## Health v2 (maintenance only)
Score: 69/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 81, release rhythm 35, longevity 100
- inputs: {"age_days": 2437, "days_push": 119, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

Stars 1031, forks 588 (observed 2026-08-28T04:03:17.956395+00:00)

## What it is
Sample Java/Spring Boot code accompanying the Geek Time 'DDD in Practice' course, demonstrating a leave-approval microservice designed with Domain-Driven Design. It illustrates aggregates, repositories, domain events, layered architecture, and inter-service communication with PostgreSQL persistence.

## Use cases
- learn domain-driven design with a real Java codebase
- see how to structure a DDD microservice with Spring Boot
- understand aggregate roots, entities, and value objects in practice
- study domain event persistence and publishing patterns
- learn DDD layered architecture (domain, application, infrastructure, interface)
- reference example for splitting a monolith into microservices
- see DTO/DO/PO object conversion across layers

## When to choose
- you are learning DDD and want a worked Java example
- you follow the Geek Time DDD course and need its companion code
- you want a reference for repository, factory, and domain event patterns in Spring Boot

## When to avoid
- you need production-ready leave/attendance software
- you need a maintained library with a license and active support
- you work outside the Java/Spring ecosystem

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: web-framework, database, middleware
- domain: developer-tools, backend, tutorials, apis
- platform: jvm, self-hosted
- tags: ddd, domain-driven-design, sample-code, spring-boot, postgresql, microservices, geektime, leave-management, event-storming, chinese, docker
