Class UriConnegFilter

java.lang.Object

org.glassfish.jersey.server.filter.UriConnegFilter

All Implemented Interfaces:

ContainerRequestFilter

@PreMatching
public class UriConnegFilter
extends Object
implements ContainerRequestFilter

A URI-based content negotiation filter mapping a dot-declared suffix in URI to media type that is the value of the Accept header or a language that is the value of the Accept-Language header.

This filter may be used when the acceptable media type and acceptable language need to be declared in the URI.

This class may be extended to declare the mappings and the extending class, foo.MyUriConnegFilter say, can be registered as a container request filter.

If a suffix of "atom" is registered with a media type of "application/atom+xml" then a GET request of:

GET /resource.atom

is transformed to:

GET /resource
Accept: application/atom+xml

Any existing "Accept" header value will be replaced.

If a suffix of "english" is registered with a language of "en" then a GET request of:

GET /resource.english

is transformed to:

GET /resource
Accept-Language: en

Any existing "Accept-Language"header value will be replaced.

The media type mappings are processed before the language type mappings.
