/**
* Implementation of {@link org.springframework.http.converter.HttpMessageConverter}
* that can read and write JSON using the
* Google Gson library's
* {@link Gson} class.
*
*
This converter can be used to bind to typed beans or untyped {@code HashMap}s.
* By default, it supports {@code application/json} and {@code application/*+json}.
*
*
Tested against Gson 2.3; compatible with Gson 2.0 and higher.
