Spring Boot Custom Authentication Provider

This project demonstrates how to implement a custom authentication provider in a Spring Boot application. By using a custom authentication provider, you can extend the default authentication mechanism provided by Spring Security and integrate your own authentication logic.

Prerequisites

• Java Development Kit (JDK) 8 or later
• Spring Boot 2.x
• Maven build tool

Getting Started

Follow these instructions to get a local copy of the project and run it on your machine.

1. Clone the repository:

   git clone https://github.com/dewantrie/springboot-custom-authentication-provider.git
   

2. Navigate to the project directory:

   cd springboot-custom-authentication-provider
   

3. Build the project using Maven or Gradle:

   • Maven:

     mvn clean package
     

4. Run the application:

   java -jar target/springboot-custom-authentication-provider.jar
   

5. The application should now be running locally on http://localhost:8081.

Configuration

To configure and customize the authentication provider, modify the CustomAuthenticationProvider class in the project. This class implement the AuthenticationProvider provided by Spring Security and overrides the authenticate method to implement your own authentication logic.

In addition, you can modify the Spring Security configuration in the SecurityConfig class to specify which URLs require authentication and other security-related settings.
