  Set the message converters to use by this extractor.

• setStatusMapping

  public void setStatusMapping​(Map<HttpStatus,​Class<? extends RestClientException>> statusMapping)

  Set the mapping from HTTP status code to RestClientException subclass. If this mapping has a match for the status code of a given ClientHttpResponse, DefaultResponseErrorHandler.hasError(ClientHttpResponse) will return true and DefaultResponseErrorHandler.handleError(ClientHttpResponse) will attempt to use the configured message converters to convert the response into the mapped subclass of RestClientException.

• setSeriesMapping

  public void setSeriesMapping​(Map<HttpStatus.Series,​Class<? extends RestClientException>> seriesMapping)

  Set the mapping from HTTP status series to RestClientException subclass. If this mapping has a match for the status code of a given ClientHttpResponse, DefaultResponseErrorHandler.hasError(ClientHttpResponse) will return true and DefaultResponseErrorHandler.handleError(ClientHttpResponse) will attempt to use the configured message converters to convert the response into the mapped subclass of RestClientException.

  HttpStatus.isError()

• handleError

  public void handleError​(ClientHttpResponse response,
                          HttpStatus statusCode)
                   throws IOException

  从类复制的说明: DefaultResponseErrorHandler
  Handle the error based on the resolved status code.

  The default implementation delegates to HttpClientErrorException.create(org.springframework.http.HttpStatus, java.lang.String, org.springframework.http.HttpHeaders, byte[], java.nio.charset.Charset) for errors in the 4xx range, to HttpServerErrorException.create(org.springframework.http.HttpStatus, java.lang.String, org.springframework.http.HttpHeaders, byte[], java.nio.charset.Charset) for errors in the 5xx range, or otherwise raises UnknownHttpStatusCodeException.

  覆盖:

  handleError 在类中 DefaultResponseErrorHandler

  抛出:

  IOException

  HttpClientErrorException.create(org.springframework.http.HttpStatus, java.lang.String, org.springframework.http.HttpHeaders, byte[], java.nio.charset.Charset), HttpServerErrorException.create(org.springframework.http.HttpStatus, java.lang.String, org.springframework.http.HttpHeaders, byte[], java.nio.charset.Charset)
