- org.springframework.web.client.DefaultResponseErrorHandler

All Implemented Interfaces:
ResponseErrorHandler
```
public class DefaultResponseErrorHandler
extends Object
implements ResponseErrorHandler
```
Spring's default implementation of the ResponseErrorHandler interface.
This error handler checks for the status code on the ClientHttpResponse: Any code with series HttpStatus.Series.CLIENT_ERROR or HttpStatus.Series.SERVER_ERROR is considered to be an error; this behavior can be changed by overriding the hasError(HttpStatus) method. Unknown status codes will be ignored by hasError(ClientHttpResponse).
Since:
3.0

`protected byte[]`	`getResponseBody(ClientHttpResponse response)`	Read the body of the given response (for inclusion in a status exception).
`void`	`handleError(ClientHttpResponse response)`	This default implementation throws a `HttpClientErrorException` if the response status code is `HttpStatus.Series.CLIENT_ERROR`, a `HttpServerErrorException` if it is `HttpStatus.Series.SERVER_ERROR`, and a `RestClientException` in other cases.
`protected boolean`	`hasError(int unknownStatusCode)`	Template method called from `hasError(ClientHttpResponse)`.
`boolean`	`hasError(ClientHttpResponse response)`	Delegates to `hasError(HttpStatus)` (for a standard status enum value) or `hasError(int)` (for an unknown status code) with the response status code.

    Specified by:
    hasError in interface ResponseErrorHandler
    Parameters:
    response - the response to inspect
    Returns:
    true if the response indicates an error; false otherwise
    Throws:

  - hasError
```
protected boolean hasError(HttpStatus statusCode)
```
    Template method called from hasError(ClientHttpResponse).

  - hasError
```
protected boolean hasError(int unknownStatusCode)
```
    Template method called from hasError(ClientHttpResponse).
    The default implementation checks if the given status code is HttpStatus.Series#CLIENT_ERROR CLIENT_ERROR or HttpStatus.Series#SERVER_ERROR SERVER_ERROR. Can be overridden in subclasses.
    Parameters:
    unknownStatusCode - the HTTP status code as raw value
    Returns:
    true if the response indicates an error; false otherwise

  - handleError
```
public void handleError(ClientHttpResponse response)
                 throws IOException
```
    This default implementation throws a HttpClientErrorException if the response status code is HttpStatus.Series.CLIENT_ERROR, a HttpServerErrorException if it is HttpStatus.Series.SERVER_ERROR, and a RestClientException in other cases.
    Specified by:
    handleError in interface ResponseErrorHandler
    Parameters:
    response - the response with the error
    Throws:
    IOException - in case of I/O errors
  - getHttpStatusCode
```
protected HttpStatus getHttpStatusCode(ClientHttpResponse response)
                                throws IOException
```
    Determine the HTTP status of the given response.
