Add Tweet Entity and Related Functionality

Overview

This pull request introduces a new Tweet entity along with the necessary components to support tweet creation. It also includes Docker configuration updates and CI implementation with GitHub Actions.

Key Changes

New Tweet Entity

• Added the Tweet domain model with associated properties:
  • id (String)
  • userId (String)
  • content (String) - limited to 280 characters
  • createdAt (Date)
  • likeCount (long)
• Created MongoDB document model (TweetDocument)
• Implemented MapStruct mappers for entity-domain conversions

New Tweet Endpoints

Create Tweet Endpoint

Request:

curl -X POST http://localhost:8090/api/tweets \
  -H "Content-Type: application/json" \
  -d '{
    "userId": "user123",
    "content": "This is my first tweet!"
  }'

Response Schema:

{
  "id": "string",
  "userId": "string",
  "content": "string",
  "createdAt": "date-time",
  "likeCount": 0
}

Status Codes:

• 201 Created - Tweet successfully created
• 422 Unprocessable Entity - Validation error (e.g., content exceeds 280 characters)
• 404 Not Found - User ID not found

Docker Setup

• Updated Dockerfile with optimizations:
  • Multi-stage build for smaller final image
  • Proper handling of line ending issues (CRLF to LF conversion)
  • Fixed permissions on gradlew script
• Enhanced docker-compose.yml:
  • Configured MongoDB initialization with proper user permissions
  • Added environment variables for connection details
  • Set up volume mounts for data persistence
  • Configured proper container dependencies and restart policies

CI/CD Integration

• Added GitHub Actions workflow for Java CI with Gradle
• Implemented build pipeline with the following steps:
  • JDK 17 setup
  • Gradle build configuration
  • Dependencies caching for faster builds
  • Test execution with reporting

Dependencies

• MongoDB for tweet data storage
• MapStruct for object mapping
• Spring Boot validation for request validation

Testing

• Added unit tests for the Tweet entity and related components
• Created integration tests for the TweetController endpoints
• Verified Docker setup works correctly

Deployment

The service can be deployed using Docker Compose:

docker-compose up -d
