handleAndWrapHttpResponseException()

static RuntimeException org.keycloak.authorization.client.util.Throwables.handleAndWrapHttpResponseException ( HttpResponseException  exception )

handleWrapException()

static RuntimeException org.keycloak.authorization.client.util.Throwables.handleWrapException ( String  message, Throwable  cause  )

inlinestatic

Handles an

cause 

and wraps it into a RuntimeException. The resulting cause contains more details in case the given

cause 

is of a HttpResponseException.

引数

callable
pat
message	the message
cause	the root cause

戻り値

a RuntimeException wrapping the given

cause 

                                                                                        {
        if (cause instanceof HttpResponseException) {
            throw handleAndWrapHttpResponseException(HttpResponseException.class.cast(cause));
        }

        return new RuntimeException(message, cause);
    }

retryAndWrapExceptionIfNecessary()

static <V> V org.keycloak.authorization.client.util.Throwables.retryAndWrapExceptionIfNecessary ( Callable< V >  callable, TokenCallable  token, String  message, Throwable  cause  ) throws RuntimeException

inlinestatic

Retries the given

callable 

after obtaining a fresh

token 

from the server. If the attempt to retry fails the exception is handled as defined by handleWrapException(String, Throwable).

A retry is only attempted in case the

cause 

is a HttpResponseException with a 403 status code. In some cases the session associated with the token is no longer valid and a new token must be issues.

引数

callable	the callable to retry
token	the token
message	the message
cause	the cause
<V>	the result of the callable

戻り値

the result of the callable

例外

RuntimeException

in case the attempt to retry fails
