Hotel Booking App with SpringBoot, Angular & Payment Gateway

Bootstrap a Spring Boot application using start.spring.io with Maven, Java 21, and dependencies like Spring Web, JPA, Lombok, Security, Postgres, and validation, then prepare for JWT, Jackson, and Stripe.

Connect your hotel app to a MySQL database by adding a model mapper and mapping entities to DTOs, then run the Spring Boot app on port 7070.

Structure the project by creating packages: config, controllers, dtos, entities (model), enums, receptions, notification, payments, prerequisites, services, and security.

Create and use enums for user role, room type, payment status, payment gateway, notification type, and booking status to manage hotel bookings with Stripe.

Design and implement user, room, booking, payment, and notification entities with JPA annotations and Lombok, validations, and relationships to create a cohesive hotel booking data model.

Build and wire user, room, booking, payment, notification, and booking reference repositories with JPA, enabling find by email, room availability checks, room searches, and unique reference validation.

Create dto classes as data transfer intermediaries to move user, room, booking, payment, and login data between client and database, using Lombok and Jackson annotations for clean, standardized responses.

Define not found and value required exceptions, and a global exception handler to return 404, 400, and 500 errors, plus custom authentication and access-denied entry points for 401 and 403.

Convert the user entity to Spring Security user details using a builder. Implement a custom user service to load by email and assign authorities from roles.

Develop a jwt utils class to generate and validate tokens for users, with a six-month expiration and a secret key from properties, supporting token creation, username extraction, and validation.

Implement a JWT-based auth filter and security filter chain in a Spring Boot app, extract bearer tokens, validate users, and configure public versus protected API routes.

Configure an email notification service for a hotel booking app using spring boot, sending emails on bookings and payments via java mail sender, persisting notifications in a repository.

Test email notifications for bookings and payments by sending a dummy message via the notification service in a Spring Boot app using async processing and a post construct trigger.

Design and implement a robust user service for a hotel booking app, including register, login, account management, and booking history, with password encoding, jwt tokens, and dto mapping.

Develop an auth controller for a hotel booking app, exposing public login and register endpoints at /api/auth, validating registration and login requests, and returning a standardized response entity.

Test the auth API using Postman by creating a register request to localhost:7070/api/art/register with a JSON body, then verify user registration, roles, and activation.

Create a users controller in a Spring Boot backend for hotel booking, enabling admin-only access to get all users and support updating, deleting, and viewing account details and bookings.

Learn to test the hotel booking app's users API using postman. Verify login generates a token, enforce admin vs customer access, and perform account updates, deletions, and booking checks.

Implement room service to add, update, fetch, delete rooms and search by date range and room type. Handle image uploads and store image URLs, with DTO-to-entity mapping.

Develop a room controller in Spring Boot, handling add, update, delete, and retrieval operations via api/rooms, with multipart form data, room types, and availability checks.

Test the room API end-to-end using Postman, including add, update, get, and delete operations with admin authentication, enums, and image uploads. Validate available rooms queries with check-in and check-out dates.

Learn to implement a full booking service in a hotel app: create bookings, validate dates, calculate price, generate a unique reference, and send payment links via email with repository integration.

Develop a Spring Boot booking controller exposing api/bookings endpoints for get all, create, find by reference, and update bookings, with admin and customer roles enforced.

Test the hotel booking API with Postman, performing get all bookings, create booking, and update booking under admin authorization; verify booking references and email confirmations.

Set up and integrate stripe payments in a hotel booking app, create payment intents, validate bookings and amounts, and update booking status with email notifications after payment.

Create a payment controller wired to a payment service, implement initialize payment via post to /api/payments, support update payment booking, return a response entity, and enforce authorization.

learn to set up the angular frontend by installing the angular CLI, updating to angular 19, and creating a new project with ng new, choosing css and disabling server-side rendering.

Set up and run an angular app in Visual Studio Code, install Stripe and crypto-js, enable token encoding for secure authentication, and verify the app on port 4200.

Develop and secure an api service for a hotel booking app, implementing http calls, token encryption in local storage, guarded routes, and endpoints for auth, profile, bookings, rooms, and payments.

This lecture explains implementing a guard service with canActivate, using an api service and router to enforce admin and authenticated access, redirect to login, and return users to their route.

Generate standalone navbar and footer components in an Angular 19 app, connect them with router links, and implement auth-driven navigation for guests, customers, and admins.

Develop a pagination component to paginate room results on the all rooms page, using Angular directives and the common module to show ten rooms per page.

Build and display room search results using a room result component, showing image, type, price, and description with admin edit options, customer view or book actions, and pagination controls.

Build a room search component that passes check in date, check out date, and room type to an API to fetch and emit available rooms for the room resort display.

Implement registration and login in angular by generating login and register components, wiring an API service and router, using two way bound forms, and navigating to login on success.

Implement an Angular login page that validates email and password, calls the API service, and on success encrypts and stores token and user data, then navigates to home.

Generate profile and edit profile components, fetch user and bookings via API, display them, and protect routes with a guard that redirects to login.

learn to implement an edit profile page in an angular app, including fetch user details, display profile data, and delete account flow, with a future update feature for user details.
