Class AsyncRestTemplate

java.lang.Object

org.springframework.http.client.support.AsyncHttpAccessor

org.springframework.web.client.AsyncRestTemplate

All Implemented Interfaces:

AsyncRestOperations

public class AsyncRestTemplate
extends AsyncHttpAccessor
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 it shares its error handler and message converters with this RestTemplate.

For more information, please refer to the RestTemplate API documentation.

4.0

Constructor Detail

AsyncRestTemplate

public AsyncRestTemplate()

Create a new instance of the AsyncRestTemplate using default settings.

This constructor uses a SimpleClientHttpRequestFactory in combination with a SimpleAsyncTaskExecutor for asynchronous execution.

AsyncRestTemplate

AsyncRestTemplate

public AsyncRestTemplate(AsyncClientHttpRequestFactory asyncRequestFactory)

Create a new instance of the AsyncRestTemplate using the given AsyncClientHttpRequestFactory.

This constructor will cast the given asynchronous AsyncClientHttpRequestFactory to a ClientHttpRequestFactory. Since all implementations of ClientHttpRequestFactory provided in Spring also implement AsyncClientHttpRequestFactory, this should not result in a ClassCastException.
