Spring Boot API Gateway with Auth Server and JWT Example

Overview

This project serves as an example of implementing an API Gateway to manage authentication and routing for microservices in a Spring Boot environment. It showcases the following components:

API Gateway: Centralized entry point for handling requests, routing them to the appropriate microservices, and managing authentication using JWT.
Authentication Server: Provides authentication and issues JWT tokens to users.
Eureka Server: Service registry for service discovery.
Config Server: Centralized configuration management for microservices.

Prerequisites

Before running this project, ensure you have the following installed:

Java Development Kit (JDK) 17 or higher
Gradle
Docker (optional, for running Eureka Server and Config Server in containers)

Installation

Clone this repository:

git clone https://github.com/JuanCarlosAguilarB/apigateway-with-auth-server-spring-boot.git

Build the project:
```
cd spring-boot-api-gateway-example
```

Run Eureka Server and Config Server (if not using Docker):

# Assuming you have Docker installed
docker-compose up -d

Usage

Access the Eureka Server dashboard to ensure all microservices are registered:
```
http://localhost:8761/
```
Obtain JWT tokens from the Authentication Server:
```
POST http://localhost:8081/login/v1/
```
Include the client credentials and user credentials in the request body. Refer to the Authentication Server documentation for details.
Use the obtained JWT token to access protected resources via the API Gateway.
