Temporal with Spring Boot in Practice

The practical Temporal guide for Spring Boot teams

Temporal is a leading workflow orchestration platform for building long-running, failure-resilient applications. Companies such as Netflix and Stripe use it to build workflows that survive crashes, scale automatically, and run for hours, days, or months. But most Temporal content focuses on concepts and Go examples - leaving Java and Spring Boot teams to figure out integration on their own.

Temporal with Spring Boot in Practice fills that gap. This is the implementation guide for Java teams who need to wire Temporal into their Spring Boot applications and ship it to production.

• How to bootstrap Temporal in a Spring Boot 3.x application with proper auto-configuration
• How to design workflow interfaces, activity boundaries, and worker topology
• How to implement saga orchestration for multi-service transactions with compensation logic
• How to build human-in-the-loop approval flows with signals and queries
• How to test Temporal workflows with JUnit 5 and TestWorkflowEnvironment
• How to add observability with Spring Boot Actuator, structured logging, and distributed tracing
• How to version workflows safely and evolve them without breaking running executions
• How to migrate existing scheduled jobs and stateful logic to Temporal
• How to deploy to Temporal Cloud and Kubernetes
• How to use Temporal for durable AI agent workflows

Senior Java developers, Spring Boot teams adopting Temporal, and architects modernizing monolith workflows. You should know Spring Boot well - this book teaches you Temporal, not Spring.

Every chapter builds on a single e-commerce order fulfillment reference application. You'll see the same system grow from a simple workflow to a production-grade, multi-service orchestration platform. The book is 30% concept and 70% implementation - code, configuration, testing, and deployment.

This book complements Temporal.io In Practice (architecture and concepts) and Spring Boot Microservices in Practice (microservice patterns). Together, they form a complete toolkit for building modern distributed Java systems.
