Class UriConnegFilter

  • All Implemented Interfaces:
    ContainerRequestFilter

    @PreMatching
    @Priority(3000)
    public final 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.

      • UriConnegFilter

        public UriConnegFilter​(@Context
                               Configuration rc)
        Create a filter that reads the configuration (media type and language mappings) from the provided ResourceConfig instance. This constructor will be called by the Jersey runtime when the filter class is returned from Application.getClasses(). The ResourceConfig instance will get auto-injected.
        Parameters:
        rc - ResourceConfig instance that holds the configuration for the filter.
      • UriConnegFilter

        public UriConnegFilter​(Map<String,​MediaType> mediaTypeMappings,
                               Map<String,​String> languageMappings)
        Create a filter with suffix to media type mappings and suffix to language mappings.
        Parameters:
        mediaTypeMappings - the suffix to media type mappings.
        languageMappings - the suffix to language mappings.

      • filter

        public void filter​(ContainerRequestContext rc)
                    throws IOException
        Description copied from interface: ContainerRequestFilter
        Filter method called before a request has been dispatched to a resource.

        Filters in the filter chain are ordered according to their jakarta.annotation.Priority class-level annotation value. If a request filter produces a response by calling ContainerRequestContext.abortWith(jakarta.ws.rs.core.Response) method, the execution of the (either pre-match or post-match) request filter chain is stopped and the response is passed to the corresponding response filter chain (either pre-match or post-match). For example, a pre-match caching filter may produce a response in this way, which would effectively skip any post-match request filters as well as post-match response filters. Note however that a responses produced in this manner would still be processed by the pre-match response filter chain.

        Specified by:
        filter in interface ContainerRequestFilter
        Parameters:
        rc - request context.
        Throws:
        IOException - if an I/O exception occurs.
