No Database Operations Found: What Writing a Spring Boot Analyzer Taught Me About Spring

Thu, 03 Sep 2026 06:26:00 +0000

I spent months building a static analyzer that answers one question about a Spring Boot codebase: if I change this endpoint, what does the change reach?

Every serious bug I found in it had the same shape.

Not a wrong edge in a graph. Not a missing feature. A confident absence — the tool stating, definitively, that an endpoint touched no database, opened no transaction, published no message, when it did all three.
