getReadableMediaTypes
List<MediaType> getReadableMediaTypes()
Return theMediaType
's that this reader supports.
canRead
boolean canRead(ResolvableType elementType, @Nullable MediaType mediaType)
Whether the given object type is supported by this reader.- 参数:
elementType
- the type of object to checkmediaType
- the media type for the read (possiblynull
)- 返回:
true
if readable,false
otherwise
read
reactor.core.publisher.Flux<T> read(ResolvableType elementType, ReactiveHttpInputMessage message, Map<String,Object> hints)
Read from the input message and encode to a stream of objects.- 参数:
elementType
- the type of objects in the stream which must have been previously checked viacanRead(ResolvableType, MediaType)
message
- the message to read fromhints
- additional information about how to read and decode the input- 返回:
- the decoded stream of elements
readMono
reactor.core.publisher.Mono<T> readMono(ResolvableType elementType, ReactiveHttpInputMessage message, Map<String,Object> hints)
Read from the input message and encode to a single object.- 参数:
elementType
