方法详细资料

setPolicyMap

public void setPolicyMap(Map<Class<? extends Throwable>,RetryPolicy> policyMap)

Setter for policy map used to create a classifier. Either this property or the exception classifier directly should be set, but not both.

参数:

policyMap - a map of Throwable class to RetryPolicy that will be used to create a Classifier to locate a policy.

setExceptionClassifier

public void setExceptionClassifier(Classifier<Throwable,RetryPolicy> exceptionClassifier)

Setter for an exception classifier. The classifier is responsible for translating exceptions to concrete retry policies. Either this property or the policy map should be used, but not both.

参数:

exceptionClassifier - ExceptionClassifier to use

canRetry

public boolean canRetry(RetryContext context)

Delegate to the policy currently activated in the context.

指定者:

canRetry 在接口中 RetryPolicy

参数:

context - the current retry status

返回:

true if the operation can proceed

另请参阅:

• RetryPolicy.canRetry(RetryContext)

close

public void close(RetryContext context)

Delegate to the policy currently activated in the context.

指定者:

close 在接口中 RetryPolicy

参数:

context - a retry status created by the RetryPolicy.open(RetryContext) method of this policy.

另请参阅:

• RetryPolicy.close(RetryContext)

open

public RetryContext open(RetryContext parent)

Create an active context that proxies a retry policy by choosing a target from the policy map.

指定者:

open 在接口中 RetryPolicy

参数:

parent - the parent context if we are in a nested retry.

返回:

a RetryContext object specific to this policy.

• RetryPolicy.open(RetryContext)

registerThrowable

public void registerThrowable(RetryContext context,
 Throwable throwable)

Delegate to the policy currently activated in the context.

指定者:

registerThrowable 在接口中 RetryPolicy

参数:

context - the current status object.

throwable - the exception to throw

• RetryPolicy.registerThrowable(RetryContext, Throwable)
