Advanced usage of Intercpt

The interceptFrom and interceptSendToEndpoint supports endpoint URI matching by the following rules in the given order:

• match by exact URI name. This is the sample we have seen above.
• match by wildcard
• match by regular expression.

Match by wildcard

Match by wildcard allows you to match a range of endpoint or all of a given type. For instance use uri="file:*" will match all File based endpoints.

intercept("jms:*").to("log:fromjms");

Wildcards is match that the text before the * is matched against the given endpoint and if it also starts with the same characters its a match. For instance you can do:

intercept("file://order/inbox/*").to("log:newfileorders");

To intercept any files received from the order/inbox folder.

Match by regular expression

Match by regular expression is just like match by wildcard but using regex instead. So if we want to intercept incoming messages from gold and silver JMS queues we can do:

intercept("jms:queue:(gold|silver)").to("seda:handleFast");
