All Implemented Interfaces:
AsyncRestOperations
```
public class AsyncRestTemplate
extends InterceptingAsyncHttpAccessor
implements AsyncRestOperations
```
Spring's central class for asynchronous client-side HTTP access. Exposes similar methods as RestTemplate, but returns ListenableFuture wrappers as opposed to concrete results.
The AsyncRestTemplate exposes a synchronous RestTemplate via the getRestOperations() method and shares its error handler and message converters with that RestTemplate.
Note: by default AsyncRestTemplate relies on standard JDK facilities to establish HTTP connections. You can switch to use a different HTTP library such as Apache HttpComponents, Netty, and OkHttp by using a constructor accepting an AsyncClientHttpRequestFactory.
For more information, please refer to the RestTemplate API documentation.
