In this tutorial, I will show you how to build a full stack Angular 11 + Spring Boot JWT Authentication example. The back-end server uses Spring Boot with Spring Security for JWT Authentication & Authorization, Spring Data JPA for interacting with database. The front-end will be built using Angular 11 with HttpInterceptor & Form validation.
It will be a full stack, with Spring Boot for back-end and Angular 11 for front-end. The system is secured by Spring Security with JWT Authentication.
User can signup new account, login with username & password. Authorization by the role of the User (admin, moderator, user) Screenshots Here are UI screenshots of our system.
– Anyone can access a public page before logging in:
– New user registration:
– Signup Form Validation:
– After signup is successful, User can login:
-Loggedin User can access Profile page/ User page:
– This is UI for admin:
– If a User who doesn’t have Admin role tries to access Admin/Moderator Board page:
This is full Angular + Spring Boot JWT authentication demo (with form validation, check signup username/email duplicates, test authorization with 3 roles: Admin, Moderator, User).
The diagram shows flow for User Registration process and User Login process. 
It’s not too difficult to understand. We have 2 endpoints for authentication:
api/auth/signupfor User Registrationapi/auth/signinfor User Login
If Client wants to send request to protected data/endpoints, a legal JWT must be added to HTTP Authorization Header.
