Ideas and notes on software development…
I have been using the `quay.io/keycloak/keycloak:19.0.3-legacy` with docker compose and JHipster. Now, JHipster application exposes UI to 8080, keycloak also exposes to 8080, so we map it to another port, say 9080. JHipster app talks to the keycloak via service name and port, like so: keycloak:8080, and all works fine until you try to login,…
After, apparently, encountering a JPA bug with delete all by in the repository, I had to figure out the best approach to run a delete by query. Using named query on the entity seems to work just as expected, so I am posting the link to the solution here as a reference: https://medium.com/the-full-stack-developer/how-to-delete-records-in-spring-data-based-on-multiple-values-563500ad51cc
In existing table with data populated, changing the column type from string to text requires some migration. For large data type, Postgres stores the data in a separate location and just references it by using an ID. This means that, until then, column data would be a string content and after the change, it would…

I have been trying to create a clean hexagonal architecture example with SpringBoot. More complex approaches are possible, by introducing the CQRS into the equation, but I believe that just over complicates the architecture and if there is no really good reason for it, I’d avoid it. There are a couple of examples out there…
Here is a small example that: Uses @DataJpaTest annotation to bring in only configuration relevant for JPA tests (entities, repos etc…) Uses @TestMethodOrder(MethodOrderer.OrderAnnotation.class) and @Order annotations to enforce order of method execution Uses @ComponentScan(basePackages = {“tech.dimitar.rosdjpaint.bootstrap”}) annotation to bring in the component that bootstraps the data Uses @Commit annotation on test to enforce transaction does…
