🎯 Overview

This microservice is responsible for tracking all work hours logged by employees against specific services and projects. It provides comprehensive time tracking capabilities with proper authorization, validation, and analytics.

Assigned Team: Dhanuja, Mahesh

🎯 Key Responsibilities

✅ Allow employees to create, read, update, and delete their time log entries
✅ Associate each log with specific serviceId or projectId
✅ Provide summary endpoints for employee productivity analysis
✅ Support daily and weekly time aggregations
✅ Enforce ownership rules (employees can only modify their own logs)
✅ Generate statistics and analytics for work distribution
✅ Query time logs by service, project, employee, or date range

ℹ️ Service Information

Local Port: 8085
Gateway Path: /api/v1/time-logs
Swagger UI: http://localhost:8085/swagger-ui/index.html
API Docs: http://localhost:8085/v3/api-docs
Health Check: http://localhost:8085/actuator/health

🚀 Quick Start

Prerequisites

✅ Java 17+
✅ Maven 3.6+
✅ PostgreSQL 15+

1. Database Setup

CREATE DATABASE techtorque_timelogs;
CREATE USER techtorque WITH PASSWORD 'techtorque123';
GRANT ALL PRIVILEGES ON DATABASE techtorque_timelogs TO techtorque;

2. Run Locally

# Navigate to service directory
cd Time_Logging_Service/time-logging-service

# Run with Maven
mvn spring-boot:run

# Or build and run JAR
mvn package
java -jar target/time-logging-service-0.0.1-SNAPSHOT.jar

3. Using Docker Compose

This service is designed to be run as part of the main docker-compose setup from the project's root directory.

# From the root of the TechTorque-2025 project
docker-compose up --build time-logging-service

# Or run all services
docker-compose up

4. Verify Running

# Check health
curl http://localhost:8085/actuator/health

# Expected: {"status":"UP"}

🔑 Authentication

All endpoints require JWT authentication via the API Gateway. Include these headers:

Authorization: Bearer <jwt-token>
X-User-Subject: <employee-uuid>
X-User-Role: <user-role>

For local development with security disabled:

export SECURITY_ENABLED=false
mvn spring-boot:run

🔒 Security & Authorization

Role-Based Access Control

EMPLOYEE: Can create, view, update, delete own time logs
ADMIN: Can view all time logs (read-only)
CUSTOMER: Can view time logs for their services/projects

Ownership Validation

Employees can only modify their own logs
Authorization checks in service layer
Proper exception handling for unauthorized access

🧪 Testing

Run Tests

mvn test

Test with cURL

# Create time log
curl -X POST http://localhost:8085/time-logs \
  -H "Content-Type: application/json" \
  -H "X-User-Subject: 00000000-0000-0000-0000-000000000003" \
  -d '{
    "serviceId": "SRV-001",
    "hours": 3.5,
    "date": "2025-11-05",
    "description": "Oil change",
    "workType": "Maintenance"
  }'

Test Data (from DataSeeder)

Employee IDs:

00000000-0000-0000-0000-000000000003  (Employee 1)
00000000-0000-0000-0000-000000000004  (Employee 2)
00000000-0000-0000-0000-000000000005  (Employee 3)

The service automatically seeds 30 time logs (10 per employee) in development mode.
