HttpMediaTypeNotAcceptableException after upgrading to Spring 3.2

Question

After upgrading my Spring MVC application to Spring 3.2 I\'m getting the following exception when accessing some of my URLs:

org.springframework.web.HttpMediaTyp

You need to add a proper MessageConverter to your configuration, along with one you might already have for Jackson.

e.g. in your subclass of WebMvcConfigurerAdapter:

@Override
public void configureMessageConverters(final List> converters) {
    converters.add(new StringHttpMessageConverter());
}

When you still keep the favorPathExtension option turned on, you won't require a produces parameter as well, your controller will return application/javascript.

The hints in Aleksanders answer actually did not help me getting rid of the 406 when I had the same problem.
