Class RetryOperationsInterceptor

java.lang.Object
  org.springframework.batch.retry.interceptor.RetryOperationsInterceptor

All Implemented Interfaces:

org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor

public class RetryOperationsInterceptor
extends Object
implements org.aopalliance.intercept.MethodInterceptor

A MethodInterceptor that can be used to automatically retry calls to a method on a service if it fails. The injected RetryOperations is used to control the number of retries. By default it will retry a fixed number of times, according to the defaults in RetryTemplate.
Hint about transaction boundaries. If you want to retry a failed transaction you need to make sure that the transaction boundary is inside the retry, otherwise the successful attempt will roll back with the whole transaction. If the method being intercepted is also transactional, then use the ordering hints in the advice declarations to ensure that this one is before the transaction interceptor in the advice chain.
