Problem description (optional)

No response

Desired solution

Spring Boot 3.4.0 got some new exciting features we could investigate to simplify some things and get rid of boilerplate code, e.g.:

• Structured Logging (Logstash Support built-in, might be able to remove custom configuration)
• Support in Testcontainers for Hazelcast
• Improved Observability with Application Groups

Keep in mind this issue also affects https://github.com/it-at-m/refarch.

Structured Logging (Logstash Support built-in, might be able to remove custom configuration)

The current custom configuration also adds the ShortenedThrowableConverter to stay under the docker 16kb per logline limit with long stacktraces.

This part is currently not configurable with the new Spring Boot Structured Logging options 😢

Okay but we still might be able to at least remove the explicit logstash dependecy as its managed by Spring boot? Did you take a look at this?

Spring Boot did not introduce a dependency on the Logback Logstash encoder library, it implements the correct format encoding by itself (directly part of the Spring Boot logging package).
