暗記ではなく理解、理論ではなく経験で学ぶバックエンド開発入門講座です。

「JPAとは何ですか？」という面接の質問に、検索して出てきた定義を丸暗記して答えるのではなく、「JdbcTemplate地獄を経験したことがあるのですが…」と実体験に基づいた回答ができるようになる講義です。

純粋なJavaのServerSocket 30行が、Spring Bootならわずか7行に短縮される過程を直接体験し、「なぜフレームワークを使うのか」を肌で感じて理解します。

6時間の講義を終える頃には、皆さんの手元にSpring Boot + JPAで構築した「Todo List REST API」という、実際に動作するポートフォリオが完成しているはずです。

신입백엔드

This is an introductory backend development course where you learn through understanding rather than memorization, and experience rather than theory.

Instead of reciting a Googled definition when asked "What is JPA?" in an interview, this course will empower you to give an answer based on experience, starting with "Well, I've been through JdbcTemplate hell..."

You will gain a deep, intuitive understanding of "why we use frameworks" by experiencing firsthand how 30 lines of pure Java ServerSocket code shrink down to just 7 lines in Spring Boot.

After 6 sessions, you will walk away with a functional portfolio piece: a Todo List REST API built with Spring Boot + JPA.
