MessageBodyReader/Writer for MultivaluedMap

["Penmatsa, Vinay" <vi...@sap.com>]

>From documentation in http://cxf.apache.org/docs/jax-rs-basics.html#JAX-RSBasics-MessageBodyProviders:

"By default, CXF supports String, byte[], InputStream, Reader, File, JAXP Source, JAX-RS StreamingOutput, JAXB-annotated types with application/xml, text/xml and application/json formats as well as JAXBElement (see below). JAX-RS MultivaluedMap is also supported for form contents. 
See also the "Support for data bindings" section below."

I couldn't find a MessageBodyReader/Writer implementation for MultivaluedMap in CXF. How could I use this type?
In general, if I want to use a Map<String,String> in a REST POST, should I write readers/writers for the Map type or does CXF provide anything by default?

Thanks,
Vinay

org.apache.cxf.jaxrs.provider.FormEncodingProvider manages 
MultivaluedMap, it is enabled by default

Map<String, String> is not equivalent to MultivaluedMap<String, String>, 
the latter is actually Map<String, List<String>>.

So yes, if you need to handle Map<String, String>, then add a provider 
for it

Not sure if this answers your question, but here: 
https://github.com/gmazza/jersey-samples-on-cxf/blob/master/simple-servlet/src/main/java/com/sun/jersey/samples/servlet/resources/ResourceBean3.java#L130 
(line 130-160) shows ways to work with MultivaluedMap within a REST 
resource (at least with a @GET).   A custom MessageBodyReader/Writer 
wasn't needed in that case.

This was for the "simple-servlet" example listed here:

HTH,
Glen
