DataSource Proxy

What?

This is a fork of the datasource-proxy project by Tadaya Tsuyukubo.

The aim of the project is to provide a proxy mechanism which provides some hookpoints for collecting information about database query operations for various purposes. This has been used to implement query logging which can write to a number of different logging providers:

• Standard Out
• SLF4J
• Apache Commons

My current goals are:

• Refactor some of the existing code the reduce code duplication
• Make the existing functionality (listeners, filters, interceptors etc.) more configurable
• Add some extra functionality

Improvements

Some stuff that you do in this fork over the original are:

• Specify the format of log messages
• Use aroundQuery in listeners, similar to AOP (instead of just before and after). Useful for profiling.
• Extend existing functionality by injecting dependencies
• Query strings in log messages have the arguments substituted inline

A lot of time has also been spent tidying up the code and refactoring it so theres less duplication. There are also more unit tests (77% code coverage).
