How to restrict the ERROR log to be not printed in the logs when we raised exception in the Groovy script mule. The below is the flow and response.
<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="7475" doc:name="HTTP Listener Configuration"/>
<flow name="ExceptionTestFlow">
<http:listener config-ref="HTTP_Listener_Configuration" path="/test" doc:name="HTTP"/>
<logger level="INFO" doc:name="Logger"/>
<scripting:component doc:name="Groovy">
<scripting:script engine="Groovy"><![CDATA[throw new Exception("Invalid Message")]]></scripting:script>
</scripting:component>
<catch-exception-strategy doc:name="Catch Exception Strategy">
<logger message="#[payload]" level="INFO" doc:name="Logger"/>
</catch-exception-strategy>
</flow>
Response as follows:

It is logging ERROR log and It is going to catch exception strategy. In some scenarios I don't want to log the ERROR(eg: entire ERROR block::: ERROR 2017-02-09 12:13:53,305 [[ExceptionTest].HTTP_Listener_Configuration.worker.01] ) log. Could you please some one assist us how to ignore to be printing the ERROR log in the logs and execute the catch Exception strategy block. note: I need to restrict in application level only.
回答1:
Double click the catch-exception-strategy component to view its properties. And then un-check the Log Exceptions option.
回答2:
Mule runtime 3.7.x does not have the logException attribute defined in its implementation. The solution to avoid stack trace is below.
Define a logger inside the catch-exception-strategy and set the category, along with setting the level to ERROR to notify the message of the exception.
Also, set the category "org.mule.exception.CatchMessagingExceptionStrategy" in the application log4j2.xml to be FATAL
If you want the stacktrace of any particular exception, keep this logger inside that block,
<logger message="Exceptions message is ... #[org.mule.util.ExceptionUtils.getFullStackTrace(exception)]" level="ERROR" doc:name="exceptionLogger"/>
