices, it is much more than that and encompasses not only the application architecture but also the process through which applications are built, deployed, and managed.

New apps are often seen as the focus of cloud-native applications; however, we believe existing and new applications are alike and can incorporate cloud-native practices if they have the four defining characteristics of cloud-native applications:

  • Service-based: Build modular loosely coupled services (for example, microservices).
  • API-driven: Expose services via lightweight technology-agnostic APIs.
  • Containers: Package and deploy in containers as a portable unit of compute.
  • DevOps: Adopt agile and DevOps principles.

The Getting Started with Cloud-Native Apps lab at Red Hat Summit 2018, which takes place in San Francisco on May 8–10, has a packed agenda that focuses on walking participants through the principles of building and operating cloud-native applications.

Unit Testing for Camel Rest DSL and Spring Boot

Unit Testing for Camel Rest DSL and Spring Boot

Hopefully by now, you know how to write your first Rest DSL Camel Route using Spring Boot.  If not, check this post first. Now that you have your route written, it’s time to write a unit test for it.  Many people find Apache Camel unit testing a big struggle to figure out.  Luckily, when using Spring Boot with the Apache Camel Rest DSL testing, a Rest Route isn’t too difficult.

Deploying a Spring Boot App with MySQL on OpenShift

Deploying a Spring Boot App with MySQL on OpenShift

This article shows how to take an existing Spring Boot standalone project that uses MySQL and deploy it on Red Hat OpenShift,  In the process, we’ll create docker images which can be deployed to most container/cloud platforms. I’ll discuss creating a Dockerfile, pushing the container image to an OpenShift registry, and finally creating running pods with the Spring Boot app deployed.

To develop and test using OpenShift on my local machine, I used Red Hat Container Development Kit (CDK), which provides a single-node OpenShift cluster running in a Red Hat Enterprise Linux VM, based on minishift. You can run CDK on top of Windows, macOS, or Red Hat Enterprise Linux.   For testing, I used Red Hat Enterprise Linux Workstation release 7.3. It should work on macOS too.

To create the Spring Boot app I used this article as a guide. I’m using an existing openshift/mysql-56-centos7 docker image to deploy MySQL to  OpenShift.
