Class TwitterErrorHandler

java.lang.Object
  org.springframework.web.client.DefaultResponseErrorHandler
      org.springframework.social.twitter.TwitterErrorHandler

All Implemented Interfaces:

ResponseErrorHandler

public class TwitterErrorHandler
extends DefaultResponseErrorHandler

Subclass of DefaultResponseErrorHandler that allows some client and server exceptions to flow through RestTemplate as non-errors. By default, RestTemplate interprets HTTP client (4xx series) errors and server (5xx series) errors as exceptions and throws an HttpClientErrorException. In doing so, this prevents the caller from retrieving the body of the response. When Twitter returns an error, it places some extra information about that error in the body of the response. In order to allow TwitterTemplate to read that information, those errors need to be treated as non-errors by RestTemplate. This puts the burden on TwitterTemplate to interpret the error and act accordingly. But it also enables TwitterTemplate to obtain more information about the nature of the error.
