A Java Spring Boot REST API with PostgreSQL, orchestrated by Aspire via Dockerfile.

• Backend: Java 21 + Spring Boot 3.4
• Database: PostgreSQL + pgAdmin
• AppHost: Standalone AppHost.java with addDockerfile

cd samples/spring-boot-postgres
aspire run

• AddDockerfile for Java applications
• AddPostgres with pgAdmin
• JDBC connection string injection via NOTESDB_JDBCCONNECTIONSTRING env var
• Multi-stage Docker build for Spring Boot

Once running, the API is available at the displayed endpoint:

• GET /api/notes - List all notes
• POST /api/notes - Create a note (JSON body: {"title": "...", "content": "..."})
• GET /api/notes/{id} - Get a specific note
• DELETE /api/notes/{id} - Delete a note

Example using curl:

# Create a note
curl -X POST http://localhost:8080/api/notes \
  -H "Content-Type: application/json" \
  -d '{"title":"Hello","content":"My first note"}'

# List all notes
curl http://localhost:8080/api/notes

# Get a specific note
curl http://localhost:8080/api/notes/1

# Delete a note
curl -X DELETE http://localhost:8080/api/notes/1

pgAdmin is automatically configured and accessible through the Aspire dashboard. Use the connection details provided in the dashboard to connect to the PostgreSQL instance.
