Hi all,
After some times I started again to work on the problem of content
based routing, and I still don't see clearly how to achieve some goals.
I agree on using existing things instead than creating new mediators: we
would prefer to use the Switch Mediator, if that's possible, because the
Router Mediator has not graphical interface for configuration.
I will try to make myself clear about what I am trying to achieve:
Having a sequence composed in such way:
Switch Mediator
Header Mediator
Log Mediator
[eventually other Mediators]
[...]
I would need to decide in the Switch Mediator the Endpoint to send the
request at, without skipping the following Mediators in the sequence:
Switch Mediator
matches case A: set for later sending to Endpoint ALFA [at the end
of mediator chain]
matches case B: set for later sending to Endpoint BETA [at the end
of mediator chain]
default: set for later sending to Endpoint GAMMA [at the end of
mediator chain]
Header Mediator
Log Mediator
[eventually other Mediators]
[...]
[Perform sending to the endpoint set in the Switch Mediator]
>From what I have seen so far, the only way to change the Endpoint in the
Switch Mediator is "nesting" a Send Mediator inside a case in the
switch, but doing that way the remaining mediators in the sequence are
skipped...
Having a glance at the source code of the Send Mediator I understood
that its invocation is performing a send action to an endpoint, so using
it means to "jump out" the sequence going straight to the Endpoint.
After configuring the sequence adding a Switch Mediator which contains a
Send Mediator, while checking logs I have noticed that after such line:
INFO TRACE_LOGGER Sending message to endpoint : SERVICE_ENDPOINT resolves to
address =
http://xxxxx.xxxx.xxxxxx.net:5013//samws/services/IStreamAccessManagerService
the sequence goes ahead processing the message and I see i.e some
logging related to some headers modifications.
Basically I would need to understand a bit more clearly:
1) What happens with the other Mediators when I add a Send Mediator
inside a case of the Switch Mediator?
2) Is it possible to "set" in the Switch Mediator the Endpoint that must
be used when sending, for performing the effective sending just after
the message is processed by the whole chain of Mediators?
Our basic requirement is just having the capability to route the message
to a specific endpoint after the whole processing of the message by a
sequence of mediators.
I hope I was able to explain a bit better the kind of problem we are
trying to solve.
Thanks a lot
L.
