Hospital Patients — Spring Boot MVC + Thymeleaf

A focused Spring Boot MVC + Thymeleaf web app: a paginated patient table (3 per page), search by name via a derived query, delete with confirmation, and a shared decorated layout — seeded with a profile-guarded CommandLineRunner and tested with MockMvc on H2.

Deep Dive

A compact, well-tested Spring MVC + Thymeleaf patient app — the clean MVC baseline before security and validation are layered on.

Features

  • ▸📋 Paginated patient list (3 per page)
  • ▸🔎 Search by name via the derived query findByNomContains
  • ▸🗑️ Delete a patient (with confirmation)
  • ▸🎨 Shared layout (template1.html) applied through layout decoration

Architecture

web/         → PatientController (@Controller, pagination & search)
repository/  → PatientRepository (JpaRepository + query derivation)
entities/    → Patient (JPA entity, Lombok @Data/@Builder)
templates/   → patients.html decorated by template1.html

Engineering polish

  • ▸Fixed Thymeleaf layout syntax: layout:decorate="template1" → layout:decorate="~{template1}"
  • ▸Moved data rows into <tbody>
  • ▸Seed data via @Bean CommandLineRunner guarded with @Profile("!test")
  • ▸Added an H2 test profile and MockMvc web tests

Runs on :8084/index with MySQL (or H2 for tests), Bootstrap 5 via WebJars.
