📒 Note App – Spring Boot MVC + JPA + Flyway (CRUD)

A minimal Java app that demonstrates CRUD for a single entity Note using Spring Boot MVC, Thymeleaf, Spring Data JPA, H2, and Flyway.

---

Implemented Features

✅What’s New (Security)

Added dependency: spring-boot-starter-security.

On startup, Spring Boot shows a generated password in logs:

Using generated security password: 6a4b3e7f-...

Default username: user. Enter these credentials at the login page to access the app.

Optional (dev only): to avoid generated passwords each run, you may set fixed creds in application.properties:

spring.security.user.name=admin spring.security.user.password=admin

(Not required by the assignment.)

✅ Entity

Note

• id (Long, auto-generated)
• title (String, required)
• content (String, up to 2000 chars)

✅ Persistence (JPA + Flyway)

• @Entity-annotated Note mapped to table note
• NoteRepository extends JpaRepository<Note, Long>
• Schema managed by Flyway migrations (V1 creates table note)

✅ Service Layer

CRUD operations:

• Create (add)
• Read (getById, getAll)
• Update (update(Note note))
• Delete (deleteById)

✅ Web Layer (Spring MVC) — Routing per mentor spec

NoteController routes:

• GET /note/list — list notes
• GET /note/create — show create form
• POST /note/create — create note
• GET /note/edit?id=123 — show edit form (id in query)
• POST /note/edit — update note (id + fields in body)
• POST /note/delete — delete note (id in body)

✅ UI (Pure HTML + Thymeleaf)

• templates/note/list.html
• templates/note/create.html
• templates/note/edit.html
