Issue while Sending JSON Request

I am facing an issue when i am sending a REST request in JSON format.Some of the parameters are getting missed when it invokes the service.However it works fine when i send the request in xml format.The issue which i am geting throws below error:

SEVERE: The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "create_session_param"

The object mapper class looks as below:

objectMapper = new ObjectMapper();
        objectMapper.configure(SerializationFeature.WRAP_ROOT_VALUE, true);

        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,true);

        JaxbAnnotationModule module = new JaxbAnnotationModule();
        // maintain JAXB annotation support
        objectMapper.registerModule(module);

Can someone please help me to resolve this?

Thanks.

You only have WRAP_ROOT_VALUE which is for serialization. Remember serialization is POJO to JSON. The SerializationFeature.WRAP_ROOT_VALUE is the one that actually adds the "create_session_param" when creating the JSON.

We need JSON to POJO, which is deserialization, which has its own feature set. In this case, we need a feature to unwrap the root value in the JSON. For that there is

DeserializationFeature.UNWRAP_ROOT_VALUE

So do

mapper.configure(DeserializationFeature UNWRAP_ROOT_VALUE, true);
