Jackson unwrap object in array

Hi I have some JSON which is wrapped as so:

{
  rootNode: [{
    "property":"value"
  }]
}

Is there a way of getting the object in the array as:

@JsonRootName("rootNode")
public class ThisClass{
  private String property;
}

If there is no array I can just use the rootnode notation are there any other annotations to compensate for the wrapped array?

Was able to get this working by setting some options on ObjectMapper

mapper
.configure(DeserializationFeature.UNWRAP_ROOT_VALUE, true),
.configure(DeserializationFeature.UNWRAP_SINGLE_VALUE_ARRAYS);

You can parse this JSON by enabling the following deserialization options in jackson:

ObjectMapper mapper = new ObjectMapper();
mapper.enable(DeserializationFeature.UNWRAP_SINGLE_VALUE_ARRAYS);
mapper.enable(DeserializationFeature.UNWRAP_ROOT_VALUE);

Check the docs for details
