jdbc-tracer is a JDBC driver, which provides hook points to trace all queries.

## Use cases

* Record all statements executed by JDBC driver
* Detect heavy queries in development environment.
* Send EXPLAIN statement
* Logging queries and parameters.
* Detect webapp controller, that sends too much SQL queries.

## Listeners

You need to implement PreparedStatementListener or ResultSetListener.

### PreparedStatementListener

You can get following values for each executed queries:

* connection
* elapsed time
* SQL statement
* binded variables

### ResultSetListener

You can get following values for each got rows:

* isFirstRow
* You may print column information on first row.
* resultSet
* you can get resultset information!
* (MUST NOT call `next()` from the listener. it cause infinite loop)

## Install

You can install this library from maven central.
