## What it is
A hands-on educational Java project that builds a distributed microservice system from scratch using the SSM stack (Spring, SpringMVC, MyBatis) with Dubbo, Kafka, Redis, Lucene, and Shiro. It accompanies a blog series covering practical techniques like seckill (flash-sale) architecture, MQ usage, and locking strategies.

## Use cases
- learn how to build a distributed microservice architecture with Dubbo
- study a flash-sale seckill system implementation
- see how Kafka consumers handle order processing
- understand optimistic and pessimistic locking in practice
- learn Maven multi-module project structuring for internet-scale apps
- explore exposing Dubbo services over HTTP

## When to choose
- you want a worked example of SSM + Dubbo microservices to study
- you are learning distributed system patterns like seckill and message queues in Java
- you follow the author's blog series and want the accompanying code

## When to avoid
- you need a production-ready microservice framework or scaffold
- you want actively maintained code with recent releases
- your stack is not Java/Spring-based
- you need modern alternatives like Spring Cloud or Kubernetes-native services
