Hi,
I have requirement to get root element from JSON document which I use for
other manipulations. My applications have different apis(heterogeinus) some
includes root element and some do not include root element in the JSON
payload.
SO I need to inspect the payload and check if it has root element, then
plan to set
jacksonObjectMapper.enable(DeserializationFeature.UNWRAP_ROOT_VALUE);
for e.g;
JavaType javaType = getJavaType(type, contextClass);
Annotation rootAnnotation =
javaType.getRawClass().getAnnotation(JsonRootName.class);
if(rootAnnotation != null){
this.getObjectMapper().enable(DeserializationFeature.UNWRAP_ROOT_VALUE);
}
The problem is, some of the JSON objects do not have JsonRoot annotation.
So I am always getting the rootAnnotation as null though root element is
included in the JSON payload.
Is there anyway to check dynamically, weather root element included in
payload(generic way)?
Thanks,
