• Feb 21, 2019 Announcing BIOB an binary object storage library spring-boot I am announcing a new open-source project I am working on: BIOB It is still very early days, but there is already a fully functional local file system implementation and an in-memory implementation for testing. See https://github.com/wimdeblauwe/biob for full details and a usage example on how to use the library in your own project. It does not depend on Spring or Spring Boot, but I have used it in that context so far because that is what I use for all of my projects.

• Aug 30, 2018 Tip on migration to Spring Boot 2 when using Flyway spring-bootflyway Spring Boot 1.5.x uses Flyway 3 while Spring Boot 2.x uses Flyway 5. According to the official migration guide for Spring Boot 2, you need to do 2 releases to be able to migrate an application from Spring Boot 1 to Spring Boot 2 if you are using Flyway: First upgrade your 1.5.x Spring Boot application to Flyway 4 (4.2.0 at the time of writing), see the instructions for Maven and Gradle. Once your schema has been upgraded to Flyway 4, upgrade to Spring Boot 2 and run the migration again to port your application to Flyway 5.
• Jul 6, 2018 Datadog integration with AWS Elastic Beanstalk for Spring Boot application spring-boot If you have an application deployed on AWS Elastic Beanstalk and you want to add Datadog integration to it, then these instructions might help you out. I started out with the instructions at https://www.datadoghq.com/blog/deploy-datadog-aws-elastic-beanstalk/ but they use the older version 5 of the datadog-agent and not the newer version 6. In your source code, you normally have a .ebextensions folder to configure the Elastic Beanstalk deployment. Inside that folder, create the following files (Create directories as needed):

• Oct 8, 2017 Building an AsciidoctorJ extension to execute JavaScript asciidoctor I love using Asciidoctor for writing documentation. I mainly got to know it through the excellent Spring REST Docs project. I wanted to build an extension (kind of a plug-in) for Asciidoctor. As I don’t know Ruby, writing an extension in Ruby was a bit too much. Luckily, there is AsciidoctorJ (The JVM version of Asciidoctor) which lets me write extensions in any JVM language. Here, we will be using plain Java, but Groovy for example would work equally well.
• Sep 20, 2017 Using Spring Boot with JavaFX - Using Spring Profiles javafxspring-boot In the previous post, I showed ./blog/2017/09/18/using-spring-boot-with-javafx/[how to get started with Spring Boot and JavaFX]. Continuing with the same example, we are going to create a new implementation of the CountryService interface that talks to the Open AQ Platform API so the list of countries will be a lot bigger than our HardcodedListCountryService we have now. Using Retrofit First, we add 2 dependencies in our pom.xml to be able to use Retrofit:
• Sep 18, 2017 Using Spring Boot with JavaFX javafxspring-boot In my previous post, I showed how to use JavaFX with the Raspberry Pi 3. I promised there to follow up with a post on using Spring Boot with JavaFX, so here it goes. Just as an example, I will be using the REST API service of the Open AQ Platform API as it is simple and does not require any authentication to get started. Initial Setup We will be using Maven, so we start with a minimal pom.xml that includes the latest Spring Boot version (1.5.7 at the time of writing):
