Spring Tools 4 - A look behind the scenes

on YouTube ↗34m

" summary

A complete rewrite of Spring Tools focuses on Spring Boot and runs as a standalone language server that works with Eclipse, VS Code, Atom and more. It uses the Language Server Protocol, reuses the JDT Java parser as a Maven dependency to parse and resolve types, extracts Spring-specific symbols, and shows Spring Boot actuators via JMX. Live hovers and code lenses display actual bean wiring from any running Java process, avoids brittle static validations, and emphasizes low-latency, nonblocking responses and independent language-server updates.
