  指定者:

  write 在接口中 HttpMessageWriter<T>

  参数:

  inputStream - the objects to write

  elementType - the type of objects in the stream which must have been previously checked via HttpMessageWriter.canWrite(ResolvableType, MediaType)

  mediaType - the content type for the write (possibly null to indicate that the default content type of the writer must be used)

  message - the message to write to

  hints - additional information about how to encode and write

  返回:

  indicates completion or error

• write

  public reactor.core.publisher.Mono<Void> write​(org.reactivestreams.Publisher<? extends T> inputStream,

  从接口复制的说明: HttpMessageWriter
  Server-side only alternative to HttpMessageWriter.write(Publisher, ResolvableType, MediaType, ReactiveHttpOutputMessage, Map) with additional context available.

  指定者:

  write 在接口中 HttpMessageWriter<T>

  actualType - the actual return type of the method that returned the value; for annotated controllers, the MethodParameter can be accessed via ResolvableType.getSource().

  elementType - the type of Objects in the input stream

  mediaType - the content type to use (possibly null indicating the default content type of the writer should be used)

  request - the current request

  response - the current response

  返回:

  a Mono that indicates completion of writing or error

• getWriteHints

  protected Map<String,​Object> getWriteHints​(ResolvableType streamType,
                                                   ResolvableType elementType,

  Get additional hints for encoding for example based on the server request or annotations from controller method parameters. By default, delegate to the encoder if it is an instance of HttpMessageEncoder.
