----------------------------------------
Summary: Make request logging more Modular
Key: CXF-6286
URL: https://issues.apache.org/jira/browse/CXF-6286
Project: CXF
Issue Type: Improvement
Components: Core
Reporter: Christian Schneider
Assignee: Christian Schneider
Fix For: 3.1.0
The current request logging is a bit complex as more and more features were
added. I plan to redesign the logging to make it more modular.
As this change is not compatible I will move the logging to a separate module
and mark the request logging in core as deprecated. We can then remove it at a
suitable time.
The new logging design will implement the idea of a cxf LogEvent. This event
will contain all relecvant details cxf can pull out of a request/response.
A LogEventFactory will be reponsible to extract the meta data from a message
and store it in the LogEvent.
The logging interceptors will then mainly be responsible to extract the payload
(which is the complicated part) and call the LogEventFactory to populate the
meta data. They will then send the event to a LogEventSender.
The LogEventSender will default to a slf4j based implementation which will
create MDC values from the meta data. This will allow log4j appenders to work
with the meta data in a convenient way.
Users can also implement their own LogEventSenders and set them in the
LoggingFeature. This allows to implement the logging in a completely different
way while not having to care about the extraction of meta data or payload.
