I want to add the "java-backend-learning — Copilot Instructions" prompt rules to my project. Repository: https://github.com/matthijsgroen/java-backend-learning Please read the repo to find the rules/prompt file, then: 1. Download it to the correct location (.cursorrules, .windsurfrules, .github/prompts/, or project root — based on the file type) 2. If there's an existing rules file, merge the new rules in rather than overwriting 3. Confirm what was added
Description
Project for dusting off Java/backend knowledge
Project Overview
This is a Spring Boot 4.0.2 dashboarding application using Java 25 with PostgreSQL, organized as a modular monolith using Spring Modulith. The architecture emphasizes module boundaries through package structure.
Module Organization
• Package = Module boundary: Each package under nl.kabisa.dashboarding represents a distinct module • Current modules: • restservice: REST API endpoints (example: greeting service) • dashboard: JPA entity management for dashboards with PostgreSQL/JSONB • widget: Widget management with encrypted secrets and configuration validation • Spring Modulith enforces module boundaries - modules communicate via well-defined interfaces, not direct package access
Key Technologies
• Spring Boot 4.0.2 with Spring Modulith 2.0.2 • Java 25 (uses modern features like records) • PostgreSQL 16 with JSONB support • JPA/Hibernate with automatic schema updates (Jackson databind for JSON support) • Springdoc OpenAPI 3.0.0 for auto-generated API documentation • Maven wrapper for builds (use ./mvnw, not global Maven)
Database Setup
`bash docker compose up # Starts PostgreSQL container ` Database credentials in application.properties: dashboarduser/dashboardpass on localhost:5432/dashboarddb
