Hi,
I´m currently implementing a mediator which logs certain values of a
mediation to a MySQL RDBMS.
I guess you can use the newly introduced ManagedLifeCycle concept to get the
DB connection handling if you are using the svn head rather than the
released version..... (just a thought)
I use the 1.0 version.
How can I retrieve the following information in mediate() from the
synapse messagecontext:
- Name or URL of the Synapse WS-Proxy the client used
SynapseMessageContext.getTo().getAddress()
Just FYI. One can also use:
String proxy_name = (String) synCtx.getProperty("proxy.name");
(for retrieving the proxy name directly)
- Timestamp, when the message arrived in Synapse
- Timestamp, when the reply from the backendservice arrived in synapse
(when isResponse is true)
AFAIK, you can not retrieve the timestamp information for the received time
from the MessageContext. Sorry. If this is required we can add this
information to MC at the time we create it as a property in the MC so that
you can get it using the MessageContext.getProperty.
It would be nice to know the time of a backend service invocation. A use
case for this is to confirm a SLA for a backend service (e.g. "Backend
service xy must answer any request in no more than 1 second).
If you want to add this feature go ahead :)
I´ve written my own mediator for this now that logs a timestamp before
and after the backend invocation in the messagecontext properties.
Also I´m looking for a way to store data in the messagecontext while in
inSequence that I can retrieve again in the outSequence. Is this
possible or will I have to store it somewhere outside of synapse?
Yes. you can use MessageContext.setProperty(String key, Object value) to set
the information as a property in to the MC in the inSequence and retrieve
those information in the outSequence using the
MessageContext.getProperty(String
key) [note: you should use the same key (obviously :D)]
Perfect.
Thanks.
Michael
