  public boolean hasError​(ClientHttpResponse response)
                   throws IOException

  指定者:

  hasError 在接口中 ResponseErrorHandler

  参数:

  response - the response to inspect

  返回:

  true if the response indicates an error; false otherwise

  抛出:

  IOException - in case of I/O errors

  ClientHttpResponse.getRawStatusCode(), hasError(HttpStatus), hasError(int)

• hasError

  protected boolean hasError​(HttpStatus statusCode)

  Template method called from hasError(ClientHttpResponse).

  The default implementation checks HttpStatus.isError(). Can be overridden in subclasses.

  参数:

  statusCode - the HTTP status code as enum value

  返回:

  true if the response indicates an error; false otherwise

  另请参阅:

  HttpStatus.isError()

• hasError

  protected boolean hasError​(int unknownStatusCode)

  Template method called from hasError(ClientHttpResponse).

  The default implementation checks if the given status code is CLIENT_ERROR or SERVER_ERROR. Can be overridden in subclasses.

  参数:

  unknownStatusCode - the HTTP status code as raw value

  返回:

  true if the response indicates an error; false otherwise

• handleError

  public void handleError​(ClientHttpResponse response)
                   throws IOException

  Handle the error in the given response with the given resolved status code.

  The default implementation throws:

  • HttpClientErrorException if the status code is in the 4xx series, or one of its sub-classes such as HttpClientErrorException.BadRequest and others.
  • HttpServerErrorException if the status code is in the 5xx series, or one of its sub-classes such as HttpServerErrorException.InternalServerError and others.
  • UnknownHttpStatusCodeException for error status codes not in the HttpStatus enum range.

  指定者:

  handleError 在接口中 ResponseErrorHandler

  参数:

  response - the response with the error

  抛出:

  UnknownHttpStatusCodeException - in case of an unresolvable status code

  IOException - in case of I/O errors

  另请参阅:

  handleError(ClientHttpResponse, HttpStatus)

• handleError

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

  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.

  抛出:

  IOException
