Configure Jackson Using Spring 4 Java Config

I am using a Spring 4 MVC application. I want to configure Jackson using Java Config method, specifically to set the wrap_root_value property but I can't figure out how to do it.

Can someone please provide assistance. Thanks

Solution

  • You can create one objectMapper which extends the codehaus like -

    public class JaxbJacksonObjectMapper extends ObjectMapper {

    public JaxbJacksonObjectMapper() {
        final AnnotationIntrospector introspector = new JaxbAnnotationIntrospector();

        this.configure(org.codehaus.jackson.map.DeserializationConfig.Feature.UNWRAP_ROOT_VALUE, true);
        super.getDeserializationConfig().withAnnotationIntrospector(introspector);

        this.configure(org.codehaus.jackson.map.SerializationConfig.Feature.WRAP_ROOT_VALUE, true);
        super.getSerializationConfig().withAnnotationIntrospector(introspector);
    }
}
