Maven & MVC in Spring Boot — how I actually understood it
When I started Spring Boot, I kept hearing two words again and again -Maven and MVC.
- At that time I didn’t really get it.
- Still, I didn’t ask… just went with the flow thinking it’ll make sense later.
- This is basically what I undeThat’s pretty much it.understood after struggling a bit.
Maven first.
- When you create a Java project, you don’t just write code and run it.
- You need other stuff — Spring Boot, database drivers, some libraries.
Initially I thought I could handle it manually. Download jars, add them, done.
It works, but only for some time.
After that, small problems start:
wrong versions, something not working, no idea what went wrong.
That’s where Maven helps.
You just write everything in one file (
pom.xml).After that, it takes care of the rest — downloading, managing versions, building.
You don’t really “see” Maven working.
It just does things in the background.
After a point, you stop thinking about it completely.
Now MVC.
- Before this, I used to write everything in one place.
- Controller, logic, data… all mixed.
- It was okay for small code, but once it got bigger, it became confusing.
- MVC just separates things. That’s it.
Controller — where the request comes.
- If you hit something like
/users, it reaches the controller first. - Controller won’t do everything.
- It just decides what should happen next and passes it.
Model — your data.
- Like a User: id, name.
- Nothing complicated.
- Just represents what you’re working with.
View — what goes back.
- In most cases, it’s just JSON.
- User asks → you send data → done.
What made it clear for me was this:
- request → controller → process → response
- That’s the whole flow.
- I was overthinking it before.
One simple way I remember it:
like ordering food.
- You talk to waiter → controller
- Waiter goes inside → model
- Food comes back → view You never go to the kitchen.
- Same thing here.
*One mistake I made — I thought Maven and MVC are related.
*
They’re not.
- MVC is about how you write code.
- Maven is just there handling dependencies and setup.
That’s pretty much it.
- Honestly, reading won’t make it fully click.
- Try a small API, return some data… then it makes sense.
