Spring MVC Disable request time-out for specific endpoint

Yes. Instead of changing the global async timeout, you can set the timeout per request. WebAsyncTask or DeferredResult. This lets you keep the default timeout for other endpoints.

For your case StreamingResponseBody, wrap it in WebAsyncTask and specify a custom timeout.

Example:

@PostMapping(value = "/.../endpoint", produces = "application/zip") public WebAsyncTask<ResponseEntity<StreamingResponseBody>> renderImages(...) { StreamingResponseBody stream = outputStream -> { // rendering + streaming logic }; ResponseEntity<StreamingResponseBody> response = ResponseEntity.ok().body(stream); // disable timeout for this endpoint (-1) or set custom timeout in ms return new WebAsyncTask<>(-1, () -> response); }

You could also set a longer timeout instead of disabling it:

return new WebAsyncTask<>(600_000, () -> response); // 10 minutes
