How to use ResponseBodyEmitter for asynchronous processing in SpringMVC

Editor to share with you how SpringMVC uses ResponseBodyEmitter for asynchronous processing, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Use ResponseBodyEmitter for asynchronous processing

Both DeferredResult and Callable can return only one asynchronous value. If you need to return more than one object, use ResponseBodyEmitter. Each object returned is processed by HttpMessageConverter and written back to the output stream. If you want to set up more return data, such as header, status, and so on, you can return ResponseBodyEmitter as entity data for ResponseEntity.

@ RequestMapping ("/ async/responseBodyEmitter") public ResponseBodyEmitter responseBodyEmitter () {ResponseBodyEmitter responseBodyEmitter=new ResponseBodyEmitter (); Executors.newSingleThreadExecutor (). Submit (()-> {try {responseBodyEmitter.send ("demo"); responseBodyEmitter.send ("test"); responseBodyEmitter.complete ();} catch (Exception ignore) {}}); return responseBodyEmitter;} above is all the content of the article "how SpringMVC uses ResponseBodyEmitter for Asynchronous processing".
