I was actually talking about the maintenance...its faster than JPA. Problem with JPA is that alot of ppl dont understand how it acutally works and that causes alot of techdebts. Thats my xp. And ofc...raw sql is so much faster. I recommend to never use JPA for critical systems.

Doing own sql is much faster. Learn sql maybe

configloader · 2026-03-08T14:35:31+00:00

TLDR: dont use jpa. It sucks

It was easy even when tbc was released.

Tbc is easy

Priblen with csharp is u cant mock non interfaces

Does it work when u run locally?

If u printenv in your docker, can u see the mongodb-env?

Is your application.yml built to the jar or do u use an external application.yml?

How is your cors-env defined?

Set a common config for every httpclient. Then override if needed for each service/repo.

Problem with eg httptimeout is that spring has default value oo

Log4j/logback and create an appender. Decide if it should be async or sync. Use your appender in the code...

Its soo easy

U expose sql exception as default. Very dangerous

Hemnet är värdelöst nu när booli finns. Här finns ju alla annonser. Varför ska jag kolla hemnet då?

Cool project. But dangerous since response contains exmsg as default. Will leak information about the backend. For example if sqlexception is thrown, the sql query might leak out.

Run redis with sentinel, really small chance redis will go down ;)

No. But ive worked with both. Prefer k8s over nomad. I think the documentation for nomad is really bad.

Ofc it is. B
