Activity Log Service

Overview

The Activity Log Service is a microservice responsible for logging user activities in the Recipe Sharing Platform. It receives event-based logs from the main application via a Feign client and stores them in a separate database.

Features

• Exposes REST API endpoints to store and retrieve activity logs

• Uses a dedicated database for logging

Technologies Used

• Spring Boot (REST API)

• Spring Data JPA (Persistence layer)

• MySQL (Database)

• Lombok (Code simplification)

• JUnit (Testing)

API Endpoints

Setup & Run Locally

1. Clone the repository:

git clone https://github.com/tsekovTriesCoding/activity-log-service.git
cd activity-log-service

Configure the database: Update application.yml:

spring:
datasource:
url: jdbc:mysql://localhost:3306/activity_log_db
username: root
password: yourpassword

Build and run the application:

mvn clean install
mvn spring-boot:run

Access the API at http://localhost:8081/api/v1/activity-log

Run with Docker

1. Set up environment variables Create a .env file in the root of the project with the following content:

MYSQL_ROOT_PASSWORD=yourpass
MYSQL_DATABASE=db_name
MYSQL_USER=activityuser
MYSQL_PASSWORD=activitypass

• Feel free to adjust the values to match your needs.

2. Build and run the containers From the root of the project directory, run: docker-compose up --build

This will:

• Start a MySQL database container on port 3308.
• Build and run the Activity Log Service container on port 8081.

3. Access the API Once the services are up, the Activity Log API will be available at:

http://localhost:8081/api/v1/activity-log
