How to add a global exception handler/logger once in Mule

问题

We want to add a few lines of XML config to mule with an exception handler that logs to SLF4J instead of where they log right now (stdout). How do we add this?

We do NOT want to have to add this handler to every single flow (50+ flows, plus as people add flows, they may forget to add our exception handler).

回答1:

This is an example of "how to share a common exception handler across flows" (in this case a catch-exception-strategy):

<catch-exception-strategy name="myGlobalCatchStrategy">
    <set-payload value="Hey something happened! : #[exception.getSummaryMessage()]" />
</catch-exception-strategy>

<configuration defaultExceptionStrategy-ref="myGlobalCatchStrategy" />

<flow name="global-catch-example">

    <inbound-endpoint address="vm://entry-point.in" exchange-pattern="request-response" />

    <test:component throwException="true" />

</flow>
