Out of the box, Spring Boot is very easy to use with the H2 Database. Spring programmers typically prefer writing code against such lightweight in-memory database, rather than on an enterprise database server such as Microsoft SQL Server or Oracle. In-memory databases come with several restrictions making them useful only in the development stages in […]Continue reading
When developing enterprise applications, Spring programmers typically prefer writing data-centric code against a lightweight in-memory database, such as H2 rather than running an enterprise database server such as Oracle, or MySQL.

In my earlier Integration Testing with Spring and JUnit post, I discussed how to test a service bean facade with JUnit. I also posted a video, titled Testing Spring with JUnit on YouTube. In post, Spring Boot Web Application – Part 3 – Spring Data JPA, I showed how to test a Spring Data JPA […]Continue reading
Containers based deployments are rapidly gaining popularity in the enterprise. One of the more popular container solutions is Docker. Many view containers as virtual machines. They’re not. Well, kind of not. A container is a virtual walled environment for your application. It’s literally a ‘container’ inside the host OS. Thus your application works like it […]Continue reading
I’ve been playing with Docker a lot recently to deploy Spring Boot applications. Docker is very cool. I’ve been learning a lot about it. This is my unofficial Docker Cheatsheet. Use with caution! Got any tips and tricks? Comment below, and I’ll try to update this. List all Docker Images docker images -a List All Running […]Continue reading
