Spring Integration重试建议配置

Question

只是一个问题，

我想配置一个retryadvice.

这将工作吗?

IntegrationFlows.from("inputChannel")

.transform(theTranformer , "theTransfomerMethod" , e -> e.handleMessageAdvice(new RequestHandlerRetryAdvice()))

.channel("outputChannel").get();

致意。

Answer 1

它将工作，但只有对该handleMessageAdvice的JavaDocs进行注释:

/**
* Configure a list of {@link MethodInterceptor} objects to be applied, in nested order, to the
* endpoint's handler. The advice objects are applied to the {@code handleMessage()} method
* and therefore to the whole sub-flow afterwards.
* @param interceptors the advice chain.
* @return the endpoint spec.
* @since 5.3
*/
public S handleMessageAdvice(MethodInterceptor... interceptors) {

如果你只想重试你的theTransfomerMethod，那么考虑通过以下方式配置这个建议:

/**
* Configure a list of {@link Advice} objects to be applied, in nested order, to the
* endpoint's handler. The advice objects are applied only to the handler.
* @param advice the advice chain.
* @return the endpoint spec.
*/
public S advice(Advice... advice) {
