Multi-agents system

To demonstrate Agent-to-Agent communication using ActiveMQ and provides a basic setup for handling user authentication / authorization using JWT tokens.

Technologies

• Spring Boot - 2.7.3
• Maven - Dependency Management
• ActiveMQ - Message Broker (https://activemq.apache.org/)
• Spring Security
• JWT Authentication (https://jwt.io/introduction)
• Spring Datasource, JPA, App properties
• PostgreSQL - Relational Database Management System

Prerequisites

• Java 8 or later
• PostgreSQL installed and running on your machine
• ActiveMQ installed and running on your machine

Getting Started

Configure the Database

Create a database named postgres in PostgreSQL, and update the database connection properties in application.properties.

Running the Application

You can run the application using Maven. Navigate to the project directory and run the following command:

mvn spring-boot:run

This will start the Spring Boot application and make it accessible at http://localhost:8080.

To access ActiveMQ admin page, you may go to http://localhost:8161/admin (user, password are admin, admin)

Testing the Application

In this example we need to add roles before assigning any role to User. Run following SQL insert statements:

INSERT INTO roles(name) VALUES('ROLE_USER');
INSERT INTO roles(name) VALUES('ROLE_MODERATOR');
INSERT INTO roles(name) VALUES('ROLE_ADMIN');

POST - localhost:8080/api/auth/signup

{
    "username": "john doe",
    "email": "john.doe@gmail.com",
    "password": "12345678",
    "role": ["user"]
}

Should see logs similar to

Registering Agent: 0, Name: DTA
Registering Agent: 1, Name: PRA
Received user information for john doe
