This is Demo for Spring Boot & Angular 8 JWT Authentication.
In this tutorial, I will show you how to build a full stack Angular 8 + Spring Boot JWT Authentication example.
The back-end server uses Spring Boot with Spring Security for JWT authentication and Spring Data JPA for interacting with database.
The front-end will be built using Angular 8 with HttpInterceptor & Form validation.
You can find the step by step to build this system at:

In this tutorial, I will show you how to build a full stack Angular 12 + Spring Boot JWT Authentication example. The back-end server uses Spring Boot with Spring Security for JWT Authentication & Role based Authorization, Spring Data JPA for interacting with database. The front-end will be built using Angular 12 with HttpInterceptor & Form validation.

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.
Github Source code:
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).
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 Registration
api/auth/signinfor User Login
If Client wants to send request to protected data/endpoints, a legal JWT must be added to HTTP Authorization Header.

What is 2FA
Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account.
Employing a 2FA mechanism is a vast improvement in security over the Singe-Factor Authentication method of simply employing a username and password. Using this method, accounts that have 2FA enabled, require the user to enter a one-time passcode that is generated by an external application. The 2FA passcode (usually a six-digit number) is required to be input into the passcode field before access is granted. The 2FA input is usually required directly after the username and password are entered by the client.

Tutorial: Angular 10 Spring Boot JWT Authentication Example with Angular 10 + MySQl + Spring Security
In tutorial ‘Angular 11 Spring Boot JWT Token Based Authentication Example’, I guide you very clearly how to implement full stack example to demonistrade an jwt token based authentication flow from frontend Angular 11 to backend: SpringBoot and MySQL.
– I give you an Epic of the application, a fullstack excutive flow from frontend Angular 11 to backend jwt SpringBoot Security to database (MySQL/PostgreSQL) with overall architecture diagram.
– I give you a layer diagram of Angular 11 Jwt Authentication application with localStorage and Angular HttpClient (plus Interceptor)
– I guide you detail-steps how to implement a security SpringBoot Jwt Token Authentication.
– I guide you step by step how to develop a Angular 11 Jwt Authentication application.
– Finally, I do an integrative testing from Angular 11 to Jwt Based Token SpringBoot Security RestApis.
We will build an application, from frontend (Angular 11) to backend (Spring Boot), which allows users to register, login account. This application is secured with JWT (JSON Web Token) authentication and Spring Security. Then, depending on the role of current User (user, pm or admin), this system accepts what he can access:
The diagram below show how our system handles User Registration and User Login processes:
This is diagram for SpringBoot Token based authentication Security/JWT classes that are separated into 3 layers:
– Spring Security
– REST API
– SecurityContextHolder provides access to the SecurityContext.
– SecurityContext holds the Authentication and possibly request-specific security information.
– Authentication represents the principal which includes GrantedAuthority that reflects the application-wide permissions granted to a principal.
– UserDetails contains necessary information to build an Authentication object from DAOs or other source of security data.
– UserDetailsService helps to create a UserDetails from a String-based username and is usually used by AuthenticationProvider.
– JwtAuthTokenFilter (extends OncePerRequestFilter) pre-processes HTTP request, from Token, create Authentication and populate it to SecurityContext.
– JwtProvider validates, parses token String or generates token String from UserDetails.
– UsernamePasswordAuthenticationToken gets username/password from login Request and combines into an instance of Authentication interface.
– AuthenticationManager uses DaoAuthenticationProvider (with help of UserDetailsService & PasswordEncoder) to validate instance of UsernamePasswordAuthenticationToken, then returns a fully populated Authentication instance on successful authentication.
– SecurityContext is established by calling SecurityContextHolder.getContext().setAuthentication(…) with returned authentication object above.
– AuthenticationEntryPoint handles AuthenticationException.
– Access to Restful API is protected by HTTPSecurity and authorized with Method Security Expressions.
In the tutorial, “Angular 11 Spring Boot JWT Authentication Example”, we need the Angular HTTP Interceptor to add JWT Authentication Token Based for Security:
– app.component is the parent component that contains routerLink and router-outlet for routing. It also has an authority variable as the condition for displaying items on navigation bar.
– user.component, pm.component, admin.component correspond to Angular Components for User Board, PM Board, Admin Board. Each Board uses user.service to access authority data.
– register.component contains User Registration form, submission of the form will call auth.service.
– login.component contains User Login form, submission of the form will call auth.service and token-storage.service.
– user.service gets access to authority data from Server using Angular HttpClient ($http service).
– auth.service handles authentication and signup actions with Server using Angular HttpClient ($http service).
– every HTTP request by $http service will be inspected and transformed before being sent to the Server by auth-interceptor (implements HttpInterceptor).
– auth-interceptor check and get Token from token-storage.service to add the Token to Authorization Header of the HTTP Requests.
– token-storage.service manages Token inside Browser’s sessionStorage.

In every application, Authentication is the first layer of protection. Thus, Authentication is a major part of Application Security and in this post we will dive deep into the architecture used by **Spring Security **for Authentication.
What is Authentication?_ Authentication is proving who you are. For example, your Identity Card is used to “authenticate” you in your School/College/Office campus._
Spring Security provides excellent support for Authentication by default. Kind of in a plug-in-and-play fashion. A simple Authentication workflow is really easy to setup. However, if you wanna go for a complete custom implementation then you need to understand the authentication flow and comprehend what happens behind the scenes when an authentication request is received by the server.
