“How to build SpringBoot Token Based Authentication Example?” is one of the most common questions for Java development world. So in the tutorial, I will introduce how to build it with clearly architecture and coding examples.

## Spring Security JWT Architecture – Springboot Token Based Authentication Example

This is diagram for Spring Security/JWT (Springboot Token Based Authentication Example) classes that are separated into 3 layers:
– HTTP
– Spring Security
– REST API

Look at the diagram above, we can easily associate these components with Spring Security Authentication process: receive HTTP request, filter, authenticate, store Authentication data, generate token, get User details, authorize, handle exception…

## PROJECT STRUCTURE FOR SPRINGBOOT TOKEN BASED AUTHENTICATION EXAMPLE

– model package defines 2 entities User & Role that have many-to-many relationship:

– repository package contains interfaces that use Hibernate JPA to store/retrieve data from MySQL database.
– controller package defines RestAPIs for user signup/signin and testing protected resources that is secured with JWT.
– message package defines payload data transferred from user agents (Browser/RestClient…) to RestAPIs and message back.
– security package is the main part of the project that implements JWT security.

## GOAL
In the tutorial “Springboot Token Based Authentication Example”, we expose 2 RestAPIs to signup and signin:
