org.springframework.web.accept.AbstractMappingContentNegotiationStrategy

org.springframework.web.accept.ParameterContentNegotiationStrategy

All Implemented Interfaces:

ContentNegotiationStrategy, MediaTypeFileExtensionResolver

public class ParameterContentNegotiationStrategy
extends AbstractMappingContentNegotiationStrategy

Strategy that resolves the requested content type from a query parameter. The default query parameter name is "format".

You can register static mappings between keys (i.e. the expected value of the query parameter) and MediaType's via MappingMediaTypeFileExtensionResolver.addMapping(String, MediaType). As of 5.0 this strategy also supports dynamic lookups of keys via MediaTypeFactory.getMediaType(org.springframework.core.io.Resource).

Since:

3.2
