java.lang.Object org.springframework.batch.retry.policy.SimpleRetryPolicy
public class SimpleRetryPolicy
Simple retry policy that retries a fixed number of times for a set of named exceptions (and subclasses). The number of attempts includes the initial try, so e.g.
retryTemplate = new RetryTemplate(new SimpleRetryPolicy(3)); retryTemplate.execute(callback);will execute the callback at least once, and as many as 3 times.
