[Java] Spring Boot: Enable JSON TLS

[Kaliumhexacyanoferrat]

Description

There seems to be no way to configure multiple endpoints via application.yaml so we use the same way as was already used by @asvanberg

PR Commands — comment on this PR to trigger (requires collaborator approval):

Command	Description
/benchmark -f <framework>	Run all benchmark tests
/benchmark -f <framework> -t <test>	Run a specific test
/benchmark -f <framework> --save	Run and save results (updates leaderboard on merge)

Always specify -f <framework>. Results are automatically compared against the current leaderboard.

Run benchmarks locally

You can validate and benchmark your framework locally with the lite script — no CPU pinning, fixed connection counts, all load generators run in Docker.

./scripts/validate.sh <framework>
./scripts/benchmark-lite.sh <framework> baseline
./scripts/benchmark-lite.sh --load-threads 4 <framework>

Requirements: Docker Engine on Linux. Load generators (gcannon, h2load, h2load-h3, wrk, ghz) are built as self-contained Docker images on first run.
