Content Types

See equivalent in the Reactive stack

You can configure how Spring MVC determines the requested media types from the request (for example, Accept header, URL path extension, query parameter, and others).

By default, only the Accept header is checked.

If you must use URL-based content type resolution, consider using the query parameter strategy over path extensions. See Suffix Match and Suffix Match and RFD for more details.

You can customize requested content type resolution, as the following example shows:

  • Java

  • Kotlin

  • Xml

@Configuration
public class WebConfiguration implements WebMvcConfigurer {

	@Override
	public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
		configurer.mediaType("json", MediaType.APPLICATION_JSON);
		configurer.mediaType("xml", MediaType.APPLICATION_XML);
	}
}
@Configuration
class WebConfiguration : WebMvcConfigurer {

	override fun configureContentNegotiation(configurer: ContentNegotiationConfigurer) {
		configurer.mediaType("json", MediaType.APPLICATION_JSON)
		configurer.mediaType("xml", MediaType.APPLICATION_XML)
	}
}
<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager"/>

<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="mediaTypes">
	<value>
		json=application/json
		xml=application/xml
	</value>
</property>
</bean>
