Spring Boot API Design Standards

Priority: P0 (CRITICAL)

Implementation Guidelines

OpenAPI (Swagger)

• SpringDoc: Use springdoc-openapi-starter-webmvc-ui.
• Annotations: Use @Operation and @ApiResponse. Keep clean.
• Schema: Define examples in @Schema on DTOs.

API Versioning

• Strategy: Prefer URI Versioning (/api/v1/) for caching simplicity.
• Deprecation: Use @Deprecated + OpenAPI flag.
