Empower your Spring Applications with Python Features on GraalVM
summary
Shows how GraalVM runs Python side‑by‑side with Spring Boot by installing GraalVM CE Java 17, using GraalPy + numpy via gu/qi inside a Dockerfile, creating a polyglot Context with forceImportSite and pythonPath, and injecting a Python class as implementation of a Java interface so the recommender runs as a Spring bean. Demonstration builds a recommender that computes Euclidean distances with numpy in one line, tests via Spring integration tests, and notes slower startup and no native‑image support yet.
