raftsman Spy is an open source and free framework for JDBC logging. It is a JDBC driver implementation.
This logger logs all SQL connection and processings with execution spent time, all the stored procedures with arguments, all the batch processings and the result sets.
No need to modify your application in order to integrate JDBC logging with Craftsman Spy. The application MUST use the craftsman.spy.SpyDriver and MUST be launched with the -Dspy.driver=... system property.
Be carefull this JDBC driver SHOULD not be used in production mode. Use it only in development or pre-production system.
