Examples of org.springframework.http.client.ClientHttpResponse

org.springframework.http.client.ClientHttpResponse
Represents a client-side HTTP response. Obtained via an calling of the {@link ClientHttpRequest#execute()}.
A ClientHttpResponse must be {@linkplain #close() closed}, typically in a finally block. @author Arjen Poutsma @since 3.0
