Concerto for Java and AI

• Spring Boot 3.3 (with Spring AI)

Mousike

First, make sure you have an OpenAI account. Then, define an environment variable with the OpenAI API Key associated to your OpenAI account as the value.

export SPRING_AI_OPENAI_API_KEY=<INSERT KEY HERE>

Finally, run the Spring Boot application.

cd mousike
./gradlew bootTestRun

You can access the application at http://localhost:8080.

If you want to run the application as it was before AI-infusion, run it as follows.

./gradlew bootTestRun --args='--spring.profiles.active=plain'

The application relies on the native Testcontainers support in Spring Boot to spin up a PostgreSQL database with the pgvector extension, and a Grafana LGTM service for observability.

Grafana is listening to port 3000. Check your container runtime to find the port to which is exposed to your localhost and access Grafana from http://localhost:. The credentials are admin/admin.

Structured Data Extraction

http :8080/notes/director/structure text="The movie name is The Last Spring. Let's talk about the first scene, that takes place in a galaxy far far away. Spring is coming. Maybe for the last time. Let's dive right into my notes for each scene time. At seconds 0 0 there should be an uneasy high pitch music that starts rising, growing in intensity and generating suspense. At second 15 I am imagining some percussive instruments that fade in, accompanying the main character towards their inevitable destiny."

Odai

Run the Spring Boot application (exposed through port 9090).

cd odai
./gradlew bootTestRun

The application relies on the native Testcontainers support in Spring Boot to spin up an Ollama service with a mistral model at startup time.
