Class FacesRequestLogger

java.lang.Object

org.omnifaces.eventlistener.DefaultPhaseListener

org.omnifaces.eventlistener.FacesRequestLogger

All Implemented Interfaces:

Serializable, EventListener, PhaseListener

public class FacesRequestLogger
extends DefaultPhaseListener

The FacesRequestLogger is a PhaseListener which logs the Faces request detail as Level.INFO. The log format is as below:

 method{url, user, action, params, messages, timer}
 

Where:

• method: the HTTP request method, usually GET or POST.
• url: the request URI with query string.
• user: the user detail, composed of:
  • ip: the user IP, as obtained by Faces.getRemoteAddr().
  • login: the user login, as obtained by Faces.getRemoteUser().
  • session: the session ID, as obtained by Faces.getSessionId().
  • viewState: the server side JSF view state identifier, if any.
• action: the action detail, composed of:
  • source: the action source, as obtained by Components.getCurrentActionSource().
  • event: the action event name, if any.
  • methods: the action methods, as obtained by Components.getActionExpressionsAndListeners(UIComponent)
  • validationFailed: whether JSF validation has failed.
• params: the HTTP request parameters whereby any parameters whose name matches javax.faces.* are skipped, and whose name ends with password or token are masked with value ********.
• messages: all Faces messages added so far.
• timer: the duration of each phase measured in milliseconds, or -1 if the phase has been skipped, composed of:
  • 0: total time.
  • 1: duration of PhaseId.RESTORE_VIEW.
  • 2: duration of PhaseId.APPLY_REQUEST_VALUES.
  • 3: duration of PhaseId.PROCESS_VALIDATIONS.
  • 4: duration of PhaseId.UPDATE_MODEL_VALUES.
  • 5: duration of PhaseId.INVOKE_APPLICATION.
  • 6: duration of PhaseId.RENDER_RESPONSE.

Specified by:

afterPhase in interface PhaseListener

Overrides:

afterPhase in class DefaultPhaseListener

getLogDetails

Parameters:

context - The involved faces context.

Returns:

Log details.

getUserDetails

protected Map<String,Object> getUserDetails(FacesContext context)

You can override this if you need more fine grained control over logging of user details.

Parameters:

context - The involved faces context.

Returns:

User details.

getActionDetails

protected Map<String,Object> getActionDetails(FacesContext context)

You can override this if you need more fine grained control over logging of action details.

Parameters:

context - The involved faces context.
