How does P6SPY work?

Pretty much everything in the question. I just discovered p6spy in association with hibernate which is really cool to see the actual sql queries, though I'm quite baffled on how it works.
So how does it work?

the basic idea on p6spy goes like this:

  1. depending if you go for Datasource or for JDBC driver in your code, what you do is instead of referring the real ones, you specify p6spy specific ones: com.p6spy.engine.spy.P6SpyDriver or com.p6spy.engine.spy.P6DataSource respectively (for full documentation, see: p6spy.readthedocs.io/en/latest/configandusage.html).
  2. afterwards you configure the real ones in your spy.properties file (using realdriver or realdatasource properties respectively)
  3. depending on the configuration you can achieve the logging of sql statements (using com.p6spy.engine.logging.P6LogFactory)
  4. so to answer your question, the idea is that all the jdbc calls (statements execution, transaction related stuff) will be wrapped (proxied) by p6spy and depending on your configuration, these can be logged via the file logger (using appender=com.p6spy.engine.logging.appender.FileLogger), stdout logger (using appender=com.p6spy.engine.logging.appender.StdoutLogger) or log4j logger (using: appender=com.p6spy.engine.logging.appender.Log4jLogger)
