Tutorial: Wiring Spring Boot Methods into Claude Code with @McpTool

On October 29, 2026 at 12:33, a hands-on tutorial appeared on Juejin (a Chinese developer community) covering the use of Spring AI 2.0.2 with Claude Code. The article walks through a concrete setup: using the @McpTool annotation provided by Spring AI 2.0.2 to expose Spring Boot methods as MCP tools, and then connecting Claude Code to them over Streamable HTTP. Rather than stopping at a high-level description, the piece includes curl commands for self-testing the endpoint, so readers can verify the tool exposure works end to end, and it also flags several common pitfalls encountered along the way. That is the full extent of what has been reported so far. Because only a single source is available, no additional milestones, version changes, or follow-up developments can be confirmed yet. The current state of the event therefore rests on this one practical walkthrough: Spring AI 2.0.2 exposing Spring Boot methods as MCP tools via @McpTool, consumed by Claude Code through Streamable HTTP, with verification steps and known issues documented.
