Excellent article, with good diagrams.

A question though: What are your thoughts on Lombok (for removing the getters/setters and some boilerplate)?

Also, obviously for a Production system, you might want to tweak things a little (eg, ControllerAdvice for the edge cases when the DB is offline etc, maybe add CircuitBreaker, etc)... but I do understand that the aim of the code was a tutorial, not a Production Ready application.

Lombok can be used. But for big projects it cause some issues. For demo projects it should be fine.

Yeah, it is a complete app. We can do many things to make it better. You are welcome to send a pull request.

We actively use Lombok, across ~50 projects that are all in Production environments.

I'm curious, what problems have you seen with it on "big projects" ?

Thanks, though I asked for your thoughts on it, not someone else's musing on the topic.

To address those points on that external site:

"It's another dependency" - yes, it is, yes, I have to modify the IDE too. But does it follow that I shouldn't deploy into Kubernetes because I have to install kubectl?
"Enourmous coupling, use interfaces instead" - this is more about where Lombok is used, and is a choice of how the workman uses the tool. I wouldn't use a sledgehammer to replace a window in my house.
"Removal of getters and setters hides code" - sure it does. But that doesn't mask anything, and by extension of the "hiding code is bad" argument, surely, no-one should use Spring either!
"Builder hides problems that would be a compile failure" - see javax validation. Your problems just went away.
"Lombok doesn't work with Spring variable injection" - cool, I've never seen a valid use case of having getters/setters in Spring config classes, why would anyone want equals() and hashCode()? Surely the answer is simply "don't use the tool where it's of no benefit!"

So, I ask again, what problems have you (or others) seen with Lombok in big projects?

Please note, I have no vested interest in, or affiliation with, Lombok.

To answer your question, no personally I have never faced the issue. My team leads are against it, so we didn't implement it with lombok.

I won't lie, I came to the post because I'm experienced enough in Spring etc, but was curious about the use of Vue. I was a little disappointed but to see any, but it was a long post.

I also dislike external links.

Still a decent article though.
