Spring Boot 2.0 Web Applications
summary
Spring Boot 2 adds Spring Framework 5 and WebFlux + Project Reactor to let apps handle many concurrent clients without blocking. Demos build a sensor aggregator that saves ten-second telemetry to MongoDB and exposes a single WebClient and shared Flux so many subscribers use one backend request; the browser graph updates via SSE + Thymeleaf data-driven mode every 10s. Spring Data supports reactive Mongo/Cassandra drivers and infinite streams, actuator and security are reworked, metrics move to Micrometer. One demo hits a small typo but the core pipelines work.
