> Setting the HTTP Content-Type request header to either application/json or
> application/json;charset=UTF-8 does not get handled correctly by the
> DefaultContentTypeHandlerManager. At line 91 (v2.3.8) in
> DefaultContentTypeHandlerManager, the content type is stripped of everything
> after and including the semi-colon (i.e., application/json;charset=UTF-8
> becomes application/json). Line 91-93:
> int index = contentType.indexOf(';');
> if( index != -1)
> contentType = contentType.substring(0,index).trim();
> Unfortunately, the JsonLibHandler getContentType() method returns
> "application/json;charset=ISO-8859-1" and because the charset was stripped,
> the JsonLibHandler is not correctly chosen.
> This issue is can potentially be mitigated by additionally setting the
> extension to .json but it would be nice to rely solely on the Content-Type
> header.
> I see the value of stripping the header down to the basic type so it's likely
> that the handlersByContentType Map will need to be interrogated twice.
> Something like this:
> String contentType = req.getContentType();
> if (contentType != null) {
> handler = handlersByContentType.get(contentType);
> if ( handler == null ) {
> int index = contentType.indexOf(';');
> if( index != -1)
> contentType =
> contentType.substring(0,index).trim();
> handler =
> handlersByContentType.get(contentType);
> }
> }
