Introduction In this blog post, we explore how to effectively map one-to-many relationships using Spring Boot and PostgreSQL. This relationship type is common in database design, where one entity (e.g., a post) can have multiple related entities (e.g., comments). We'll dive into the implementation details with code snippets and provide insights into best practices.

In our case: Post Entity : Represents a blog post with fields such as id , title , content , and a collection of comments . Comment Entity : Represents comments on posts, including fields like id , content , and a reference to the post it belongs to.
