Enabling MySQL general query log with JDBC

Question

Is there a way to enable MySQL general query logging through JDBC? The closest thing I have found through my search is the ability to log slow queries through JDBC (http://d

Answer 1

You can enable logging in the JDBC URL like this:

jdbc:mysql://host/db?logger=com.mysql.jdbc.log.Log4JLogger&profileSQL=true

Other logging backends are available (CommonsLogger, Slf4jLogger, JDK14Logger). I believe direct Log4J logging was dropped at some point due to licencing issues so it might not work with your version of the JDBC driver.

Naturally, you'll need the relevant logging library's JAR in your classpath, and a configuration file (log4j.properties). I would set the root level to TRACE first to see what's happening and tighten it up by log level and category once you see what's being logged.
