Reads a correlation id from a request header (or generates one if absent), writes it back into that header and adds it to the SLF4J MDC logging context so it appears in every log line of the request. The MDC entry is removed again on the response (and on abort).

Syntax

correlationId:
  '$ref': <string>
  default: <string>
  header: <string>
  language: groovy
  logField: <string>
  xmlConfig: {}
