CXF Interceptors

Description

Bundle provides services extending CXF features

  • CorrelationIdFeature - adds correlationId to all logs. Interceptors from this feature are executed in phases RECEIVE (adding correlationId) and SETUP_ENDING (deleting).
  • LoggingFeature - logs CXF requests and responses. Interceptors from this feature are executed in phase PRE_STREAM.
  • ThreadNameFeature - modify thread name according to ThreadNamePolicy - default policy adds prefix cxf-.

Recommendations

  • CorrelationIdFeature should be added only in locations, where WebService comes (<jaxws:endpoint />), it should not be added to client (<jaxws:client />).

Adding correlationId algorithm

  1. If incoming request has X-CORRELATION-ID header, insert it's value to MDC with key correlationId.
  2. Else if MDC has entry with key correlationId leave this value,
  3. Else generate corrrelationId and insert it to MDC wit key correlationId.
