Unable to configure MappingJacksonHttpMessageConverter created by AnnotationDrivenBeanDefinitionParser [SPR-7924]

[spring-projects-issues]

Joern Huxhorn opened SPR-7924 and commented

org.springframework.web.servlet.config.AnnotationDrivenBeanDefinitionParser
executes
messageConverters.add(createConverterBeanDefinition(MappingJacksonHttpMessageConverter.class, source));
at line 187 in spring-webmvc-3.0.5.RELEASE

There is no way that I'm aware of to configure the created MappingJacksonHttpMessageConverter instance.

I'd need to set the ObjectMapper of this instance so it's able to use my MixIn configuration (special handling of certain data types defined using serializationConfig.addMixInAnnotations or deserializationConfig.addMixInAnnotations) and other ObjectMapper configuration.

Otherwise, serializing e.g. a java.awt.Dimension is guaranteed to explode.

Is there any way to configure it that I'm missing? I searched quite extensive but couldn't find anything so far. Any workaround would be highly appreciated, even a hacky, temporary one...

This issue may be related to #11397.

Support for configuring message converters has been added to the MVC namespace and will be available in 3.1 M1.

Every issue I could find so far was referring to the ConversionService and I'm not sure if my requirement of being able to configure the ObjectMapper is met, yet.

Could you please give me a pointer to more some more infos, e.g. the issue this issue duplicates, some docs about the upcoming MVC namespace changes, pointer to the related source, a possible workaround for the problem at hand?

The related forum post is http://forum.springsource.org/showthread.php?p=342898

I'll reopen this bug simply because I'm not sure if you'd get notified of my comment if I don't.
Thanks for the fast response.

Yes, I forgot to include a reference to the ticket indeed, my apologies! See this comment under #12161 for example configuration.

This looks quite good indeed!
Any idea about a release date of the milestone? A rough guess would be enough...

You can build against 3.1.0.BUILD-SNAPSHOT already. As for the milestone I don't have any dates but I can recommend the webinar on Spring 3.1 next week (see http://www.springsource.com/newsevents/webinars).
