用 Java 5 分钟写一个 MCP Server：我开源了 MCP Java SDK

A new open-source MCP Java SDK has been released to help Java developers build Model Context Protocol servers efficiently. The project simplifies exposing tools, resources, and prompts to AI Agents like Claude and Cursor. It features a core SDK supporting stdio and SSE transport, annotation-based tool registration, and a Spring Boot starter. Available on Maven Central, the SDK includes ready-to-use MySQL and Redis servers, allowing developers to create custom MCP servers in five minutes.
