tiny helper to enable hibernate sql trace logging and resotring previous log level

SqlLog.java

import org.slf4j.LoggerFactory;

import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.Logger;

public class SqlLog {

	private static final Logger LOG =
	        (Logger) LoggerFactory.getLogger(SqlLog.class);

	private static final Logger sql =
	        (Logger) LoggerFactory.getLogger("org.hibernate.SQL");
	private static final Logger binder = (Logger) LoggerFactory
	    .getLogger("org.hibernate.type.descriptor.sql.BasicBinder");

	private static final Level sqlLevel = sql.getLevel();
	private static final Level binderLevel = binder.getLevel();

	public static void trace() {
		sql.setLevel(Level.DEBUG);
		binder.setLevel(Level.TRACE);
		LOG.debug("SQL Trace enabled");
	}

	public static void restore() {
		sql.setLevel(sqlLevel);
		binder.setLevel(binderLevel);
		LOG.debug("SQL Trace disabled");
	}
}
