Annotation Type ExponentialRetry

@Target(value=METHOD)
@Retention(value=RUNTIME)
public @interface ExponentialRetry

This annotation can be used for retrying failures on any asynchronous executions. For retrying based on dynamic retry policy use RetryDecorator. Both @ExponentialRetry annotation and RetryDecorator should not be used simultaneously on the same asynchronous method call.

Required Element Summary

long	initialRetryIntervalSeconds Retry period to use for the first retry by ExponentialRetryPolicy.

Optional Element Summary

double	backoffCoefficient Coefficient to use for exponential retry policy.
Class<? extends Throwable>[]	exceptionsToRetry Default is Throwable which means that all exceptions are retried.
Class<? extends Throwable>[]	excludeExceptions What exceptions that match exceptionsToRetry list should be not retried.
int	maximumAttempts Number of maximum retry attempts used by ExponentialRetryPolicy.
long	maximumRetryIntervalSeconds Maximum retry period between attempts used by ExponentialRetryPolicy.
long	retryExpirationSeconds Expiration period of retries used by ExponentialRetryPolicy.

Element Detail

initialRetryIntervalSeconds

public abstract long initialRetryIntervalSeconds

Retry period to use for the first retry by ExponentialRetryPolicy. This value should not be greater than values specified for maximumRetryPeriod or retryExpirationPeriod.

maximumRetryIntervalSeconds

public abstract long maximumRetryIntervalSeconds

Maximum retry period between attempts used by ExponentialRetryPolicy. This value should not be less than value specified for initialRetryPeriod. Default value is unlimited.

Default:

-1L

retryExpirationSeconds

public abstract long retryExpirationSeconds

Expiration period of retries used by ExponentialRetryPolicy. This value should not be less than value specified for initialRetryPeriod. Default value is unlimited.

Default:

-1L

backoffCoefficient

public abstract double backoffCoefficient

Coefficient to use for exponential retry policy. Default is 2.0.

Default:

2.0

maximumAttempts

public abstract int maximumAttempts

Number of maximum retry attempts used by ExponentialRetryPolicy. Default value is no limit.

Default:

-1

exceptionsToRetry

public abstract Class<? extends Throwable>[] exceptionsToRetry

Default is Throwable which means that all exceptions are retried.

Default:

java.lang.Throwable.class

excludeExceptions

public abstract Class<? extends Throwable>[] excludeExceptions

What exceptions that match exceptionsToRetry list should be not retried. Default is empty list.

Default:

{}
