What java-spring-boot does

This skill equips coding assistants with blueprints for modern Spring Boot 3 applications, defaulting to version 3.2. It guides the model through writing REST endpoints and handling payload validation via Java records. Exceptions follow standard problem detail structures.

On the infrastructure side, it outlines stateless SecurityFilterChain beans with OAuth2 JWT support, layered controller-service architecture, and Actuator Prometheus metrics. Because it targets Spring Boot 3, legacy Spring Boot 2 security configurations directly clash with its filter chain conventions.

What it helps with

configure stateless JWT authentication using SecurityFilterChain
build validated REST APIs with custom ProblemDetail exception handlers
expose Actuator health probes and Prometheus metrics in application.yml
set up Spring Data JPA repositories with batching and pagination

Example prompts for the agent

Configure a stateless SecurityFilterChain in Spring Boot 3.2 supporting JWT resource servers.
Write a REST controller for user registration using Java records for input validation.
Set up application.yml to enable Actuator health probes and Prometheus metric endpoints.
