Method Detail

getCharset

public Charset getCharset()

Return the configured charset for part headers.

setCharset

public void setCharset(Charset charset)

Set the character set to use for part headers such as "Content-Disposition" (and its filename parameter).

By default this is set to "UTF-8". If changed from this default, the "Content-Type" header will have a "charset" parameter that specifies the character set used.

getWritableMediaTypes

public List<MediaType> getWritableMediaTypes()

canWrite

public boolean canWrite(ResolvableType elementType,
                        @Nullable
                        MediaType mediaType)

generateMultipartBoundary

protected byte[] generateMultipartBoundary()

Generate a multipart boundary.

By default delegates to MimeTypeUtils.generateMultipartBoundary().

getMultipartMediaType

protected MediaType getMultipartMediaType(@Nullable
                                          MediaType mediaType,
                                          byte[] boundary)

Prepare the MediaType to use by adding "boundary" and "charset" parameters to the given mediaType or "multipart/form-data" otherwise by default.

generateBoundaryLine

protected reactor.core.publisher.Mono<DataBuffer> generateBoundaryLine(byte[] boundary,
                                                                       DataBufferFactory bufferFactory)

generateNewLine

protected reactor.core.publisher.Mono<DataBuffer> generateNewLine(DataBufferFactory bufferFactory)

generateLastLine

protected reactor.core.publisher.Mono<DataBuffer> generateLastLine(byte[] boundary,
                                                                   DataBufferFactory bufferFactory)

generatePartHeaders

protected reactor.core.publisher.Mono<DataBuffer> generatePartHeaders(HttpHeaders headers,
                                                                      DataBufferFactory bufferFactory)
