Request/response debug logging

Only available if AcrossWebModule is present.

LoggingModule also supports a detailed request/response logging for debugging purposes. It can be used to log the full request and response, including body and headers. Request/response debug logging will wrap the incoming request and outgoing response.

Using the request/response debug logging has a negative impact on performance and can cause side effects in rare cases. Use it only for temporary debugging of specific requests, preferably in a non-production environment.

LoggingModule comes with a set of debug controllers that allow you to view the logs and change the logging settings for specific request paths.


Before request/response logging is possible, it should first be enabled (logging.requestResponse.enabled property).

If request/response logging is enabled, it can still be either active or paused. If logging is not active, no data will be stored and requests/responses will not be wrapped, performance impact will be negligable. The active state can be controlled through the logging.requestResponse.paused property or at runtime via the debug controllers.

Configuration of request/response logging can be done through properties.

Activating request/response logging

Different properties allow you to customize parameters like maximum log entries to keep (defaults to 100), or the paths to include for logging. More advanced configuration can be done through specifying a RequestResponseLogConfiguration instance (logging.requestResponse.configuration property).

Additional configuration options include:

  • to which servlets the filter should apply (defaults to all)

  • the path patterns that requests should match before they are logged

If DebugWebModule is present, the debug controllers allow runtime modifications of the path patterns as well.

Enabling request/response logging for all api requests
LoggingModule loggingModule = new LoggingModule();
loggingModule.setProperty( LoggingModuleSettings.REQUEST_RESPONSE_LOG_ENABLED, true );
RequestResponseLogConfiguration logConfiguration = new RequestResponseLogConfiguration();
logConfiguration.setIncludedPathPatterns( Arrays.asList( "/api/**" ) );
loggingModule.setProperty( LoggingModuleSettings.REQUEST_RESPONSE_LOG_CONFIGURATION, logConfiguration );

Debug controllers

Only available if DebugWebModule is present.

If request/response debug logging is enabled, LoggingModule adds a subsection Request - response to the Logging section. The Settings controller allows you to update the path settings that requests should match before their details are logged. The Overview controller allows you to pause/activate the logging, as well as browse all log entries.
