HTTP Streaming Directly to the OutputStream [SPR-12831]

[spring-projects-issues]

Marcel Overdijk opened SPR-12831 and commented

Provide a way to returning a ResponseEntity containing a streaming output stream.
This similar to Jersey's https://docs.oracle.com/javaee/6/api/javax/ws/rs/core/StreamingOutput.html

This is useful for large files to be downloaded.

As part of work for #16826 we've added support for returning ResponseEntity with an SseEmitter as the body as well as the more general ResponseBodyEmitter, which applies an HttpMessageConverter each time an object is emitted. I'm wondering if you have seen that?

The new return value type is called StreamingResponseBody.
