Method Detail

handleError

public void handleError(org.springframework.http.client.ClientHttpResponse response)
                 throws org.springframework.security.authentication.BadCredentialsException,
                        IOException

The error handler intercepts the default error handler and checks if the returned HTTP status code is 400 Bad Request. This status code particularly indicates that the authentication failure was not caused by the client or services, but was caused by invalid credentials or other account-related issues (e.g. account disabled).

The method attempts to read the error description from the response body.

Specified by:

handleError in interface org.springframework.web.client.ResponseErrorHandler
