You know how every Spring Boot exception has its own personality?
Some are calm, some bark all day, and some will destroy your entire project because you missed one annotation 😩
So I decided to imagine what each of them would be — if they were dog breeds. Because if I can’t fix my exceptions, I might as well give them personalities.
🐕 1. NullPointerException: The Labrador
Always excited, always running, and then — BAM 💥 — crashes into the wall because something wasn’t initialized.
Description: Friendly and everywhere, but if you forget to check for null… it’ll take the whole app down.
🐕 2. BeanCreationException: The German Shepherd
Super loyal, but very strict about rules. If even one bean is missing or misconfigured, it’ll bark at you like:
“WHO REGISTERED THIS CLASS WITHOUT @Component?”
🐕 3. HttpMessageNotReadableException: The Chihuahua
Loud, angry, and usually triggered by something tiny — like an extra comma in your JSON.
Mood: “I can’t read this! What is this malformed request body you’ve sent me?!”
🐕 4. DataIntegrityViolationException: The Bulldog
Doesn’t move. Doesn’t care. Will not let you insert duplicate values into that column no matter how nicely you ask.
Vibe: “Primary key means ONE, hooman. ONE.”
🐕 5. CircularDependencyException: The Husky
Loves running in circles. You can fix it ten times, and it’ll still find another way to chase its own tail.
🐕 6. ApplicationContextException: The Dalmatian
You think you’ve seen them all, but every one looks slightly different.
Always appears right before you deploy something important. Spots everywhere (logs, stack traces, everything).
🐕 7. LazyInitializationException: The Beagle
Shows up late to the party, starts sniffing around the database long after the session is closed.
Quote: “Wait, where’s the EntityManager? I just wanted to fetch the relationships!”
🐕 8. ResourceNotFoundException: The Golden Retriever
Tries its best, runs the fetch query, comes back with nothing… still happy though.
Message: “Couldn’t find it, but I love you anyway ❤️”
Which one do you think should be here in the list? 😀
