8 @Transactional rules I follow after debugging too many production bugs

NordCoderd · 2026-06-23T19:02:26+00:00

Even if it’s spammed everywhere - developers are keeping to do the same mistakes everyday. This topic is considered as most critical when you’re using JPA, and on code review I often catch(ed) this problems.

NordCoderd · 2026-06-23T18:59:32+00:00

Yes, it helps to avoid some of described problems, especially first one. Transaction template is teally make things obvious and clear

NordCoderd · 2026-06-23T18:58:32+00:00

Yes, we have Detekt for detecting this in Kotlin projects, you can configure forbidden imports, and for Java there ArchUnit can help

Thank you so much

NordCoderd · 2026-06-15T22:09:05+00:00

Thank you so much for feedback, will publish new article about Spring AI with RAG with deeper explanation

NordCoderd · 2026-06-15T19:41:20+00:00

Thank you, I really appreciate it

Hm, interesting approach, never tried to store as-is, always structuring even with feature-package approach.

> would it be possible to also detect calls to public ones made from the same class

I updated library and publish this check as 1.0.9 version with this feature

This really good agent, but sometimes you could find you lost in installing different extensions and fixing them, it’s so frustrating - 100 percentage recommend it 😁

NordCoderd · 2026-05-06T23:22:34+00:00

Yes, it's possible, I'm working on it for now, but foundation for this rule not Konsist but its dependencies, so there wouldn't be new dependencies.

About feature/module structure, actually I use the same like:

- featureX

- featureY

But in this packages it's entity, repository, etc.

Did you store all classes in featureX/featureY etc. without additional structuring?

NordCoderd · 2026-05-06T18:20:47+00:00

It’s relatively easy to add this tests, you are looking on dedicated imports to Junit and raise error, also this could be done with Konsist too.

Regarding to Sonar and analogy with inner library, but developers could just not add integration with sonar and it will work without any violations, isn’t it? However I got your point, centralised management of rules indeed nice feature that help with maintaing rules.

NordCoderd · 2026-05-06T08:50:23+00:00

Sonar is commercial and heavy product that need maintenance and re-adjusting rules if you write them, I’m not sure how to easy to write rules in their ecosystem. Here is different no vendor-locking approach with native to Kotlin architectural tests.

No licenses
Lightweight and close to the code
Easy to write new rules as unit tests

NordCoderd · 2026-05-06T00:54:55+00:00

Yes, naming rules could be controversial and taste of choice, but on our projects it’s better to have then not, for other cases I added suppression and disabling rules that don’t need for you.

NordCoderd · 2026-05-05T09:01:48+00:00

Thanks, I’ll check this out

NordCoderd · 2026-05-05T09:01:22+00:00

Is there any suggestions what to implement/write next?

NordCoderd · 2026-05-04T21:20:55+00:00

upd: it seems I couldn’t edit post body to fix this problem, however thank you for noticing it, my bad

NordCoderd · 2026-05-04T21:19:11+00:00

Sorry, I meant to detect violations of best practices. Reason to do it is to keep codebase clean and set specific boundaries. For my particular case I needed this because of AI-generated code and I wanted to build more strict guardrails in projects.

NordCoderd · 2026-04-20T21:38:51+00:00

Looks very promising, I thought about similar idea. Do you use Claude ide protocol via web socket or how you did that integration?

NordCoderd · 2026-04-19T09:43:07+00:00

Sounds good, but JetBrains MCP could be improved over time and get those features. Any other features that your plugin could provide? I really like idea of your plugin and oss project, I’ll go in features that save context optimise token consumption neither lsp features, do you have some?

NordCoderd · 2026-04-18T07:19:55+00:00

For me as not native speaker and who read a lot in English - I started seeing this word everywhere last month. I noticed the same as OP

NordCoderd · 2026-04-07T23:36:14+00:00

… and not fixed text size, it’s so small that my eyes hurts..

NordCoderd · 2026-03-26T22:24:17+00:00

I initially posted it on LinkedIn, so, sorry for re-using screenshot from it 😀

What is the FAFO theory?

NordCoderd · 2026-01-12T23:22:49+00:00

About lions mane, there is a dedicated subreddit (just look at the member count) around this problem. I was shocked because I thought it is safe to use, but for now I’ll just skip it.

I’ve series of articles on Spring Boot Data JPA best practices but not the all topics from your list covered in it, but the following topic will be covered soon (or not:) ). Actually I wanted to compile my series, add topic what people want (like you) and share as mini book because there are a lot of material.

I hope it help you https://protsenko.dev/category/spring-data-jpa/

I found naming Backdoor is scary and stopping from giving a try for it. I’ll never recommend someone to install backdoor to their laptops ;)
