Logging SOAP message on http gateway spring integration - spring-integration

Question

I am using spring integration (4.0.6) to make SOAP calls from rest service using int-http:outbound-gateway and int-ws:outbound-gateway. Is there a way to log SOAP request message only in case of exception.
<int:gateway id="myGateway" service-interface="myservice">
<int:method name="getData" request-channel="reqChannel" reply-channel="repChannel">
</int-gateway>
my outbound-gateway configured as below
<int-http:outbound-gateway id="og1" request-channel="reqChannel" url="xxx" http-method="POST" reply-channel="repChannel" reply-timeout="10000" message-converters="converter" request-factory="reqFactory">
<bean id="reqFactory"
class="org.springframework.http.client.SimpleClientHttpRequestFactory">
<property name="cTimeout" value="20000"/>
<property name="rTimeout" value="20000"/>
</bean>

Answer 1

Ok, Try this method.
Create your own error Handler which implements the spring Error Handler Interface. In your context file
<bean id="soapErrorHandlingSyncTaskExecutor"
class="org.springframework.integration.util.ErrorHandlingTaskExecutor">
<constructor-arg>
<bean class="org.springframework.core.task.SyncTaskExecutor" />
</constructor-arg>
<constructor-arg>
<bean class="ErrorHandle"
p:errorSender-ref="errorSender"/>
</constructor-arg>
</bean>
<bean id="errorSender" class="org.springframework.integration.core.MessagingTemplate"
p:defaultChannel-ref="errors" />
When ever your WS adapter throws any exception then org.springframework.integration.util.ErrorHandlingTaskExecutor catches this exception now its upto you how you handle the exception in your error handler.
The SOAP faultcode and faultstring is found in the MessagingException's cause (if a SoapFaultClientException).
Here i am sending the error messages to a channel for me to monitor.
Hope this helps.

Would be better to share some config and the point where would you like to get a log/exception.
Both, <int-http:outbound-gateway> and <int-ws:outbound-gateway> have <request-handler-advice-chain> ability, where you could use ExpressionEvaluatingRequestHandlerAdvice and send an ErrorMessage with the request (guilty?) message for any diagnostics.
You should configure the readTimeout on the appropriate ClientHttpRequestFactory, e.g. HttpComponentsClientHttpRequestFactory#setReadTimeout(int timeout).
Regarding converters and the wish to log their results in case of error...
How about to implement ClientHttpRequestInterceptor with the desired logic:
try {
return execution.execute(request, body);
catch (Exception e) {
this.errorChannel.send(...);
}
I'm prety sure that the byte[] body is your SOAP request.
See ClientHttpRequestInterceptor JavaDocs for more info.
The ClientHttpRequestInterceptor is part of RestTemplate, which can be injected to the http:outbound-gateway.
For the ws:outbound-gateway you should use ClientInterceptor with the handleFault implementation and extract MessageContext.getRequest() for your purpose.
