RestOperations
```
public class RestTemplate
extends InterceptingHttpAccessor
implements RestOperations
```
Synchronous client to perform HTTP requests, exposing a simple, template method API over underlying HTTP client libraries such as the JDK HttpURLConnection, Apache HttpComponents, and others.
The RestTemplate offers templates for common scenarios by HTTP method, in addition to the generalized exchange and execute methods that support of less frequent cases.
NOTE: As of 5.0 this class is in maintenance mode, with only minor requests for changes and bugs to be accepted going forward. Please, consider using the org.springframework.web.reactive.client.WebClient which has a more modern API and supports sync, async, and streaming scenarios.

```
public RestTemplate()
```
    Create a new instance of the RestTemplate using default settings. Default HttpMessageConverters are initialized.
  - RestTemplate
```
public RestTemplate(ClientHttpRequestFactory requestFactory)
```
    Create a new instance of the RestTemplate based on the given ClientHttpRequestFactory.
    参数:
    requestFactory - the HTTP request factory to use
    另请参阅:
    SimpleClientHttpRequestFactory, HttpComponentsClientHttpRequestFactory
  - RestTemplate
```
public RestTemplate(List<HttpMessageConverter<?>> messageConverters)
```
    Create a new instance of the RestTemplate using the given list of HttpMessageConverter to use.
    参数:
    messageConverters - the list of HttpMessageConverter to use
    从以下版本开始:
    3.2.7
- 方法详细资料
  - setMessageConverters
```
public void setMessageConverters(List<HttpMessageConverter<?>> messageConverters)
```
    Set the message body converters to use.
    These converters are used to convert from and to HTTP requests and responses.
  - getMessageConverters
```
public List<HttpMessageConverter<?>> getMessageConverters()
```
    Return the list of message body converters.
    The returned List is active and may get appended to.
  - setErrorHandler
```
public void setErrorHandler(ResponseErrorHandler errorHandler)
```
    Set the error handler.
    By default, RestTemplate uses a DefaultResponseErrorHandler.
  - getErrorHandler
```
public ResponseErrorHandler getErrorHandler()
```
    Return the error handler.
  - setDefaultUriVariables
```
public void setDefaultUriVariables(Map<String,?> uriVars)
```
    Configure default URI variable values. This is a shortcut for:
    DefaultUriBuilderFactory factory = new DefaultUriBuilderFactory(); handler.setDefaultUriVariables(...); RestTemplate restTemplate = new RestTemplate(); restTemplate.setUriTemplateHandler(handler);
    参数:
    uriVars - the default URI variable values
    从以下版本开始:
    4.3
  - setUriTemplateHandler
```
public void setUriTemplateHandler(UriTemplateHandler handler)
```
    Configure a strategy for expanding URI templates.
    By default, DefaultUriBuilderFactory is used and for backwards compatibility, the encoding mode is set to URI_COMPONENT. As of 5.0.8, prefer using TEMPLATE_AND_VALUES.
    Note: in 5.0 the switch from DefaultUriTemplateHandler (deprecated in 4.3), as the default to use, to DefaultUriBuilderFactory brings in a different default for the parsePath property (switching from false to true).
    参数:
    handler - the URI template handler to use
  - getUriTemplateHandler
```
public UriTemplateHandler getUriTemplateHandler()
```
    Return the configured URI template handler.
