public class AsyncRestTemplate extends AsyncHttpAccessor implements AsyncRestOperations
RestTemplate
, but returns ListenableFuture
wrappers as opposed to concrete results.
The AsyncRestTemplate
exposes a synchronous RestTemplate
via the
getRestOperations()
method, and it shares its
error handler and
message converters with this
RestTemplate
.
For more information, please refer to the RestTemplate
API documentation.
