How to declare outputChannel and handle http response for HttpRequestExecutingMessageHandler in spring integration

Question

Below is the configuration of HttpRequestExecutingMessageHandler

@Bean
@ServiceActivator(inputChannel = "httpRequestChannel")
    public HttpRequestExecutingMessageHandler httpRequestExecutingMessageHandler() {
    HttpRequestExecutingMessageHandler handler = new HttpRequestExecutingMessageHandler(serviceUrl);
    handler.setCharset(StandardCharsets.UTF_8.displayName());
    handler.setOutputChannel(httpResponseChannel());
    handler.setExpectedResponseType(String.class);

    return handler;
}

How should i configure httpResponseChannel to handle the httpResponse. I want to move origin file to success folder if http status code is 201 or to error folder for rest.

I'm using spring integration 5 with spring boot together.

It's not a httpResponseChannel responsibility. You need to consider to add an ExpressionEvaluatingRequestHandlerAdvice for this HttpRequestExecutingMessageHandler: https://docs.spring.io/spring-integration/docs/5.0.6.RELEASE/reference/html/messaging-endpoints-chapter.html#expression-advice

And already there you can make a decision about success or failure.

The @ServiceActivator has this option on the matter:

/**
 * Specify a "chain" of {@code Advice} beans that will "wrap" the message handler.
 * Only the handler is advised, not the downstream flow.
 * @return the advice chain.
 */
String[] adviceChain() default { };
