A curated collection of Java ecosystem study modules and runnable samples covering Spring Boot, Redis, Dubbo, RocketMQ, Kafka, Elasticsearch, Netty, ZooKeeper, and related middleware, plus newer Java x AI modules (LangChain4j, MCP Server). It serves as a hands-on reference for learning distributed systems and microservice technologies in Java.

Use cases

• learn spring boot with runnable examples
• study dubbo rpc and microservices architecture
• understand rocketmq and kafka messaging patterns
• explore redis caching and distributed locks
• practice elasticsearch client usage
• learn netty nio programming
• try langchain4j and mcp server in java
• reference for sharding and distributed scheduling

When to choose

• you want curated, working sample code for mainstream Java middleware
• you are studying distributed systems concepts like RPC, message queues, and caching
• you need reference examples for Spring Boot 3.x and Java 17+
• you want to explore Java AI engineering with LangChain4j and MCP

When to avoid

• you need a production-ready framework or library to depend on
• you want a single cohesive application rather than independent demo modules
• you work outside the JVM ecosystem
