org.springframework.http.codec.multipart.SynchronossPartHttpMessageReader

All Implemented Interfaces:

HttpMessageReader<Part>

public class SynchronossPartHttpMessageReader
extends LoggingCodecSupport
implements HttpMessageReader<Part>

HttpMessageReader for parsing "multipart/form-data" requests to a stream of Part's using the Synchronoss NIO Multipart library.

This reader can be provided to MultipartHttpMessageReader in order to aggregate all parts into a Map.

Since:

5.0

Method Detail

setMaxInMemorySize

public void setMaxInMemorySize(int byteCount)

Configure the maximum amount of memory that is allowed to use per part. When the limit is exceeded:

• file parts are written to a temporary file.
• non-file parts are rejected with DataBufferLimitException.

By default in 5.1 this is set to -1 in which case this limit is not enforced and all parts may be written to disk and are limited only by the maxDiskUsagePerPart property. In 5.2 this default value for this limit is set to 256K.

Parameters:

byteCount - the in-memory limit in bytes, or -1 for unlimited

Since:

5.1.11

getMaxInMemorySize

public int getMaxInMemorySize()

Get the configured maximum in-memory size.

Since:

5.1.11

setMaxDiskUsagePerPart

public void setMaxDiskUsagePerPart(long maxDiskUsagePerPart)

Configure the maximum amount of disk space allowed for file parts.

By default this is set to -1.

Parameters:

maxDiskUsagePerPart - the disk limit in bytes, or -1 for unlimited

Since:

5.1.11

getMaxDiskUsagePerPart

public long getMaxDiskUsagePerPart()

Get the configured maximum disk usage.

Since:

5.1.11

setMaxParts

public void setMaxParts(int maxParts)

Specify the maximum number of parts allowed in a given multipart request.

Since:

5.1.11

getMaxParts

public int getMaxParts()

Return the configured limit on the number of parts.

Since:

5.1.11

getReadableMediaTypes

public List<MediaType> getReadableMediaTypes()

Description copied from interface: HttpMessageReader

Return the MediaType's that this reader supports.

Specified by:

getReadableMediaTypes in interface HttpMessageReader<Part>

canRead

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

Description copied from interface: HttpMessageReader

Whether the given object type is supported by this reader.

Specified by:

canRead in interface HttpMessageReader<Part>

Parameters:

elementType - the type of object to check

mediaType - the media type for the read (possibly null)

Returns:

true if readable, false otherwise

read

public reactor.core.publisher.Flux<Part> read(ResolvableType elementType,
                                              ReactiveHttpInputMessage message,
                                              Map<String,Object> hints)

Description copied from interface: HttpMessageReader

Read from the input message and encode to a stream of objects.

Specified by:

read in interface HttpMessageReader<Part>

Parameters:

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

message - the message to read from

hints - additional information about how to read and decode the input

Returns:

the decoded stream of elements

readMono

public reactor.core.publisher.Mono<Part> readMono(ResolvableType elementType,
                                                  ReactiveHttpInputMessage message,
                                                  Map<String,Object> hints)

Description copied from interface: HttpMessageReader

Read from the input message and encode to a single object.

Specified by:

readMono in interface HttpMessageReader<Part>

Parameters:

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

message - the message to read from
