Examples of RetryTemplate

org.springframework.osgi.service.importer.support.internal.support.RetryTemplate
Wrapper retry template. This class does specialized retries using a given callback and lock. @author Costin Leau
org.springframework.retry.support.RetryTemplate
Template class that simplifies the execution of operations with retry semantics.
Retryable operations are encapsulated in implementations of the {@link RetryCallback}interface and are executed using one of the supplied execute methods.
By default, an operation is retried if is throws any {@link Exception} or subclass of{@link Exception}. This behaviour can be changed by using the {@link #setRetryPolicy(RetryPolicy)} method.
Also by default, each operation is retried for a maximum of three attempts with no back off in between. This behaviour can be configured using the {@link #setRetryPolicy(RetryPolicy)} and {@link #setBackOffPolicy(BackOffPolicy)}properties. The {@link org.springframework.retry.backoff.BackOffPolicy} controls howlong the pause is between each individual retry attempt.
This class is thread-safe and suitable for concurrent access when executing operations and when performing configuration changes. As such, it is possible to change the number of retries on the fly, as well as the {@link BackOffPolicy} used and no in progressretryable operations will be affected. @author Rob Harrop @author Dave Syer @author Gary Russell @author Artem Bilan
