This guide explains how to create a modular, plugin‑style service framework in Java using the Service Provider Interface (SPI), covering project structure, interface definition, implementation jars, META‑INF configuration, and a client example that loads multiple time‑service implementations at runtime.
The article provides a comprehensive overview of ares-client, detailing its functional positioning, overall architecture, SPI and Base API design, common and special instrumentation, dump and replay mechanisms, request association and filtering strategies, as well as performance optimizations and future enhancements for backend testing integration.
Dubbo, an extensible Java RPC framework, evolves from simple single‑app setups to distributed service and dynamic resource governance architectures, offering RESTful calls, high‑performance serialization, flexible protocols, various clustering strategies, load‑balancing options, and a modular SPI‑based core, all detailed with diagrams and code snippets.
