Renaming MDC field

[mathewsreji]

I am trying to plug in the encoder with a java app which uses apache camel framework. The framework already has some inbuilt MDC information as shown here -> https://people.apache.org/~dkulp/camel/mdc-logging.html

I want to rename certain fields in the log output. For example, instead of following

{"application_name":"roma-runtime","timestamp":"2020-05-06T13:48:16.366Z","logger":"org.apache.camel.impl.DefaultCamelContext","level":"INFO","class":"org.apache.camel.impl.DefaultCamelContext","method":"start","file":"DefaultCamelContext.java","line":3186,"thread":"http-nio-8888-exec-3","camel.contextId":"53081f9c-6d51-4f98-8c9d-439de1fcd1db","message":"Total 3 routes, of which 3 are started"}

I want camel.contextId to be renamed to integration_id. as follows

{"application_name":"roma-runtime","timestamp":"2020-05-06T13:48:16.366Z","logger":"org.apache.camel.impl.DefaultCamelContext","level":"INFO","class":"org.apache.camel.impl.DefaultCamelContext","method":"start","file":"DefaultCamelContext.java","line":3186,"thread":"http-nio-8888-exec-3","integration_id":"53081f9c-6d51-4f98-8c9d-439de1fcd1db","message":"Total 3 routes, of which 3 are started"}

Is there a way I can configure this name mapping in my logback-spring.xml file?

I've added support for this in the next version.

If you need something before the next version is released, you can disable writing the MDC, and add your own custom JsonProvider that outputs the MDC using custom field names.
