How to log timeout error in HttpRequestExecutingMessageHandler

I want to be able to log the timeout error exception when using the HttpRequestExecutingMessageHandler. I have done the following:

    @Bean
    public HttpRequestExecutingMessageHandler httpRequestExecutingMessageHandler(ApplicationProperties properties){
        HttpRequestExecutingMessageHandler handler = new HttpRequestExecutingMessageHandler(properties.getWebserviceAppendUrl());
        handler.setExpectedResponseType(String.class);
        handler.setHttpMethod(HttpMethod.POST);
        return handler;
    }

    @Bean
    public IntegrationFlow sendRequestFlow(HttpRequestExecutingMessageHandler httpRequestExecutingMessageHandler,
                                           RequestHandlerRetryAdvice requestHandlerRetryAdvice){
        return IntegrationFlows.from(requestChannel())
                .enrichHeaders(h-> h.header(HttpHeaders.CONTENT_TYPE, "application/json"))
                .handle(httpRequestExecutingMessageHandler, e->e.advice(requestHandlerRetryAdvice))
                .log(LoggingHandler.Level.INFO, "x.xxx.client.config.DevConfig", m-> "Webservice response status code: " + m.getHeaders().get("http_statusCode"))
                .get();
    }

    @Bean
    public RequestHandlerRetryAdvice requestHandlerRetryAdvice(RetryTemplate retryTemplate){
        RequestHandlerRetryAdvice advice = new RequestHandlerRetryAdvice();
        advice.setRetryTemplate(retryTemplate);
        ErrorMessageSendingRecoverer errorMessageSendingRecoverer = new ErrorMessageSendingRecoverer();
        errorMessageSendingRecoverer.setChannel(recoveryChannel());
        advice.setRecoveryCallback(errorMessageSendingRecoverer);
        return advice;
    }

    @Bean
    public RetryTemplate retryTemplate(){
        RetryTemplate retryTemplate = new RetryTemplate();
        SimpleRetryPolicy retryPolicy = new SimpleRetryPolicy();
        retryPolicy.setMaxAttempts(3);
        retryTemplate.setRetryPolicy(retryPolicy);
        FixedBackOffPolicy fixedBackOffPolicy = new FixedBackOffPolicy();
        fixedBackOffPolicy.setBackOffPeriod(60_000L);
        retryTemplate.setBackOffPolicy(fixedBackOffPolicy);
        return retryTemplate;
    }

Currently my log is as follow when there are timeout exception:

DEBUG 2024-01-05 16:19:17,191 [scheduling-1] o.s.r.s.RetryTemplate - Retry: count=0 
DEBUG 2024-01-05 16:20:19,323 [scheduling-1] o.s.r.s.RetryTemplate - Checking for rethrow: count=1 
DEBUG 2024-01-05 16:20:19,323 [scheduling-1] o.s.r.s.RetryTemplate - Retry: count=1 
DEBUG 2024-01-05 16:21:21,340 [scheduling-1] o.s.r.s.RetryTemplate - Checking for rethrow: count=2 
DEBUG 2024-01-05 16:21:21,340 [scheduling-1] o.s.r.s.RetryTemplate - Retry: count=2 
DEBUG 2024-01-05 16:21:23,357 [scheduling-1] o.s.r.s.RetryTemplate - Checking for rethrow: count=3 
DEBUG 2024-01-05 16:21:23,358 [scheduling-1] o.s.r.s.RetryTemplate - Retry failed last attempt: count=3 
WARN 2024-01-05 16:21:23,359 [scheduling-1] o.s.i.h.LoggingHandler - Retrying failed, fallback to recovery flow

But what I want is before the retry logs, I want it to display the timeout error e.g:

ERROR 2024-01-03 13:16:14,220 [scheduling-1] i.b.i.f.c.c.MainConfig - Exception while hitting webservice: I/O error on POST request for "http://somehost/api/v1": Connection timed out: connect; nested exception is java.net.ConnectException: Connection timed out: connect org.springframework.web.client.ResourceAccessException: I/O error on POST request for "http://somehost/api/v1": Connection timed out: connect; nested exception is java.net.ConnectException: Connection timed out: connect
    at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:791)
    at org.springframework.web.client.RestTemplate.exchange(RestTemplate.java:676)
Caused by: java.net.ConnectException: Connection timed out: connect
    at java.net.DualStackPlainSocketImpl.connect0(Native Method)
    at java.net.DualStackPlainSocketImpl.socketConnect(Unknown Source)

I have succesfully add the timeout error with my own message handler but I want to use the HttpRequestExecutingMessageHandler. How to do it using the built in adapter? Any advice is appreciated. Thanks

If you'd like just to log that error, then you can look into RetryListener.onError():

/**
 * Called after every unsuccessful attempt at a retry.
 * @param context the current {@link RetryContext}.
 * @param callback the current {@link RetryCallback}.
 * @param throwable the last exception that was thrown by the callback.
 * @param <T> the return value
 * @param <E> the exception to throw
 */
default <T, E extends Throwable> void onError(RetryContext context, RetryCallback<T, E> callback,
        Throwable throwable) {

Inject that custom listener into your RetryTemplate and implement the logic to determine if that is java.net.ConnectException or not.

This onError() is called before canRetry().
