How to use ContentNegotiationStrategy in Spring MVC3.2
Hi together,
I used to config ContentNegotiatingViewResolver in Spring3.1 with inject mediaTypes as
Code:
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="mediaTypes">
<map>
<entry key="json" value="application/json"/>
</map>
</property>
<property name="defaultViews">
<list>
<bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView" />
</list>
</property>
</bean>
but in spring3.2 setMediaTypes is deprecated in ContentNegotiatingViewResolver and suggest to use setContentNegotiationManager.
Furthermore, if I use mediaTypes in spring3.2 it will thorw a ClassCastException in its parent class MappingMediaTypeFileExtensionResolver
Code:
java.lang.ClassCastException: java.lang.String cannot be cast to org.springframework.http.MediaType
at org.springframework.web.accept.MappingMediaTypeFileExtensionResolver.<init>(MappingMediaTypeFileExtensionResolver.java:56)
at org.springframework.web.accept.AbstractMappingContentNegotiationStrategy.<init>(AbstractMappingContentNegotiationStrategy.java:42)
at org.springframework.web.accept.PathExtensionContentNegotiationStrategy.<init>(PathExtensionContentNegotiationStrategy.java:74)

at org.springframework.web.servlet.view.ContentNegotiatingViewResolver.afterPropertiesSet(ContentNegotiatingViewResolver.java:270)
I don't know how to declare a contentNegotiationManager and inject into ContentNegotiatingViewResolver or how to use ContentNegotiationStrategy in Spring MVC3.2
Any ideas?
Thanks!
