Lesson 2 Complete Solution

This folder contains the complete solution for Lesson 2: Kotlin + Spring Boot + Temporal Setup.

What's Included

• TemporalStarterApplication.kt - Spring Boot main class
• config/TemporalConfig.kt - Complete Temporal configuration with:
  • Connection to local Temporal server
  • Workflow client setup
  • Worker factory configuration
  • Basic worker that connects to a test queue

How It Works

1. WorkflowServiceStubs - Connects to Temporal server (localhost:7233 by default)
2. WorkflowClient - Provides the interface to start workflows and interact with Temporal
3. WorkerFactory - Creates and manages workers that execute workflows and activities
4. Worker - Listens to a specific task queue for work to execute

Running This Solution

Make sure you have Temporal server running locally (see Lesson 3), then you should see output like:

✅ Temporal worker started successfully! Connected to local Temporal server.

Key Learning Points

• Temporal configuration uses Spring beans for dependency injection
• Workers must be started after configuration is complete
• Graceful shutdown ensures workers stop cleanly
• The worker factory manages multiple workers efficiently

Next Steps

In Lesson 3, we'll learn how to run Temporal server locally and see this connection in action!
