org.springframework.web.reactive.result.method.annotation.ResponseBodyResultHandler

All Implemented Interfaces:

org.springframework.core.Ordered, HandlerResultHandler

public class ResponseBodyResultHandler
extends AbstractMessageWriterResultHandler
implements HandlerResultHandler

HandlerResultHandler that handles return values from methods annotated with @ResponseBody writing to the body of the request or response with an HttpMessageWriter.

By default the order for this result handler is set to 100. As it detects the presence of @ResponseBody it should be ordered after result handlers that look for a specific return type. Note however that this handler does recognize and explicitly ignores the ResponseEntity return type.

Since:

5.0
