jdbcdslog provides 3 loggers(in terms of log4j and jakarta commons) to maintain logging level:

• org.jdbcdslog.ConnectionLogger - trace connection details. It produces following log entries:

56 [main] INFO org.jdbcdslog.ConnectionLogger - connect to URL jdbc:hsqldb:. with properties: {user=sa}

• org.jdbcdslog.StatementLogger - trace statements sent to DB. It produces following log entries:

62627 [http-8080-1] INFO org.jdbcdslog.StatementLogger - java.sql.PreparedStatement.executeQuery select id, email from user where username = ? parameters: {'admin'} 12ms.

• org.jdbcdslog.SlowQueryLogger - trace slow statements sent to DB. If query takes more time then specified by jdbcdslog.slowQueryThreshold, it will be logged.

• org.jdbcdslog.ResultSetLogger - trace query results. It produces following log entries:

62118 [http-8080-2] INFO org.jdbcdslog.ResultSetLogger - java.sql.ResultSet.next {1234, 'root@a.com'}

All SQL trace entries are available on INFO and ERROR levels.

DEBUG level for other jdbcdslog classes will produce tons of debug log entries. Usually you don't want to turn it on.
