public class RestTemplate extends InterceptingHttpAccessor implements RestOperations
Note: by default the RestTemplate 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 through the
HttpAccessor.setRequestFactory(org.springframework.http.client.ClientHttpRequestFactory) property.
The main entry points of this template are the methods named after the six main HTTP methods:
In addition the exchange and execute methods are generalized versions of
the above methods and can be used to support additional, less frequent combinations (e.g.
HTTP PATCH, HTTP PUT with response body, etc.). Note however that the underlying HTTP
library used must also support the desired combination.
For each HTTP method there are three variants: two accept a URI template string
and URI variables (array or map) while a third accepts a URI.
Note that for URI templates it is assumed encoding is necessary, e.g.
restTemplate.getForObject("http://example.com/hotel list") becomes
"http://example.com/hotel%20list". This also means if the URI template
or URI variables are already encoded, double encoding will occur, e.g.
http://example.com/hotel%20list becomes
http://example.com/hotel%2520list). To avoid that use a URI method
variant to provide (or re-use) a previously encoded URI. To prepare such an URI
with full control over encoding, consider using
UriComponentsBuilder.
Internally the template uses HttpMessageConverter instances to
convert HTTP messages to and from POJOs. Converters for the main mime types
are registered by default but you can also register additional converters
via setMessageConverters(java.util.List<org.springframework.http.converter.HttpMessageConverter<?>>).
This template uses a
SimpleClientHttpRequestFactory and a
DefaultResponseErrorHandler as default strategies for creating HTTP
connections or handling HTTP errors, respectively. These defaults can be overridden
through HttpAccessor.setRequestFactory(org.springframework.http.client.ClientHttpRequestFactory) and setErrorHandler(org.springframework.web.client.ResponseErrorHandler) respectively.
