Spring Boot Development in Derry
Building services with Spring Boot for Derry organisations, where what starts is assembled from what is present. Auto-configuration inspects the classpath and wires up a great deal without any of it appearing in your code — which is why adding a dependency can change behaviour, and why debugging starts with knowing what was configured on your behalf.
Why this comes up
The problem
A dependency was added for one utility, it brought auto-configuration with it, and the application now behaves differently.
What you get
What we deliver
- Auto-configuration reports used, so what is active is known rather than assumed
- Starters chosen deliberately, since each brings behaviour as well as libraries
- Configuration externalised properly, with profiles for each environment
- Beans and their scopes defined explicitly where the defaults do not suit
- Actuator endpoints enabled for health and metrics, and secured appropriately
- Tests using slices rather than starting the whole context every time

Spring Boot Development in Derry — common questions
- How do we know what was auto-configured?
- Ask the application. It can report which configurations were applied and which were skipped and why, and reading that report is the fastest route to understanding behaviour nobody wrote — most developers never run it and it answers the question directly.
- Why can adding a dependency change behaviour?
- Because auto-configuration reacts to what is on the classpath. A library added for one class can activate a whole configuration — a different connection pool, a security default — which is convenient when intended and confusing when not.
- How should tests be structured?
- With slices that load only the layer under test. Starting the full application context for every test makes a suite slow enough that developers stop running it, and most tests need a fraction of what a full start-up provides.
- Should Actuator be exposed?
- Enabled, and secured. Health and metrics endpoints are genuinely useful for operating the service and some expose information that should not be public — so the useful position is on with access controlled, rather than off or open.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
