Remove null fields from JSON payload in requests

[Jose María Zaragoza]

Hello:

I'm using CXF 2.7.8

I've created a REST service . Format for POST messages is JSON

Sometimes , the service receives null values

{ .... , ·"field": null , .....}


I want to develop a JAXRS filter to remove this fields.
So, I need to modify message . I would like to know if :

is there any JAXRS template to extract JSON fields and remove them dynamically ?
other choice?
something as Transformation Feature ?


Example Filter :

@Override
public Response handleRequest(Message  message, ClassResourceInfo resourceClass)
{
@SuppressWarnings("unchecked")
MetadataMap<String, String> map =  (MetadataMap<String, String>)
message.get("jaxrs.template.???????");

 if(null != map)
        {

        for (Map.Entry<String, List<String>> entry: map.entrySet())
        {
        System.out.println("key:" + entry.getKey() + "- value:" +
entry.getValue());
        }

        }
   return null;

}
