I'm logging with log4j2
log4j2.xml :
<Configuration>
<Appenders>
<JDBC name="MySQLDatabase2" tableName="log4j2">
<ConnectionFactory class="my.ConnectionFactory"
method="getConnection" />
...
<AsyncRoot level="trace">
<AppenderRef ref="MySQLDatabase2" />
ConnectionFactory class :
public static Connection getConnection() throws SQLException {
dataSource = new org.apache.commons.dbcp2.BasicDataSource();
dataSource.setUp ( url, user, pass, driver )
dataSource.setDefaultAutoCommit(false);
dataSource.setAutoCommitOnReturn(false);
dataSource.setRollbackOnReturn(false);
dataSource.setValidationQuery("SELECT 1");
// Connection connection = dataSource.getConnection();
// connection.setAutoCommit(true); // no change, first is SET
autocommit=(0|1) and log4j2 next is SET autocommit=0
// return connection;
return dataSource.getConnection();
In code call :
org.apache.logging.log4j.Logger.trace("hello")
Finally calling logger,
use JDBC Appender
and get a connection from the BasicDataSource pool.
And continu outside my code with the unwanted transactional statement.
For writing log in my database.

Something is not clear to me: are you in control of calling JDBC or are you
using Log4j's JDBC Appender or something else? You description is not
detailed enough for me to understand who does what.
