>                 Key: CAMEL-16139
>                 URL: https://issues.apache.org/jira/browse/CAMEL-16139
>             Project: Camel
>          Issue Type: New Feature
>          Components: camel-jackson
>    Affects Versions: 3.7.1
>         Environment: Camel 3.7+
>            Reporter: Bob Paulin
>            Priority: Minor
>
> The Java DSL offers a simple way to get started marshalling and unmarshaling objects mid route by:
>  
> {code:java}
> .unmarshal().json(JsonLibrary.Jackson, Map.class){code}
>  
> In 3.x an option was added to allow Jackson to automatically discover ObjectMappers in the Camel registry:
> autoDiscoverObjectMapper 
>  
> This is very convenient to apply global Object mapper configurations to an entire application.  However it's defaulted to false and there does not appear to be a way to set this option in the Java DSL without replacing the above code with a DataFormat Object
> EX
> {code:java}
> JacksonDataFormat format = new JacksonDataFormat(Map.class);
> format.setAutoDiscoverObjectMapper(true);
> .unmarshal(format);{code}
> This is a big change to make all over the project.
> I'd like to propose being able to set this option globally in the camel context with the GlobalOptions
> EX
> {code:java}
>  getContext().getGlobalOptions().put("jackson.json.autoDiscoverObjectMapper", "true");{code}
> Then use the Java DSL as is to a ObjectMapper that is already bound in the registry.  Would this be an acceptable approach?  Other options I'm missing. 
>  
> I have a patch with a suggested implementation.
