Spring MVC ContentNegotiation Content Negotiation

 

SpringMVC 's content negotiation supports three ways:

 

1. Use suffixes, such as .json and .xml suffixes.

2. Use the Accept header

3. Specify through the query parameter, such as the ?format=xml parameter, indicating that data in XML format is required to be returned ( the default parameter name is format, which can be modified. )

 

 

If some or all of the above methods are enabled at the same time, the parsing order is suffix, parameter, and Accept header .

 

	<!-- Make this available across all of Spring MVC -->
	<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager" />
	 
	<!-- Total customization - see below for explanation. -->
	<bean id="contentNegotiationManager"
	class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
	<property name="favorPathExtension" value="true" />
	<property name="favorParameter" value="false" />
	<property name="parameterName" value="format" />
	<property name="ignoreAcceptHeader" value="false"/>
	<property name="useJaf" value="false"/>
	<property name="defaultContentType" value="text/html" />
	 
	<property name="mediaTypes">
	<map>
	<entry key="json" value="application/json" />
	<entry key="xml" value="application/xml" />
	</map>
	</property>
	</bean>
