Two advice in one request-handler-advice-chain

I don't really need the full trace, but I do need all the "Caused by:" lines.

In this case it is:

org.springframework.integration.transformer.MessageTransformationException: org.springframework.integration.MessagingException: failed to transform message headers

Actually I do not know whether this is real problem - I can write some method which will returns all causes and use it in my expression.

string c
Throwable cause <- from integration message

while(cause!=null){
c + = cause
cause = cause.getCause()
}
return c

Jakub

You have too many .cause parts in your expression

Field or property 'cause' cannot be found on null

[Gary Russell]

If you want to handle a variable number of cause parts, add a bean that does the recursion (like you suggested), then use something like...

...cause: '+ @causeAnalyzer.findRootCause(payload)
