on YouTube ↗01h 22m

" summary

Spring Framework 4.2 adds concrete features for web apps: HTTP streaming with ResponseBodyEmitter and SseEmitter plus StreamingResponseBody for direct OutputStream writes, built-in Server-Sent Events formatting, and a working curl/browser demo; fine‑grained CORS via @CrossOrigin and MVC-level config (including preflight handling quirks with Spring Security); updated HTTP caching primitives via CacheControl and ResponseEntity helpers; byte‑range support for static resources; RestTemplate gains OkHttp support; WebSocket/SockJS/STOMP gets heartbeats, selectors and multi‑server user destinations, and a Java STOMP client.
