Examples with MediaType org.springframework.http.MediaType used on opensource projects

Example 21 with MediaType

use of org.springframework.http.MediaType in project spring-framework by spring-projects.

the class ContentNegotiationManagerFactoryBean method setMediaTypes.

/**
	 * Add a mapping from a key, extracted from a path extension or a query
	 * parameter, to a MediaType. This is required in order for the parameter
	 * strategy to work. Any extensions explicitly registered here are also
	 * whitelisted for the purpose of Reflected File Download attack detection
	 * (see Spring Framework reference documentation for more details on RFD
	 * attack protection).
	 * <p>The path extension strategy will also try to use
	 * {@link ServletContext#getMimeType} and JAF (if present) to resolve path
	 * extensions. To change this behavior see the {@link #useJaf} property.
	 * @param mediaTypes media type mappings
	 * @see #addMediaType(String, MediaType)
	 * @see #addMediaTypes(Map)

Example 23 with MediaType

use of org.springframework.http.MediaType in project spring-framework by spring-projects.
