MessageBodyReader
type
parameter gives the
class of the instance that should be produced, the genericType
parameter
gives the java.lang.reflect.Type
of the instance
that should be produced.
E.g. if the instance to be produced is List<String>
, the type
parameter
will be java.util.List
and the genericType
parameter will be
java.lang.reflect.ParameterizedType

- the type of instance to be produced. E.g. if the
message body is to be converted into a method parameter, this will be
the formal type of the method parameter as returned by
Method.getGenericParameterTypes
.annotations
- an array of the annotations on the declaration of the
artifact that will be initialized with the produced instance. E.g. if the
message body is to be converted into a method parameter, this will be
the annotations on that parameter returned by

- the media type of the HTTP entity, if one is not
specified in the request then application/octet-stream

used.true

MessageBodyReader
InputStream
.
In case the entity input stream is empty, the reader is expected to either return a
Java representation of a zero-length entity or throw a NoContentException
in case no zero-length entity representation is defined for the supported Java type.
A NoContentException
, if thrown by a message body reader while reading a server
request entity, is automatically translated by JAX-RS server runtime into a BadRequestException
wrapping the original NoContentException
and rethrown for a standard processing by
the registered exception mappers
.

and the reader is not able to produce a Java representation for

be thrown.WebApplicationException

MessageBodyWriter
writeTo
to ascertain the length in bytes of
the serialized form of t
. A non-negative return value has been used in a HTTP
Content-Length
header.
As of JAX-RS 2.0, the method has been deprecated and the value returned by the method is ignored
by a JAX-RS runtime. All MessageBodyWriter
implementations are advised to return -1
from the method. Responsibility to compute the actual Content-Length
header value has been
delegated to JAX-RS runtime.
