Class RequestHandlerRetryAdvice

java.lang.Object
  org.springframework.integration.context.IntegrationObjectSupport
      org.springframework.integration.handler.advice.AbstractRequestHandlerAdvice
          org.springframework.integration.handler.advice.RequestHandlerRetryAdvice

All Implemented Interfaces:

org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.InitializingBean, NamedComponent, org.springframework.retry.RetryListener

public class RequestHandlerRetryAdvice
extends AbstractRequestHandlerAdvice
implements org.springframework.retry.RetryListener

Uses spring-retry to perform stateless or stateful retry. Stateless retry means the retries are performed internally by the RetryTemplate; stateful retry means the exception is thrown but state is maintained to support the retry policies. Stateful retry requires a RetryStateGenerator.

2.2

target - The target handler.

message - The message that will be sent to the handler.

Returns:

the result after invoking the MessageHandler.

Throws:

java.lang.Exception
