Build a Blog Platform API with Spring Boot

Problem/Feature Description

A content team needs a REST API for their blogging platform. The API is built with Spring Boot and Java. A Next.js frontend hosted on a different domain will consume it. The API will run on Kubernetes behind an ingress controller.

The API needs the following endpoints:

• GET /api/posts -- list all published posts (supports ?page=1&size=10 pagination)
• GET /api/posts/{slug} -- get a single post by URL slug
• POST /api/posts -- create a new blog post (accepts title, content, tags array, authorName)
• PATCH /api/posts/{slug} -- update an existing post
• DELETE /api/posts/{slug} -- delete a post
• POST /api/posts/{slug}/comments -- add a comment (accepts authorName, body)
• GET /api/posts/{slug}/comments -- list comments for a post

Use an in-memory data store. Posts should have id, title, slug, content, tags, authorName, comments, published, and createdAt fields. Generate slugs from titles.
