MinIO File Service

This project is a Java Spring Boot application that integrates MinIO, an open-source object storage service. The application provides functionalities for managing file uploads, storage, and retrieval, using MinIO as a storage backend.

Features

• File Upload: Allows users to upload files to the MinIO server.
• File Download: Enables downloading of stored files.
• File Metadata Management: Keeps track of file metadata through a database.
• Error Handling: Custom exceptions are used to provide meaningful error messages.

Technologies Used

• Java 17: Core programming language.
• Spring Boot: Framework for building the RESTful API.
• MinIO: Object storage system used for storing uploaded files.
• Maven: Dependency management.
• H2 Database: Embedded database for storing file metadata (can be replaced with other databases).

Project Structure

• config: Contains configuration classes including MinIO connection properties.
• controller: Handles incoming HTTP requests related to file operations.
• domain: Represents entities, such as FileEntity, used to store file-related data.
• repo: Manages database operations for storing and retrieving file metadata.
• service: Contains services for interacting with MinIO and managing files.
• utils: Utility classes for file operations.

Getting Started

Prerequisites

• Java 17 or higher
• Maven for building the project
• MinIO Server running locally or accessible remotely

Installation

1. Clone the repository

   git clone <repository-url>
   cd minio-file-service

2. Set up MinIO configuration

   • Update the .env file or application.properties with your MinIO credentials (e.g., access key, secret key, and endpoint).

3. Build the project

   ./mvnw clean install

4. Run the application

   ./mvnw spring-boot:run

Usage

• Upload a File: Use an API client like Postman to send a POST request to /api/files/upload with the file in the request body.
• Download a File: Send a GET request to /api/files/download/{fileId} to retrieve a file.

Configuration

• The application properties for connecting to MinIO are defined in the application.properties file.
• You can modify the following settings:
  • minio.url: The URL of the MinIO server.
  • minio.access-key: Your MinIO access key.
  • minio.secret-key: Your MinIO secret key.

Error Handling

The application uses custom exceptions to handle errors, such as FileException and InvalidRequestException. These exceptions ensure meaningful messages are returned to users.
