When your server is down, it’s stressful. I’ve just recovered from an issue with WordPress where the PHP container was crippling my server because – for reasons I cannot explain – connectivity to the database had just died. This actually happened to me on another server a few months ago, and I wasn’t that bothered … Read more
In this post, we’ll explore how to use Spring Boot and Spring Security to manage access control for our application. Specifically, we’ll look at how to set up user roles to restrict access to certain pages based on the role of the currently logged-in user. This approach makes sure that only authorised users can view … Read more
In this blog post, we’re going to explore what seems like a fairly straightforward process at first glance: adding basic form login to a Spring Boot app. However, as with most things in the Spring Boot and Spring Security ecosystem, it’s rarely as simple as it sounds. There are several hurdles we will encounter on … Read more

In this post, we’re going to explore how to validate an incoming JSON payload in a Spring Boot application. I wanted to use this exercise as a way to learn both validation, and automated testing. So we’re going to see unit tests for the validation logic in isolation, and also how this comes together with … Read more
In this post, we’re continuing with our Spring Boot guestbook example, but this time we’ll be adding persistence by integrating a PostgreSQL database. While the overall process is fairly straightforward and well-documented, there were a few things that caught me off guard along the way. One challenge I faced was integrating Spring Data repositories with … Read more
In this post, I’m going to explore the options available for someone who wants to use their computer primarily by voice. The reason for this exploration is that, last Thursday (at the time of ‘writing’), I had the misfortune of falling off my bike and breaking my collarbone. This is the first time in my … Read more
In this blog post, I will continue building on the Spring Boot guestbook example by taking it a step further and integrating Thymeleaf templates.
