Method Detail

isConnectionException

public boolean isConnectionException(java.lang.Throwable e)

isRetriableException

public boolean isRetriableException(java.lang.Throwable e,
                                    boolean sameServer)

Description copied from interface: RetryHandler

Test if an exception is retriable for the load balancer

Specified by:

isRetriableException in interface RetryHandler

Parameters:

e - the original exception

sameServer - if true, the method is trying to determine if retry can be done on the same server. Otherwise, it is testing whether retry can be done on a different server

isCircuitTrippingException

public boolean isCircuitTrippingException(java.lang.Throwable e)

Description copied from interface: RetryHandler

Test if an exception should be treated as circuit failure. For example, a ConnectException is a circuit failure. This is used to determine whether successive exceptions of such should trip the circuit breaker to a particular host by the load balancer. If false but a server response is absent, load balancer will also close the circuit upon getting such exception.

Specified by:

isCircuitTrippingException in interface RetryHandler

getMaxRetriesOnSameServer

public int getMaxRetriesOnSameServer()

Specified by:

getMaxRetriesOnSameServer in interface RetryHandler

Returns:

Number of maximal retries to be done on one server

getMaxRetriesOnNextServer

public int getMaxRetriesOnNextServer()

Specified by:

getMaxRetriesOnNextServer in interface RetryHandler

Returns:

Number of maximal different servers to retry
