Spring Boot Production Cheatsheet The Stuff That Breaks in Production (And How to Fix It)
What this is
This is not a tutorial.
This is a collection of the Spring Boot problems that only show up in production — and what actually fixes them.
Things like:
- @Transactional behaving differently than you expect
- Silent performance killers
- Configuration defaults that are dangerous at scale
- Memory leaks nobody notices until it’s too late
- Security settings that look safe but aren’t
All condensed into a practical cheatsheet you can use while building and debugging real systems.
Who this is for
- Backend engineers working with Spring Boot in real production systems
- Developers who already know Spring, but want to stop breaking production
- Teams tired of debugging the same problems again and again
Not for beginners. No basic explanations.
What you get
- A concise, practical cheatsheet covering:
- Transactions & data consistency
- Performance bottlenecks
- Threading and async pitfalls
- Configuration & environment traps
- Security misconfigurations
- Logging and observability basics
- Real-world failure patterns
- Concrete fixes and recommendations
PDF format. Easy to search and reference.
Why this is different
Most Spring content teaches you how to use the framework.
This teaches you how the framework actually fails in production.
It’s written from production incidents, not from documentation.
Format
- ~6–8 pages
- Instant download
Written by a backend engineer working on large-scale production systems.
Based on real incidents, not theoretical examples.
