出现异常时重试 spring 集成 IntegrationFlow

Retry spring integration IntegrationFlow on exception

我有一个 spring 集成 IntegrationFlow,其定义如下:

IntegrationFlows.from(Amqp.inboundAdapter(connectionFactory, "queueName")
                    .id("id")
                    .autoStartup(autoStartup)
                    .concurrentConsumers(2)
                    .maxConcurrentConsumers(3)
                    .messageConverter(messageConverter()))
                    .aggregate(a -> ...)
                    .handle(serviceActivatorBean)
                    .get();

serviceActivatorBean 看起来像这样:

@Component
@Transactional
public class ServiceActivator {

    @ServiceActivator

    public void myMethod(Collection<MyEvent> events) {
        ....
    }    
}

如果myMethod 抛出异常,它将被记录但不会重试。我试图将 IntegrationFlow 更改为:

RequestHandlerRetryAdvice advice = new RequestHandlerRetryAdvice();
RetryTemplate retryTemplate = new RetryTemplate();
SimpleRetryPolicy retryPolicy = new SimpleRetryPolicy();
retryPolicy.setMaxAttempts(5);
retryTemplate.setRetryPolicy(retryPolicy);
advice.setRetryTemplate(retryTemplate);

IntegrationFlows.from(Amqp.inboundAdapter(connectionFactory, "queueName")
                    .id("id")
                    .autoStartup(autoStartup)
                    .adviceChain(advice)
                    .concurrentConsumers(2)
                    .maxConcurrentConsumers(3)
                    .messageConverter(messageConverter()))
                    .aggregate(a -> ...)
                    .handle(serviceActivatorBean)
                    .get();

但后来我出现了这样的日志消息(不会重试):

2017-06-30 13:18:10.611 WARN 88706 --- [erContainer#1-2] o.s.i.h.a.RequestHandlerRetryAdvice : This advice org.springframework.integration.handler.advice.RequestHandlerRetryAdvice can only be used for MessageHandlers; an attempt to advise method 'invokeListener' in 'org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer' is ignored

如何配置此 IntegrationFlow 使其与 RabbitListener 的行为相同? IE。让 RabbitMQ 再次发布消息。

在适配器的建议链中使用 retry interceptor 而不是 RequestHandlerRetryAdvice - 如消息所述,这是用于使用端点。
